What ODBC Conformance Level is supported by Oracle?

ODBC provides 4 conformance levels depending upon how much of the ODBC specification is implemented in the driver. The levels are:

• CORE API
• LEVEL 1
• LEVEL 2
• LEVEL 3 - latest spec.

The Oracle7 ODBC driver supports ODBC Version 2.5 and 3.0 Level 2 only.

Oracle does not support Level 3 ODBC, but Level 1 is all that is necessary to do standard operations. If you develop applications that will run on different databases, you might want to limit yourself to level 1 ODBC calls.
