The Advanced JDBC Column Handler processes data retrieved by the JDBC database driver. If you encounter any problems, the first step is to ensure that the database driver is performing correctly. Testing the database driver outside of forge will verify this; a good first step is to test the driver using a standalone Java program.
If you experience errors using the column handler with Oracle's JDBC drivers, you should check the following guidelines:
If you are using Oracle 9i or later, make sure that you are using the JDBC driver implementation that came with your Oracle server installation. If you have a patched revision of the Oracle server (for example. 9.2.0.6), it is likely that the patch contains an updated JDBC driver. Check to make sure that you are using the patched JDBC driver.
If you are using earlier versions of Oracle 9i, try using the OCI driver instead of the thin driver. Later versions of the Oracle 9i thin driver have full support for CLOBs and BLOBs, but earlier Oracle 9i drivers do not.
If you are using Oracle 8i or earlier, contact Oracle Customer Support.
