Introduction to PL/SQL nvl2In PL/SQL, nvl2() function is used to substitute the provided value or expression on the basis of null and not null value. It is basically an extension of the nvl() function of PL/SQL which takes 2 arguments. Function nvl2() takes 3 arguments, i.e. the original string or expression, other two being the substituted value based on the original string being null or not. Oracle provides the flexibility that the original string or expression can be of any data type and the substituted strings, i.e. other 2 arguments can also be of any data type except ‘LONG’. Oracle also performs specific actions if the 2 arguments except the original string are of different data type.

Syntax:
NVL2 (expr1, expr2, expr3)Where,
expr1: It is the string or the expression which is to be tested in the function nvl2.
expr2: It is the value which is to be returned as a result of the function if the expr1 is not null.
expr3: It is the value which is to be returned as a result of the function if the expr1 is null.
Return Type:
Function NVL2 returns the substituted value based on the string or expression provided.
How does nvl2 Work in PL/SQL?Important points related to the working of nvl2 function in PL/SQL are given below:
1. Function nvl2 in PL/SQL extends the functionality of nvl function provided by Oracle.
2. Function nvl2 basically decides the value to be returned from the query based on the null and not null value.
3. It takes 3 parameters, first being the original string or expression, second being the substituted string if the provided expression is not null and third being the substituted string if the expression is null.
4. Original string ‘expr1’ can be of any data type.
5. Parameters ‘expr2’ and ‘expr3’ also can be of any data type except long.
6. In case when the ‘expr2’ and ‘expr3’ are of different data types:
If ‘expr2’ is of numeric data type, Oracle implicitly checks which argument is of high precedence data type and then converts either expr2 or expr3 to high precedence data type and returns that data type.
If ‘expr2’ is a character data type, Oracle before comparing, converts the ‘expr3’ to a data type of ‘expr2’ and returns the VARCHAR2 in character set of ‘expr2’. Conversion of data type does not takes place if ‘expr3’ is a null constant.
Following versions of Oracle PL/SQL supports the nvl2() function:
Oracle 12c
Oracle 11g
Oracle 10a
Oracle 9i
Oracle 8i
Examples of PL/SQL nvl2Given below are the examples mentioned:
Example #1Code:
SELECT NVL2(NULL, 10, 98) as New_value FROM dual;Output:
Explanation:
In the above example, 3 arguments are provided in the nvl2() function. The first argument is ‘NULL’ which is a null value. So, according to the nvl2() function property, it will return expr3 if the provided expression is NULL.
So, in the above function ‘expr3’ is ‘98’. Hence ‘98’ is printed in the column ‘new_value’ on the console to the user.
Example #2Code:
SELECT NVL2('hello', 10, 98) as New_value FROM dual;Output:
Explanation:
In the above example, 3 arguments are provided in the nvl2() function. The first argument is ‘hello’ which is a character data type and is not null. So, according to the nvl2() function property, it will return expr2 provided in the function which is ‘10’ in the above example.
Hence ‘10’ is printed in the column ‘new_value’ on the console to the user.
Example #3Code:
SELECT NVL2(100, 'hello', 'hi') as string_value FROM dual;Output:
In the above example, 3 arguments are provided in the nvl2() function. The first argument is 100 which is a numeric data type and is not null. So, according to the nvl2() function property, it will return expr2 provided in the function which is ‘hello’ in the above example.
Hence ‘hello’ is printed in the column ‘string_value’ on the console to the user.
Example #4Code:
SELECT NVL2('', 'this is not null value', 'this is a null value') as string_value FROM dual;Output:
Explanation:
In the above example, 3 arguments are provided in the nvl2() function. The first argument is the null value which is represented as blank brackets ‘ ‘. So, according to the nvl2() function property, it will return expr3 provided in the function if the expression ot the original string is null. So expr3 is ‘this is a null value’ in the above example.
Hence ‘this is a null value’ is printed in the column ‘string_value’ on the console to the user.
