SQL_ACTIVE_STATEMENTS is deprecated/renamed in ODBC 3.x spec, and the new one is SQL_MAX_CONCURRENT_ACTIVITIES. You should try to use this with 3.x applications. SQL_MAX_CONCURRENT_ACTIVITIES returns SQLUINTEGER only, though it was a typo error as SQLUSMALLINT in ODBC spec. > > And this is my original problem - but here I can't find a reason: > If I try to call > > SQLColumnPrivileges (hstmt, NULL, 0, NULL, 0, > (SQLCHAR*)"patdat", SQL_NTS, NULL, 0) ? > > I get a error message "[Microsoft][ODBC Driver Manager] Driver > does not support this function" if I use myodbc V2.50.

We don't support yet.
