I have a user who has Windows XP and uses MS Access to make an ODBC connection to a Sybase database. The ODBC driver is Sybase ASE 4.20.00.15.
When I try to set up a connection on his PC, I can see all the tables, but after pick one, I get "Reserved Error (-7748); there is no message for this error", and I get no data. If I try to make a connection using this driver on my PC, I get the same error. He is able to retrieve data through Excel using this driver.
Everyone else uses the Sybase System 11 ODBC driver, which works. It's my understanding that Sybase System 11 isn't compatible with Windows XP, though.