Example#5Code:
SELECT NVL2('hello hello', 'this is for not null value', '34') as string_value FROM dual;Output:
Explanation:
In the above example, 3 arguments are provided in the nvl2() function. The first argument is the ‘hello hello’ which is not a null value. As we can see above, that both the expr2 and expr3 are of different data types, so the Oracle performs the implicit conversions and according to that appropriate action would be taken. So, according to the nvl2() function property, it will return expr2 provided in the function if the expression ot the original string is not null. So expr2 is ‘this is for not null value’ in the above example.
Hence ‘this is for not null value’ is printed in the column ‘string_value’ on the console to the user.
ConclusionAbove description clearly explains what the nvl2 function is and how it works in a PL/SQL block. For a programmer, working on real databases, it is important to understand the concept of null and not null values and how to deal with them according to the resulting data from the tables in various situations clearly. Data represented to the user is according to the requirements of the user and showing null values is not an appropriate choice in many cases. So this function helps to deal with such situations.

How Block Works In Pl/Sql?
Definition of PL/SQL Block
Basically, PL/SQL contains the different blocks to write a code, in another word we can say that the PL/SQL code we cannot execute in a single, so we need a group of code for a single element that we called the block. Normally the block contains the SQL instructions as well as PL/SQL statements. The PL/SQL block structure is predefined and in which we need to write the code in different blocks. The PL/SQL consists of three different types of blocks such as the Declaration section, Execution section, and Exception handling section. As per requirement, we can include the header section into a PL/SQL.

Web development, programming languages, Software testing & others
DECLARATION SECTION BEGIN EXCEPTION END;Explanation
In the above syntax, we use three different sections: the declaration section, execution section, and exception handling section. In the first section we can declare variables, in the second section that begins or we can say that execution section, here we write the executable statement as per requirement and the last section contains the exception handling statement and again it depends on the user requirement.
How block works in PL/SQL?Now let’s see how PL/SQL works as follows.
Basically, there are three different sections as follows.
1. Declaration sectionThis is the first section in the PL/SQL block and it is an optional part in PL/SQL block. In this section, we can declare the variables, exceptions, subprograms, cursor, collections, and different instructions as per the requirement. The declaration section has some important characteristics as follows.
This section is optional, and if no declarations are required, it can be omitted.
If a PL/SQL block is present, this should be the first part.
For triggers and anonymous blocks, this section begins with the term ‘DECLARE.’ This keyword will not be present in other subprograms. Instead, the declaration portion begins after the subprogram name definition.
The execution section should always come after this part.
2. Execution SectionThis is the second section of the PL/SQL block; the execution section always starts with the BEGIN keyword and ends with the END keyword. In this block, we just need to write at least one executable expression even if it is null, which means it is a mandatory section of the PL/SQL block. Some important characteristics of the execution section are as follows.
• The ‘END’ or the Exception-Handling section should come after this section (if present)
3. Exceptional handling sectionNow let’s see some important characteristics of the exception handling section as follows.
There is no reference name given for these blocks.
The term ‘DECLARE’ or ‘BEGIN’ is used to start these blocks.
These blocks can’t be saved for subsequent use since they don’t have a reference name. They must be designed and implemented in the same session.
It can include nested blocks that are either named or anonymous. It may be nested in any block as well.
These blocks can include all three components, with the execution portion being required and the other two sections being optional.
Basically, there are two types of Block in PL/SQL as follows.
1. Anonymous Block: in this block, there is no need to specify the name that means we need to create and use it in the same section as per requirement because an anonymous block is not stored on the server.
ExamplesNow let’s see the different examples of a block in PL/SQL for better understanding as follows.
Let’s see a very simple example of a block in PL/SQL as follows.
