SQL Stored Procedure LIKE

Question

This is a simple question and I can\'t seem to think of a solution.

I have this defined in my stored procedure:

@communityDesc varchar(255) = NULL
         


        

Answer 1

A different approach is to use CHARINDEX(). However, using a function in a WHERE clause will slow down the performance.

WHERE CHARINDEX(','+area+',',','+@CommunityDec+',')> 0

If you area field is always 3 letters, you can simplify this.

WHERE CHARINDEX(area,@CommunityDec)> 0

This is a quick solution, but also a stop gap. A better solution is to change the string lookup approach to build a table with one row per search criteria and using a JOIN or sub query.
