Slow SP with date parameters solved.

By Virgilio Licovali Bustos Ramirez,

When i use datetime fields in the where clause like timestampfield > {ts '2010-01-01 00:00;00'} and timestampfield < {ts '2010-01-31 23:59:59.998'} or timestampfield between {ts '2010-01-01 00:00:00'} and {ts '2010-01-31 23:59:59'} the query runs fine, but if i need to use it on stored procedeures like parameters like this:

CREATE PROCEDURE withDates

@d1 as datetime,

@d2 as datetime

AS

BEGIN

select * from tablewithdates where datetimefield between @d1 and @d2

END

 

The Procedure becomes slow, if try the same query with the direct values the query runs very fast. I don't know if there is an answer to this or if it is a bug, but, in many forums the people has the same problem: very slow stored procedures that uses date parameters.

If you use the code that i propose. The SP becomes fast as if you put the direct values. Enjoy.
