How do I force a stored procedure to use an index?

How do I force a stored procedure to use an index?

I have an indexed table of 1,750,000 rows which gives excellent performance when doing a database query on a column which has a secondary non-unique index. When I try to perform a similar query in a stored procedure via a cursor however, it does a full table scan on every query. Is there a way that I can force it to use the index?  

RE: How do I force a stored procedure to use an index?


You can try and see if the UPDATE STATISTICS statement makes any improvement. Then the stored procedure know about the current amount of data, new indexes etc, and possible optimizations will be done.

Thanks Jarl. That did indeed help. It most definitely uses the index on simple conditionals in the stored procedure now. Now we just need to ensure that we don't write code that switches it off! smile



PS Is this the only MIMER forum on the web (it seems quiet) or are there others?
