ORA-06571: Function [string] does not guarantee not to update database
Cause: There are two possible causes for this message:* A SQL statement references a packaged, PL/SQL function that does not contain a pragma that prevents the database from being updated.* A SQL statement references a stand-alone, PL/SQL function that contains an instruction to update the database.
Action: If the referenced function is a packaged, PL/SQL function: Recreate the PL/SQL function with the required pragma; be certain to include the ''Write No Database State'' (WNDS) argument in the argument list of the pragma. If the referenced function is a stand-alone, PL/SQL function: Do not use the function.
Error Type: ORA
