Thanks for reporting this. I too am having problems reproducing this.
When you talk of SQL with parameter lists, do you mean
PreparedStatements? I tried them out as well. You can script these also
p UPDATE Parent SET NAME = ?, STUFF = ? WHERE NAME = ?;
Is there any more info you can give on this problem?
You also sent an earlier email suggesting that sensible default formats
be adopted for TIMESTAMP and equivalent types. I think that's a good
idea and I'll put it in a future release.
