Hi Homer, nice to hear from you again, I have not try it now but I'm pretty sure I have done this in the pass. It depends on the way IBDac deals with variants and timestamp because you are using an implicit casting. In that case you should use encodedatetime or encodetime, you can find it in the help.



Regards,


Al

Wow. Thanks for the quick response. I tried the "QuotedStr" solution but got yet another error: 'Could not convert variant of type (String) into type (Date).'

I try to stay as far away from BDE as possible. I'm using IBDac components (the latest Devart stuff).

I haven't tried to create an "INSERT INTO" query, but that's next. Perhaps DSQL will handle the time field properly.
