Create new index to improve performance
Posted on 2008-10-23
I have a table with following structure:
ItemID BigInt Primary Key
In most queries, I am using ItemID for joins. But in some queries, need has arisen to fetch records on the basis of ItemName. I am noticing slight performance degradation as items list is growing.
I want to know that if I create an index on ItemName, will it improve the performance of the query? What else I can do to improve the performance of the query where I am fetching with ItemName and not ItemID?
