"Function %s 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.
