How to create a new table from the first table using MySQL LIKE?
Let us first create a table −
mysql> create table DemoTable1 ( EmployeeId int NOT NULL AUTO_INCREMENT PRIMARY KEY, EmployeeName varchar(50) ); Query OK, 0 rows affected (0.48 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1(EmployeeName) values('Tom'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable1(EmployeeName) values('Mike'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1(EmployeeName) values('Emma'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable1(EmployeeName) values('Sam'); Query OK, 1 row affected (0.10 sec)
Display all records from the table using select statement::
mysql> select *from DemoTable1;
This will produce the following output −
+------------+--------------+ | EmployeeId | EmployeeName | +------------+--------------+ | 1 | Tom | | 2 | Mike | | 3 | Emma | | 4 | Sam | +------------+--------------+ 4 rows in set (0.00 sec)
Following is the query to create a new table from another table using LIKE in MySQL −
mysql> create table DemoTable2 LIKE DemoTable1; Query OK, 0 rows affected (0.55 sec)
Let us check the description of the table −
mysql> desc DemoTable2;
This will produce the following output −
+--------------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------+-------------+------+-----+---------+----------------+ | EmployeeId | int(11) | NO | PRI | NULL | auto_increment | | EmployeeName | varchar(50) | YES | | NULL | | +--------------+-------------+------+-----+---------+----------------+ 2 rows in set (0.00 sec)
