Create a MySQL table from already created table selecting specific rows?
To create a table from an already created table, use CREATE TABLE AS SELECT statement. Let us first create a table −
mysql> create table DemoTable1318 -> ( -> Id int, -> FirstName varchar(10), -> LastName varchar(10), -> Age int -> ); Query OK, 0 rows affected (0.50 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1318 values(1,'Chris','Brown',21); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable1318 values(2,'David','Miller',24); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable1318 values(3,'Carol','Taylor',23); Query OK, 1 row affected (0.11 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1318;
Output
+------+-----------+----------+------+ | Id | FirstName | LastName | Age | +------+-----------+----------+------+ | 1 | Chris | Brown | 21 | | 2 | David | Miller | 24 | | 3 | Carol | Taylor | 23 | +------+-----------+----------+------+ 3 rows in set (0.00 sec)
Following is the query to create a table from an already created table selecting specific rows −
mysql> create table DemoTable1319 -> as select *from DemoTable1318 -> where Age IN(21,23); Query OK, 2 rows affected (0.81 sec) Records: 2 Duplicates: 0 Warnings: 0
Display all records from the table using select statement −
mysql> select * from DemoTable1319;
Output
+------+-----------+----------+------+ | Id | FirstName | LastName | Age | +------+-----------+----------+------+ | 1 | Chris | Brown | 21 | | 3 | Carol | Taylor | 23 | +------+-----------+----------+------+ 2 rows in set (0.00 sec)
