CREATE {TABLE | CLASS} <new_table_name> LIKE <old_table_name>

CREATE TABLE a_tbl(

id INT NOT NULL DEFAULT 0 PRIMARY KEY,

phone VARCHAR(10));

INSERT INTO a_tbl VALUES(1,'111-1111'), (2,'222-2222'), (3, '333-3333');

--creating an empty table with the same schema as a_tbl

CREATE TABLE new_tbl LIKE a_tbl;

SELECT * FROM new_tbl;
