Create a temporary table similar to a regular table with MySQL LIKE
Let us first create a table −
mysql> create table DemoTable1 ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, Name varchar(100) ); Query OK, 0 rows affected (0.59 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1(Name) values('Chris');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable1(Name) values('Robert');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable1(Name) values('Mike');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable1(Name) values('Sam');
Query OK, 1 row affected (0.07 sec)Display all records from the table using select statement −
mysql> select *from DemoTable1;
This will produce the following output −
+----+--------+ | Id | Name | +----+--------+ | 1 | Chris | | 2 | Robert | | 3 | Mike | | 4 | Sam | +----+--------+ 4 rows in set (0.00 sec)
Following is the query to create a temporary table LIKE a regular table −
mysql> create temporary table DemoTable2 like DemoTable1; Query OK, 0 rows affected (0.04 sec)
Let us check the description of the table −
mysql> desc DemoTable2;
This will produce the following output −
+-------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------+--------------+------+-----+---------+----------------+ | Id | int(11) | NO | PRI | NULL | auto_increment | | Name | varchar(100) | YES | | NULL | NULL | +-------+--------------+------+-----+---------+----------------+ 2 rows in set (0.04 sec)
