MySQL 1054: Unknown column.

  1. Verify the column name in the query against the actual columns in the table. Use the command:


DESCRIBE yourtablename;
Replace `yourtablename` with the name of the table you are querying.

  1. Check for typos in the column name in your SQL query.



  1. If you are using table aliases, ensure that the column name is correctly prefixed with the correct table alias.



  1. If the query involves multiple tables, ensure that the column exists in the correct table. Use the `DESCRIBE` command for each table involved.



  1. Check if the database schema was recently changed and the application code was not updated accordingly. Confirm the current schema and adjust your query.



6. Ensure that your query's syntax is correct for specifying column names, especially if you're using functions or expressions.
