sql server 2005 express  

I have a stored procedure that I would like to speed up in someway.

I'm using the "like"  operator...


Is there another way the same results but faster... ?


Thanks

I'd put (nolock) after each table name

FROM dbo.SapData (nolock) INNER JOIN
WwgExtra.dbo.WwgExtra (nolock)

Also make sure that you have indexes on the fields that you are joining the tables on (SapData.ITEM and SalAltData.ITEM).  Also put an index on SapData.MFRNUM.

the problem here is the like operator,the only way to improve the like operation here is to have full text indexing on that column, and modify your query accordingly. but it can add some overhead to the system
