38002: modifying_sql_data_not_permitted

The modifying_sql_data_not_permitted error is an issue that crops up in PostgreSQL, a popular open source relational database system. It occurs when a user attempts to modify data that is not allowed or permitted by the database. The error message reads “modifying SQL data is not permitted.”

This error occurs when the user tries to modify data in the database without having the right privileges to do so. The user may be trying to modify data that is protected by the database, such as system tables or certain types of data. The error is also triggered when the user is not authenticated, or when they are using a user that has insufficient privileges to modify the data.

A common case of this error is when a user is attempting to modify data that has been created or modified by another user in the system. The user may be trying to update a record, delete a record, or insert a record without permission. The user may also be attempting to change user privileges or grant access to a database the user does not have the proper permissions for.

The best way to solve this issue is to ensure the user has the proper permissions to modify the data. This can be done by adding the user to the appropriate roles or groups in the PostgreSQL instance. Additionally, it is important to ensure that the user does not have access to any data that is not intended for them to modify.

Another option is to use PostgreSQL triggers to auditing or logging data manipulation together with check constraint or restrict delete and update functions. The triggers will also allow the data to be modified by the user in a safe and controlled manner according to their permissions.

Finally, it is also important to ensure that user authentication is enabled in the server. This will help to ensure that only authenticated users are able to access and modify the data in the system. This can be enabled in the PostgreSQL configuration file.

In conclusion, the error message “modifying SQL data is not permitted” occurs when a user attempts to modify data that they are not allowed or permitted to. The best way to fix this issue is to make sure the user has proper permissions and that they are authenticated on the server. Additionally, triggers, logging and check constraints can be used to ensure that a user is only able to modify data in a safe and controlled manner.
