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

In this article Aaron Bertrand is writing about your problem. It's really long and very detailed.

One Way would be this:

CREATE FUNCTION dbo.SplitStrings_XML
(
   @List       NVARCHAR(MAX),
   @Delimiter  NVARCHAR(255)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
   RETURN 
   (  
      SELECT Item = y.i.value('(./text())[1]', 'nvarchar(4000)')
      FROM 
      ( 
        SELECT x = CONVERT(XML, '' 
          + REPLACE(@List, @Delimiter, '') 
          + '').query('.')
      ) AS a CROSS APPLY x.nodes('i') AS y(i)
   );
GO

With this function you only call:

WHERE AREA IN (SELECT Item FROM dbo.SplitStrings_XML(@communityDesc, N','))

Hope this could help you.
