Thanks for responding. Sorry for delayed acknowledgement.
It's possibly an instance of NIH syndrome ......... but I prefer my kludge (convert to a character representation of a date) to yours. I think it shows the desired result more clearly. I also discovered that
ldDate = DATE()
SQLEXEC(lnHandle,"SELECT * FROM myTable WHERE DATE(dtField) = CAST(?ldDate as date)")
also works. I don't know which is the fastest expression (and don't think the difference would be at all significant) but I think this is the most clear, but that's a subjective opinion.
