I have a stored procedure where the performance is bad. The Execution plan shows 5 table scans each of cost 12%. The data is being pulled from the table using the following where clause.
where (datestamp>getdate() - 'sep28 1902 12:00 AM')
I already have an index on Datestamp column but still Table scan is happening. There is no restriction on avoiding index is specified in the query.
If the index is place inappropriately there would be index scan but here I have table scan.
Could anyone help me in finding out why this is happening.