SET SERVEROUTPUT ON; BEGIN DBMS_OUTPUT.put_line('Welcome in first PLSQL Block'); END; /Explanation
In the above example, we start to write the block with the BEGIN keyword and end with the END keyword as shown in the above block. Inside the block, we write the statement that contains the execution section of the block. The DBMS_OUTPUT.put_line statement used as an output statement that means here we display the message by using this procedure and execution of block we use forward-slash (/) that instructs SQL * Plus to execute the block. The final output of the above block or procedure we illustrated by using the following screenshot as follows.
Let’s see another example as follows.
SET SERVEROUTPUT ON; DECLARE test VARCHAR2(200) := 'Welcome in PLSQL Block'; BEGIN DBMS_OUTPUT.put_line(test); END; /In this example we include the declaration section as shown, here we declare the test variable with varchar2 data type and it contains a string message as shown in the above procedure. The remaining code of this example is the same as the above example. The final output of the above block or procedure we illustrated by using the following screenshot as follows.
Now let’s see how we can include the exception section in the procedure as follows.
SET SERVEROUTPUT ON; DECLARE val_e number; BEGIN val_e := 10/0; EXCEPTION when zero_divide then dbms_output.put_line('Divide by zero error'); END; /Explanation
By using the above example we try to handle the exception in the block. In the execution section, we write the expression for the divide by zero exception with the EXCEPTION keyword as shown in the above example. After execution of this block, it shows a message like Divide by zero error. The final output of the above block or procedure we illustrated by using the following screenshot as follows.
ConclusionWe hope from this article you learn PL/SQL blocks. From the above article, we have learned the basic syntax of block and we also see different examples of the block. From this article, we learned how and when we use PL/SQL blocks.

How Does Commit Work In Oracle?
Introduction to Oracle COMMIT
The Oracle commit statement is used to end the current transaction and make it permanent whatever changes that were applied to a particular database during this current transaction (Transaction in Oracle database can be defined as a sequence of SQL statements that is treated by the database as a single unit) and also releasing the transaction locks and deleting all the checkpoints or savepoints created during the current transaction process and after the successful application of this COMMIT statement users are able to see the changes made in the database.[Text Wrapping Break]
Syntax:

Hadoop, Data Science, Statistics & others
We will look into the syntax of the COMMIT statement. The syntax is very simple for the COMMIT statement.
Let us now understand the various parameters used in the COMMIT clause.
Parameters of Oracle COMMITBelow are the Parameters of Oracle COMMIT:
1. WORK: It is optional. In simple terms, a COMMIT WORK or only COMMIT are equivalent and does not change the outcome.
3. WRITE Clause: This clause is also optional and this clause in itself has two parameters which are given below:
WAIT: It is the default setting. It means that the commit will return back to the client only after redo information is persistent in the redo log.
NO WAIT: This means that the commit will return back to the client irrespective of the status of the redo log.
4. FORCE Clause: Just like the above parameters even this one is also optional. This allows us to manually commit a corrupt transaction. The syntax for using FORCE clause is FORCE ‘string’, [integer]: To commit such in doubt or corrupt transactions we need to get the id of such transactions, In order to achieve that we need to query the DBA_2PC_PENDING. In case we want to commit a corrupt transaction by giving the transaction id in single quotes we can use FORCE CORRUPT ‘string’. If we want to commit all corrupted transaction we can use FORCE CORRUPT ALL.
How COMMIT Works in Oracle?Let us now understand how commit works in Oracle. A commit is used on a transaction to apply it into the database which means the database is altered. It can be used implicitly as well as explicitly. A transaction is an atomic unit which consists of one or more logical unit. So suppose transaction (consisting of SQL statements) increments the value in a savings account of a person stored in the oracle database. The changed data gets reflected after we commit the SQL statements. So, in this case, we are explicitly committing the statements but if we use any DDL statements like CREATE table then oracle implicitly commits the transaction. So in case of DML statements we have to commit explicitly. So, we can say that commit means user explicitly or oracle implicitly in case of DDL statements requests that the changes made by the transaction be made permanent in the database.
Examples to Implement COMMIT in OracleLet us now look at the below examples to understand better the COMMIT statement.
