I have a weird problem ? When preparing sql statements with ? placeholders, hdbc-odbc adds a space to a string value at the end.

I've run into that bug too. I'm pretty sure its an issue with hdbc-odbc, but haven't wanted to patch it without testing it across a few other configurations., which I haven't had time/found straightforward to do. John Goerzen sent a message recently explaining that HDBC needs some more eyes/contributors on it, and particularly the ODBC backend [1]. In any case, for the moment, you can always avoid bound parameters with hdbc-odbc. I've found support for them to be partial at best anyway.
