What is IN Logical Operator :
IN logical operator is used when we want to return the row if specified value matches with any value in the sub-query or a list.The IN Logical operator is going to be true if the operand is equal to one of the list of expressions.
Let's say that we have dbo.Customer table with below rows. We want to return the rows where CountryShortName is equal to 'PK' OR 'US'.
Createtable dbo.Customer
(Id int,
FName VARCHAR(50),
LName VARCHAR(50),
CountryShortName CHAR(2))
GO
insertinto dbo.Customer
Values (
1,'Raza','M','PK'),
(2,'Rita','John','US'),
(3,'Sukhi','Singh',Null),
(4,'James','Smith','CA'),
(5,'Robert','Ladson','US'),
(6,'Alice','John','US')
Let's write our query by using IN logical operator.
Select * From dbo.Customer
where CountryShortNameIN ('US','PK')
