To make a column bigger in MySQL, you can alter the column using the ALTER TABLE command with CHANGE keyword. Here's an example: `ALTER TABLE your_table_name MODIFY column_name TYPE new_data_type NEW_COLUMN_NAME;` To delete unique values from a table, use the DELETE command with the DISTINCT keyword and WHERE clause. Here's an example: `DELETE FROM your_table_name WHERE column_name IN (SELECT DISTINCT column_name FROM your_table_name);`
