How can we have multiple virtuals GENERATED COLUMNS in MySQL table with CREATE TABLE statement?
It is quite possible to add multiple virtual generated columns in a MySQL table. It can be illustrated with the following example as follows −
Example
mysql> Create table profit(cost int, price int, profit int AS (price-cost), price_revised int AS (price-2)); Query OK, 0 rows affected (0.73 sec) mysql> Describe profit; +---------------+---------+------+-----+---------+-------------------+ | Field | Type | Null | Key | Default | Extra | +---------------+---------+------+-----+---------+-------------------+ | cost | int(11) | YES | | NULL | | | price | int(11) | YES | | NULL | | | profit | int(11) | YES | | NULL | VIRTUAL GENERATED | | price_revised | int(11) | YES | | NULL | VIRTUAL GENERATED | +---------------+---------+------+-----+---------+-------------------+ 4 rows in set (0.00 sec) mysql> Insert into profit(Cost, Price) values(100,110); Query OK, 1 row affected (0.04 sec) mysql> Insert into profit(Cost, Price) values(200,220); Query OK, 1 row affected (0.04 sec) mysql> Select * from profit; +------+-------+--------+---------------+ | cost | price | profit | price_revised | +------+-------+--------+---------------+ | 100 | 110 | 10 | 108 | | 200 | 220 | 20 | 218 | +------+-------+--------+---------------+ 2 rows in set (0.00 sec)
