Structured Query Language tutorial ( in operator )

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
