There are different versions of the ODBC standard (v2, v2.5, v3 ...) - IIRC there are details somewhere on Microsoft's sites (it's their standard). If in doubt, use the middle-one. I believe the psqlodbc30w.dll also supports multi-byte character sets, but don't quote me on that. -- Richard Huxton Archonet Ltd
Thanks for your prompt reply . I use psqlodbc30w.dll one week ago .But I found it caused my Delphi client program to fail in the running progress frequently. I replaced it with the middle one ,there was no any problem . My database was postgres7.3.4 on redhat linux 9 . My client program was compiled with Delphi 6(SP2) using ADO-ODBC connection . ======================================= >On Thursday 15 January 2004 06:19, LitelWang wrote: >> Can you give the details ? > >There are different versions of the ODBC standard (v2, v2.5, v3 ...) - IIRC >there are details somewhere on Microsoft's sites (it's their standard).
