Unsupported Functionalities
The OSS ODBC/MX Client Driver does not support the following functionalities:
•
Windows-specific APIs that are used for driver installation and driver configuration.
•
Dynamic DLL loading while loading OSS ODBC/MX Client Driver, other ODBC
Drivers to external data sources (for example, Oracle or SQLServer).
•
Wide character support.
•
Windows-styled exception handling.
•
Asynchronous semantics. All calls are implemented synchronously. This implies
that SQLCancel can only be invoked on a statement handle after returning from the
last invocation on the handle, not when an operation is running. For example, a
runaway query cannot be stopped by the client application.
•
Cursor library.
•
Translate library.
•
Applications that use windows-specific function class or methods.
