SQLState 23000 what is causing this?

I am getting this error: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (..MY DB USER...users, CONSTRAINT users_ibfk_1 FOREIGN KEY (security_level) REFERENCES security (security_id) ON DELETE CASCADE)
how do I fix this?

Response from A.I:

The error message indicates a foreign key constraint violation when trying to add or update a row in the users table. Specifically, the security_level column in the users table is referencing a security_id in the security table, but the referenced security_id does not exist.

To fix this issue, I need to:

  1. Verify the existing security_id values in the security table.
  2. Ensure that the security_level values in the users table match one of the security_id values in the security table.
  3. If there are mismatched values, either update the security_level values in the users table to match existing security_id values or add the missing security_id values to the security table.
