Question

I have a query that takes 2 datetimes as parameters and I need to write a where clause to get the records that are in between. These are not just dates but dates with times (ie. 1/28/2012 9:45)

So far, I this:

where d.RecordDateTime > StartDate && d.RecordDateTime < EndDate

Should I be rewritting these as:

where d.RecordDateTime > StartDate.Date && d.RecordDateTime < EndDate.Date

or is it fine as is.

Thanks.

Your current query definitley works… depending whether you want the result to include StartDate and/or EndDate it should be changed a little bit:

where d.RecordDateTime >= StartDate && d.RecordDateTime <= EndDate

IF you change the query as you proposed in your question then you would make it include all in the result independent of time – although it would miss rows with a time like 00:00:00 or even miss a whole day (the EndDate).
