We can define aliases like this: SELECT age ALIAS myage FROM employee;

This query is correct: SELECT * FROM employee WHERE EITHER age = 25 OR age = 30;

MySQL uses standard SQL.

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

This query copies data from table2 to table1: INSERT INTO table2 SELECT * FROM table1;
