Index is not faster any more

After I have modified couple columns my database access is very slow in that table. (Update Statistics Rx_Control is in Progress). It happened before I got back to same status by restoring the data. I really don't want to restore this time. Please some one post a sloution.

Thank you

Are these updates on any index columns. Try rebuilding the index using
DBCC dbreindex

The index is ok, Some how execution plan changed. Now every this ok after uodating the statistics. how ever the foloowing problem remains.

from query analyser.
select * from table_name where store = '3' --is faster and using index scan.

Declare @.store as int
set @.store = '3'
select * from table_name where store = @.store --is very slow and using table scan.

I don't how to fix this, it was ok before.
