Thanks all for the suggestions. I've learned how to do a pass-thru query then hit the next stumbling block : how to use information from Access within the pass-thru query. When I tried a where clause with a '= Forms!frmWaterQuality!StartTime', it didn't like it at all. The same is true for executing a stored procedure using fields from an Access form as parameters.

Is there a way to do this? The referencing notation of Access doesn't come close to what SQL will accept. I don't know how or if it is even possible to define a variable in Access that I can use in a SQL pass-thru query.
