Alter row_format to dynamic in MySQL?

MySQLMySQLi Database

To alter row_format to dynamic in MySQL, following is the syntax:

ALTER TABLE yourTableName ROW_FORMAT=DYNAMIC;

Let us first create a table:

mysql> create table DemoTable
(
   CustomerId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   CustomerName varchar(200),
   CustomerAge int,
   CustomerAddress varchar(200)
);
Query OK, 0 rows affected (0.73 sec)

Let us check the description of table using DESC command:

mysql> desc DemoTable;

This will produce the following output:

+-----------------+--------------+------+-----+---------+----------------+
| Field           | Type         | Null | Key | Default | Extra          |
+-----------------+--------------+------+-----+---------+----------------+
| CustomerId      | int(11)      | NO   | PRI | NULL    | auto_increment |
| CustomerName    | varchar(200) | YES  |     | NULL    |                |
| CustomerAge     | int(11)      | YES  |     | NULL    |                |
| CustomerAddress | varchar(200) | YES  |     | NULL    |                |
+-----------------+--------------+------+-----+---------+----------------+
4 rows in set (0.00 sec)

Following is the query to alter row_format to dynamic:

mysql> alter table DemoTable ROW_FORMAT=DYNAMIC;
Query OK, 0 rows affected (1.05 sec)
