Bonnie that is a great point. I just wish I could simply use Like '2004-05-04%' :(

You rock as usuall,

>>While searching for all records on a particular day a where clause is used like "where logdate = @logdate", when they are passing @logdate as '01/01/2004'. '01/01/2004' really means '01/01/2004 00:00:00.000' and will not return data for the complete day.

>>The problem can be solved by using the between clause. The where clause for such a query should be "where logdate between @logdate and @logdate2", where @logdate2 is @logdate + 1. The between clause can make use of an index if it exists, where using a convert function like "where convert(varchar,logdate,101) = @logdate" would not and it would slow down the query.

Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen."