1. IMPLICIT COMMITIn this case, the database will implicitly commit in case of a DDL statement. In our case, we are going to create a new table named DEPARTMENT having three columnsdept_id,dept_name. Let us look at the query.
CREATE TABLE DEPARTMENT (dept_id VARCHAR2(25) PRIMARY KEY, dept_name varchar2(25) NOT NULL);
This query will be implicitly committed and we are not required to explicitly commit the transaction since it is defining a table structure in the database also known as DDL statement. Let us run the query in SQL developer and look at the result.
2. EXPLICIT COMMITIn the first example, we are going to use the simple commit statement to insert a row into the Customers table which consist of three columns. Let us look at the query for this.
Query:
COMMIT;
In the above statement, we are first using the DML statement and then explicitly using COMMIT to make the insert permanent.
Let us run the group of statements in SQL developer and look at the result.
If we see the above screenshot after the insert statement is executed the commit command is also executed.
3. COMMIT with COMMENT ClauseQuery:
Let us run the statements in SQL developer and look at the result.
As we can see in the above screenshot the statement has been successfully committed.
4. COMMIT Using FORCE ClauseLet us now apply the FORCE clause for doubt or corrupt transaction. To manually commit the corrupt transaction we will first query the table DBA_2PC_PENDING to find the transaction id of the corrupt transaction and then use the FORCE clause to commit it. Let us look at the query for the same.
COMMIT FORCE ‘12.10.12’
This, when executed, will force COMMIT of the corrupted transaction with id ‘12.10.12’.
ConclusionIn this article, we discussed the definition of the COMMIT statement and its syntax. We also discussed how the COMMIT works with various transactions. Later on, we discussed a few examples based on various cases to understand better.

How Does Typeof Work In Typescript?
Definition of TypeScript typeof
typeof in TypeScript has the same name as JavaScript but functions differently. typeof is used to differentiate between the different types in TypeScript. By the use of typeof we can differentiate between number, string, symbol, Boolean, etc. typeof can be used with any type in TypeScript; by the use of it, we can re-use the code by passing any parameter type. In the coming section, we will see more about the typeof in TypeScript to understand it better.
Start Your Free Software Development Course
Syntax:
As we know, typeof is a keyword that is used to deal with different types in TypeScript. Let’s see its syntax in detail for better understanding. See below;
typeof variable === "your_type"As you can see in the above line of syntax, we can directly use this typeof with the variable name which we want to calculate. After this, we can write our own logic as per the requirement. In the coming section of the article, we will discuss this usage in detail for better understanding.
How does typeof work in TypeScript?As we already know that typeof is used to deal with several types of typeof in TypeScript. This allows us to help us with the various type in TypeScript; we can reuse the same code for multiple types in TypeScript. In this section, we will see how to use this while programming in TypeScript. Let’s see its usage and understand it better for future use. See below;
Keyword usage:
typeof variable_nameIn the above lines of code, we are using typeof keyword with the variable. It will tell us the type of variable. After this, we can use this to perform any operation on it. Now see one sample example for typeof in TypeScript for beginners to understand its internal working. See below;
e.g. :
class Demo{ testFunction(val: any): any{ if(typeof val === "string"){ return val; } } } let demoobj = new Demo(); let result= demoobj.testFunction("i am string !!"); console.log(result);In the above example, we are creating one function which accepts any type of parameter. Inside the ‘Demo’ class, we have created one function named ‘testFunction’. Inside this function, we are using typeof keyword to compare the type of the variable being passed. typeof will return us the type of the parameter. This is similar to the instanceOf keyword already available. After the comparison, we can write our own logic as per the requirement. At the last to call the function in TypeScript we are creating an object of the class and calling the function. This function we have created takes one parameter; this parameter can be of any type because we have assigned the type as ‘any’ in the function declaration. This is how it works in TypeScript, like any other programming language. It has some benefits as well. Let’s discuss them each one by one;
1) By using typeof in TypeScript, we can easily make checks which can help us to get any exception further exceptions if we try to cast them incorrectly.
