Using variable in SQL LIKE statement

Question

I\'ve got a sproc (MSSQL 2k5) that will take a variable for a LIKE claus like so:

DECLARE @SearchLetter2 char(1)
SET @SearchLetter = \'t\'
SET @SearchLetter2         


        

Answer 1

This works for me on the Northwind sample DB, note that SearchLetter has 2 characters to it and SearchLetter also has to be declared for this to run:

declare @SearchLetter2 char(2)
declare @SearchLetter char(1)
Set @SearchLetter = 'A'
Set @SearchLetter2 = @SearchLetter+'%'
select * from Customers where ContactName like @SearchLetter2 and Region='WY'
