How to easily 'create table from view' syntax in MySQL?

MySQLMySQLi Database

You can create a table from view using create table select syntax. The syntax is as follows −

CREATE TABLE yourTableName AS SELECT
yourColumnName1,yourColumnName2,yourColumnName3,........N from yourViewName;

To run the above query, first you need to create a table and after that you need to create a view on that table. After that run the query.

First, you need to create a table. The query to create a table is as follow −

mysql> create table StuedntInformation
   -> (
   -> Id int,
   -> Name varchar(100)
   -> );
Query OK, 0 rows affected (0.54 sec)

Above, we have created a table. After that you need to create a view. The query to create a view is as follows −

mysql> CREATE VIEW view_Student AS SELECT Id,Name from StuedntInformation;
Query OK, 0 rows affected (0.11 sec)

Now I have created a view with the name ‘view_Student’. Check the view using show command.

The query is as follows −

mysql> SHOW CREATE VIEW view_Student;

Output

+--------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+
1 row in set (0.00 sec)

We will use the above view name ‘view_Student’ to create a table. The following is the query to create a table using view −

mysql> CREATE TABLE CreatingTableUsingViewStudent AS
   -> select Id,Name from view_Student;

Query OK, 0 rows affected (0.50 sec)
Records: 0 Duplicates: 0 Warnings: 0

Now you can check the DDL of a table using show command. The query is as follows −

mysql> show create table CreatingTableUsingViewStudent;

Output
