Identifies the UDF, UDM, or stored procedure to be run in debug mode the next time the function, method, or stored procedure is invoked.
For more information, see CREATE PROCEDURE and REPLACE PROCEDURE (External Form), CREATE FUNCTION and REPLACE FUNCTION (External Form), CREATE METHOD, and “C/C++ Command-line Debugging for UDFs” in Teradata Vantage™ - SQL External Routine Programming , B035-1147 .
Required Privileges
You must have the EXECUTE FUNCTION and the DROP FUNCTION privilege on the function or stored procedure you want to debug.
You must have the UDTMETHOD and the UDTUSAGE privileges for the method you want to debug.
ANSI Compliance
SET SESSION DEBUG FUNCTION is a Teradata extension to the ANSI SQL:2011 standard.
Usage Notes
- Debugging is turned off for the function.
- Debugging is turned on for another function with a subsequent SET SESSION DEBUG FUNCTION statement.
- The session terminates.
After you set debugging on for a function and a query invokes the function, the function is passed to the debugger. If a debugger is not active, the query cannot complete until the debugger is started, attaches to session running the query, and allows all instances of the function being debugged to complete.
