What is
PostgresDB 2F002: Modifying SQL Data Not Permitted
?
When encountering the error 2F002: Modifying SQL Data Not Permitted in Postgres, the user should immediately check the current transaction or session settings and the role permissions to ensure that the operation being attempted is allowed. Execute the following queries for immediate investigation:
- Check if the session is in read-only mode:
SHOW transaction_read_only;
If the result is on, modifications are not permitted. To change this for the current session (if permissions allow), run:
SET transaction_read_only = off;
- Verify the role's permissions:
SELECT rolname, rolinherit, rolcanlogin, rolreplication, rolbypassrls, rolconfig
FROM pg_roles
WHERE rolname = current_user;
This will show the current user's role and permissions, check if the role is allowed to make modifications.
- Check if the database is in read-only mode:
SELECT datname, datallowconn, datistemplate, datallowconn, datacl
FROM pg_database
WHERE datname = current_database();
This will help identify if the database itself restricts write operations.
- Examine any applicable row-level security policies that might be preventing the modification:
SELECT policyname, permissive, cmd, roles, qual, with_check
FROM pg_policies
WHERE schemaname = 'your_schema_name' AND tablename = 'your_table_name';
Replace your_schema_name and your_table_name with the actual schema and table names you are trying to modify.
If any of these checks indicate a restriction or misconfiguration preventing data modification, the user should adjust the settings accordingly, assuming they have the necessary permissions. If the issue persists despite these checks, further investigation into specific table-level permissions, database configuration, or system logs for more detailed error information might be necessary.
