| Error | ORA-06573 |
Description | Function string modifies package state, cannot be used here | Cause | There are two possible causes for this message:
* A SQL statement references a packaged, PL/SQL function that does not contain a pragma containing the `Write no Package State` (WNPS).
* A SQL statement references a stand-alone, PL/SQL function that modifies a package state. A stand-alone, PL/SQL function referenced by a SQL statement cannot modify a package state.
| Action | If the function is a packaged, PL/SQL function: Recreate the function and include a pragma containing the `Write no Package State` (WNPS). If the function is a stand-alone, PL/SQL function: Delete the function from the SQL statement. |
