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

The HAVING statement must be used along with the GROUP BY statement.

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

Querying directly from a table takes more time than querying from a view.

This query is correct: SELECT * FROM employee WHERE age IN (20,21,22);
