Unknown column in field list

❌ Error​

Unknown column 'xyz' in 'field list'

📍 Context​

This error occurs when a query references a column that does not exist in the database table. It usually happens after schema changes or when a script expects a different SQL structure.

✅ Solution​

  • Check that the column exists in the target table.
  • Add the missing column:
    ALTER TABLE table_name ADD COLUMN xyz VARCHAR(255);
  • Update your script or SQL file to match the database schema.

ℹ️ Additional Information​

  • Always back up your database before altering tables.
  • Compare your current schema with the expected schema from the script’s SQL files.
  • For more details, refer to the MySQL documentation.
