SQL “if exists…” dynamic query

Question

Suppose I have a query stored in a variable like this (it\'s actually dynamically populated and more complex, but this is for demonstration purposes):

DECLAR         


        

Answer 1

I know this answer is too late. but, I'm leaving this here to help someone else to use IF EXISTS with a dynamic query.

This is how you should do it with dynamic queries.

DECLARE @Query VARCHAR(MAX)

SET @Query = 'SELECT * FROM [dbo].[MyTable]'

SET @Query = 'IF EXISTS (' + @Query + ')
                BEGIN
                    -- do something
                    print ''1''
                END
            ELSE
                BEGIN
                   -- do something else
                   print ''0''
                END
            '

exec (@Query)

Hope this helped someone. Vote if it did :)
