Oracle Solution for Error ora-06571

ORA-06571: Function string does not guarantee not to update database

What triggered the Error:

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.

What should we do to fix it:

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.