ExamplesIn this example, we are trying to use the typeof with numbers in Typescript; if the passes parameter matches with the string type, then it will return the value; otherwise, nothing will be printed.
Example #1Code:
class Demo{ testFunction(val: any): any{ if(typeof val === "string"){ return val; } } } console.log("Demo to show the usage of typeof in Typescript !!"); let demoobj = new Demo(); let result1 = demoobj.testFunction("i am string !!"); let result2 = demoobj.testFunction("i am string two !!"); let result3 = demoobj.testFunction("i am string three !!"); console.log("printing result of the function after typeof !!"); console.log("result one is::" +result1); console.log("result two is::" +result2); console.log("result three is::" +result3);Output:
Example #2In this example, we are trying to use the typeof with numbers in Typescript; if the passes parameter matches with the number type, then it will return the value; otherwise, nothing will be printed.
Code:
class Demo{ testFunction(val: any): any{ if(typeof val === "number"){ return val; } } } console.log("Demo to show the usage of typeof in Typescript !!"); let demoobj = new Demo(); let result1 = demoobj.testFunction(100); let result2 = demoobj.testFunction(400); let result3 = demoobj.testFunction(500); let result4 = demoobj.testFunction(500); let result5 = demoobj.testFunction(500); console.log("printing result of the function after typeof !!"); console.log("result one is::" +result1); console.log("result two is::" +result2); console.log("result three is::" +result3); console.log("result four is::" +result4); console.log("result five is::" +result5); Example #3In this example, we are trying to use the typeof with numbers in Typescript; if the passes parameter matches with the boolean type, then it will return the value; otherwise, nothing will be printed.
Code:
class Demo{ testFunction(val: any): any{ if(typeof val === "boolean"){ return val; } } } console.log("Demo to show the usage of typeof in Typescript !!"); let demoobj = new Demo(); let result1 = demoobj.testFunction(true); let result2 = demoobj.testFunction(false); let result3 = demoobj.testFunction(true); let result4 = demoobj.testFunction(false); let result5 = demoobj.testFunction(true); console.log("printing result of the function after typeof !!"); console.log("result one is::" +result1); console.log("result two is::" +result2); console.log("result three is::" +result3); console.log("result four is::" +result4); console.log("result five is::" +result5);Output:
ConclusionIn the typeof keyword easy to use and understand. We can easily check the type of the parameter by simply using the typeof keyword before the variable name. This is very handy to use with variables in TypeScript. We can compare integers, numbers, Boolean, symbols, undefined, strings, objects, etc., by using typeof in Typescript.

How Does Mysql Union Work
Introduction to MySQL Union
MySQL Union combines the output of two or more “SELECT” statements. The output of the “UNION” will be without duplicate rows. The number of fields in the table should be the same, and the data type of the columns should be the same. If you don’t want the duplicate rows to be ignored, we can do it with the “UNION ALL”. In the result set of the UNION table, the column name will be the same as the column name of the first select statement. In this session, let us learn more about the usage of the UNION and let see the examples of it: –

SyntaxNow let us see the syntax:
SELECT column_1, column_2,...column_n FROM First_tables [WHERE conditions] UNION [DISTINCT] SELECT column_1, column_2,...column_n FROM Second_tables [WHERE conditions]; How Does MySQL Union Work? Table1 create table uniona ( cola INT ); Table2 create table unionb ( colb INT );Insert data into the tables as below: – Below is for the “uniona” table.
insert into uniona values (99); insert into uniona values (95); insert into uniona values (94); insert into uniona values (93); insert into uniona values (92); insert into uniona values (91); insert into uniona values (99);Select the items for the table “uniona”: –
select * from uniona;Let us see the screenshot for the same: –
Insert data into the tables as below: – Below is for the “unionb” table.
