Re: FreeTDS 0.82 returning ODBC v2 values instead of ODBCv3 values

The Heterogeneous Services (ODBC connector) in Oracle got re-written in
version 11 can only do ODBC v3 and assumes that the ODBC driver is v3.
The previous version would figure out if the driver was v2 or v3 and
could do both.

ODBCv3 values

hi,

when i am connecting to odbc from qt in linux i had to add connection
parameter
SQL_ATTR_ODBC_VERSION=SQL_OV_ODBC3, otherwise it also didn't worked
properly

i don't know oracle, but try to find if you can set connection
parameters
somewhere, it might help in your case too

columns being ignored.  The datatype code listed for the columns being
ignored is 11 (ODBC v2) instead of 93 which is the ODBC v3 code for
datetime or timestamp.  I need FreeTDS to always use the ODBC v3 values.
Is there any way to force it to default to ODBC v3?  Or is there
something in unixODBC that can be set to force ODBC v3?  Anybody who
upgrades to Oracle 11 will lose the ability to use FreeTDS if it can't
do ODBC v3 by default.

being ignored due to being datatype 11.
