Jin-Chong,
Thanks for the suggestion. I tried a couple of variants of this in the odbc.sbo file, but without any luck so far. I'll try a few more and let you know the results.
Though this raises a slightly different question. Do you know why there is no postgresql.sbo file? I would have thought that this is where I should have made such a change, but there is no such file as there is with other DB types.
Thanks,
Josh