insert into unionb values (99); insert into unionb values (34); insert into unionb values (35); insert into unionb values (33); insert into unionb values (32); insert into unionb values (31); insert into unionb values (30); insert into unionb values (29); insert into unionb values (28);Select the items for the table “unionb”: –
select * from unionb;Let us see the screenshot for the same: –
Now let us perform union operation on the above tables: –
select * from uniona union select * from unionb;Select the items for the table “uniona” and “unionb” and perform the union: –
Let us see the screenshot for the same: –
Example:
Now let us perform UNION on three tables as below: –
--Table1: - create table TEST_A ( cola INT ); --Table2: - create table TEST_B ( colb INT ); --Table3: - create table TEST_C ( colc INT ); insert into test_a values (1); insert into test_a values (2); insert into test_a values (3); insert into test_a values (4);Let us see the columns of the table: –
select * from test_a; insert into test_b values (1); insert into test_b values (5); insert into test_b values (6); insert into test_b values (7); insert into test_b values (8);Let us see the columns of the table: –
insert into test_c values (1); insert into test_c values (10); insert into test_c values (11); insert into test_c values (12); insert into test_c values (13);Let us see the columns of the table: –
Output:
Screenshot for the above: –
select * from test_a union select * from test_b union select * from test_cOutput:
Here in the above output, we need to check two things: –
The column name of the result set is the column name of the first “select” statement. Here it is “cola”.
The second thing is that we can see that there is a duplicate row in all the tables of value “1”. But in the result set, UNION ignores the duplicate because we have only one row of data, “1”.
Screenshot for the same: –
Example of MySQL UnionActual Table:-
create table St_marks ( subject_name varchar(20), marks int ); insert into st_marks values ('English', 98); insert into st_marks values ('Mathematics', 93); insert into st_marks values ('Physics', 78); insert into st_marks values ('Chemistry', 67); insert into st_marks values ('Art', 43); insert into st_marks values ('Music Class', 67); select * from st_marks;Backup table:-
create table St_marks_bkup ( subject_name varchar(20), marks int ); insert into st_marks_bkup values ('English', 98); insert into st_marks_bkup values ('Mathematics', 93); insert into st_marks_bkup values ('Physics', 78); insert into st_marks_bkup values ('Chemistry', 67); insert into st_marks_bkup values ('Art', 43); insert into st_marks_bkup values ('Music Class', 67); select * from st_marks_bkup;Output:
A screenshot for the above is given below: –
SELECT SUBJECT_NAME, MARKS FROM ST_MARKS UNION SELECT SUBJECT_NAME, MARKS FROM ST_MARKS_BKUP;Output:
The screenshot is for the same: –
ConclusionThings that need to remember are as below: –
MySQL Union combines the output of two or more “SELECT” statements. The output of the “UNION” will be without duplicate rows.
The number of fields in the table should be the same, and the data type of the columns should be the same. If you don’t want the duplicate rows to be ignored, we can do it with the “UNION ALL”.
In the result set of the UNION table, the column name will be the same as the column name of the first select statement.

How Does Clubhouse Waitlist Work?
The virtual world is abuzz with talk of Clubhouse – a new social networking app born in the unpropitious year of 2023. Its distinctive invite system and exclusivity, which could have restricted its growth, has actually made it all the more appealing, like most things in short supply.
On top of that, as it is an audio-only platform, going against the tide of social media apps drowning its users with visual streams, its idiosyncracies have somehow been well received. Also, since Clubhouse is only available on iOS devices (as of now), it is all the more restrictive as to who can join and who can’t.
Now that Clubhouse has gained enough traction to become the next best thing that most people are not a part of (FOMO is real), many are wondering how they can become a part of it. Sure, one can always get an invite from one’s friend(s) who’re already on Clubhouse. But what about the rest of us who’ve signed up and find ourselves way down the waitlist? And how long does one have to wait? Well, here’s all you need to know about it.
What is Clubhouse Waitlist?
