To achieve this with LIKE operator, the following is the syntax −
CREATE TABLE yourTableName2 LIKE yourTableName1;
To understand the syntax, let us create a table and insert some records into it. The following is the query to create a table −
mysql> create table Employee −> ( −> EmployeeId int −> , −> EmployeeName varchar(100) −> ); Query OK, 0 rows affected (0.54 sec)
Inserting records into the table with the help of insert command. The query is as follows −
mysql> insert into Employee values(1,'Carol'); Query OK, 1 row affected (0.18 sec) mysql> insert into Employee values(2,'John'); Query OK, 1 row affected (0.16 sec) mysql> insert into Employee values(3,'Johnson'); Query OK, 1 row affected (0.11 sec)
Displaying all records with the help of select statement. The query to display all records are as follows −
mysql> select *from StudentTable;
The following is the output −
+------+---------+ | Id | Name | +------+---------+ | 3 | Johnson | +------+---------+ 1 row in set (0.00 sec)
Now you can implement the above syntax which I discussed in the beginning. The query is as follows to create a table with the help of LIKE operator.
mysql> create table StudentModifyTableDemo Like Employee; Query OK, 0 rows affected (0.50 sec)
You can check the definition of the new table with the help of desc command. The query is as follows −
mysql> desc StudentModifyTableDemo;
The following is the output −
+--------------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +--------------+--------------+------+-----+---------+-------+ | EmployeeId | int(11) | YES | | NULL | | | EmployeeName | varchar(100) | YES | | NULL | | +--------------+--------------+------+-----+---------+-------+ 2 rows in set (0.12 sec)
Now you can insert all records of Employee table to StudentModifyTableDemo table.
The query is as follows −
mysql> insert into StudentModifyTableDemo select *from Employee; Query OK, 3 rows affected (0.16 sec) Records: 3 Duplicates: 0 Warnings: 0
Now you can check all records are present in the second table or not. The query is as follows −
mysql> select *from StudentModifyTableDemo;
The following is the output −
+------------+--------------+ | EmployeeId | EmployeeName | +------------+--------------+ | 1 | Carol | | 2 | John | | 3 | Johnson | +------------+--------------+ 3 rows in set (0.00 sec)
