Dear James K. Lowden,
I have reworked a little bit my patch and have implemented unit tests.
Actually, in the old patch I have missed the comparison checking if
there is still data available. This comparison was again checking
processed number of bytes in output buffer against size of source. And
BINARY to CHAR conversion (which I said I haven't checked) was actually
wrong and even not needed.
Additionally, I have implemented the CHAR to BINARY conversion for
SQLPutData. The unit test is checking both SQLGetData and SQLPutData
The patch against current CVS head is available:
and patch against FreeTDS-0.82 is here:
