Quick answer, you can't. You could instead use a table variable.

In addition to Eirikur's response when you declare variables with datatypes that have a size you should ALWAYS define the size. Defining varchar with no size will get the default size. Do you know what that is? Are you 100% certain it will not change in the next release of sql? Are you sure it hasn't changed in various version of sql over the years?

Hi Friends

This worked for me:

Declare @w_man as varchar(50)

set @w_man = 'julial,BEVERLEYB, Lucy'

That is NOT multiple values. It is a single string value that contains some characters and some commas. To deal with this you need to do one of two things. You will either need to use dynamic sql or split this into multiple values.

Depending on how you are trying to use the values the more appropriate variable may be a Table Variable and something like this.

DECLARE @w_man TABLE (

[Name] Varchar(50)

);

INSERT INTO @w_man ([Name])

SELECT 'Julial'

UNION

SELECT 'BEVERLYB'

UNION

SELECT 'Lucy'
