Vantage does not support returning inline LOBs in an external procedure. If you need an external procedure to process inline LOBs, then place an SQL procedure wrapper around the external procedure.

To do this, use the following general procedure.

  1. Create an SQL procedure that calls the external procedure and also returns an inline LOB.
  2. Create an external procedure that returns the LOB AS LOCATOR to the SQL procedure created in the first step.

The SQL procedure then returns the inline LOB to the requestor.
