The IN Operator

The IN Operator :

The IN operator allows you to specify multiple values in a WHERE clause.

SQL IN Syntax :

SELECT column_name(s)
FROM table_name
WHERE column_name IN (value1,value2,...)
-----------------------------------------
IN Operator Example
The "Persons" table:

P_Id LastName FirstName Address City
------------------------------------
1 Hansen Ola Timoteivn 10 Sandnes
2 Svendson Tove Borgvn 23 Sandnes
3 Pettersen Kari Storgt 20 Stavanger

Now we want to select the persons with a last name equal to "Hansen" or "Pettersen" from the table above.

We use the following SELECT statement:

SELECT * FROM Persons
WHERE LastName IN ('Hansen','Pettersen')

The result-set will look like this:

P_Id LastName FirstName Address City
------------------------------------
1 Hansen Ola Timoteivn 10 Sandnes
3 Pettersen Kari Storgt 20 Stavanger
