We are having a similar issue. Did you ever find a resolution?
Are you trying to access date in FileMaker from SQL Server or are you trying to access data in SQL Server from FileMaker?
The original post seems to combine steps for both so which they wanted is not clear. (And I haven't done much with ODBC in FileMaker, so I may not be able to help you do much more than clarify this question.)
I am trying to access an Oracle database (11G) via ODBC. It works great when I'm using it from FM Pro but when I attempt to access from FM Go with an iPad, I get an ODBC mismatch error even though it is the exact version on both machines???
You may want to ask that question in the FM GO forum (see tabs at top of this screen) if you have not already done so.
:-) I have ... thanks Phil!