There are a couple of ways one can get into Clubhouse – through an invite from someone who’s already got in, or by signing up for the waitlist. But since invites are in short supply, most people resort to the latter.
Basically, it works like this – you sign up for the waitlist and wait for someone to wave you in. It helps to have a friend already on Clubhouse who can do so and save you some time.
It doesn’t consume their invite so you don’t have to holler into the internet void, begging for someone to spend their invites on you.
How much time does Waitlist invite take?
There’s no clear range for how much time one has to wait on average before they’re waved in. Some lucky ones have had to wait no more than a few hours, while others had to wait months to get in. As things can be a little unpredictable and depend on whether any of your friends are existing Clubhouse members, we’d suggest you don’t hold your breath over it.
Do you surely get an invite via Waitlist?
Whether or not you can get into Clubhouse through the Waitlist (even after long periods of waiting) is not a matter only of time alone. One of your friends has to already be a part of Clubhouse for them to know that you’ve signed up for the waitlist. Once you’ve signed up on the waitlist, the Clubhouse algorithm will then identify your contacts that are already inside and send them a notification to waive you in. So, as the circle grows, there is a definite possibility that you will (eventually) become a part of Clubhouse.
Are there better ways to get an invite than Waitlist?
The most obvious way to get into Clubhouse, as we’ve mentioned before, is to get an actual invite from someone who’s already “in”. Most celebrities and famous influencers won’t have to go through much of a struggle to get an invite, but regular folk might have to wait until someone remembers to send them one. But there are a few other ways you can get an invite.
Via Forums
Clubhouse has “rooms” where people that share similar interests can come together and share their insights (or simply listen). This means that if you can connect with them, you might be able to get an invite to their Clubhouse chat rooms.
The best way to do so is to connect with Clubhouse users on other platforms and exchange contacts. If you can befriend enough existing Clubhouse users, you will have a higher chance of getting in when Clubhouse’s algorithm scans your contact list, find people that are already in, and send you an invitation.
There are multiple subreddits with Clubhouse users that may just be kind enough to get you in. Just drop a message in the community thread and say precisely why is it that you want. There are some who may share their invites for free, but a great majority of them will ‘sell’ them.
As there’s a real dearth of invites, a real Clubhouse invite-market has surfaced where people can spend a few bucks to become a part of Clubhouse. Similar listings are also seen on eBay, Craiglist, and buymeacoffee pages, but be wary as some of them are out there only to swindle you off of your money. Make sure you chat with the person who’s selling the invites and only pay if you think they’re authentic.
Many have also started a chain of free invites where one Clubhouse user sends an invite to someone who goes on to invite two more (as every Clubhouse user gets two invites in the beginning), and then two more, ad infinitum.
Via Social Media
Facebook and Instagram are one of the biggest social media platforms and it is very likely that you may come across people who are already on Clubhouse. Using hashtags such as #Clubhouseinvites or #Clubhouse and finding specific Clubhouse groups can speed up the process and get you in touch with Clubhouse users. All you have to do is to request them for an invite and, if they’re willing enough, they may share it with you.
Has anyone got an invite via Waitlist?
Yes, there are many who’ve got an invite via Waitlist. If that were not the case, Clubhouse wouldn’t have had the Waitlist method in place.
Just because it’s taking a long time to get in through the waitlist doesn’t mean that you won’t get in eventually. Make sure that you interact with people who’re already on Clubhouse and exchange contacts with them so that the algorithm can find you quickly.
Why I can’t join Waitlist?
If you’re not able to join the Waitlist, then it means that the waitlist is down for the moment.
You can check back in a couple of weeks and see if it’s up again. Until then, make sure that you get in touch with other Clubhouse members on forums or social media platforms to improve your chances of getting in once you do get to sign up for the waitlist.
Being an audio-only social media app, Clubhouse has seen a surprising jump in popularity with every other iOS user wanting to get in and be a part of the new fad. Just do what’s necessary, be patient, and you will get your invite soon enough.
