Hello,
Can you share:
- The stored procedure DDL
- an export of your DataWindow
- the database connection settings used in your application
Can you enable the database tracing (e.g. SQLCA.DBMS = "trace ORA") and see what SQL update syntax the dbtrace.log file has generated (to redo it in a SQL*Plus session)?
Can you tell us if the last stored procedure parameter is an INPUT or not?
Jacob
