mysql> USE test_db; Database changed mysql> CREATE TABLE tb_emp1 -> ( -> id INT(11), -> name VARCHAR(25), -> deptId INT(11), -> salary FLOAT -> ); Query OK, 0 rows affected (0.37 sec)Copy after loginCheck whether the data table is created successfully:
mysql> SHOW TABLES; +--------------------+ | Tables_in_test_db | +--------------------+ | tb_emp1 | +--------------------+ 1 rows in set (0.00 sec)
