This query retrieves the first 3 rows: SELECT * FROM employee LIMIT 3;

This statement adds a column: ALTER TABLE employee DROP COLUMN age.

This query retrieves the employees whose names end with h: SELECT * FROM employees WHERE name LIKE 'h%';

This query is correct: UPDATE table_name SET column1=value1;
