To add minutes to a datetime, you can use the DATE_ADD() function in MySQL. In PHP you can use strtotime().
To add 30 minutes in MySQL, the DATE_ADD() function is as follows -
select date_add(yourColumnName,interval 30 minute) from yourTableName;
In order to use the above syntax, let us create a table. Below is the query to create the table.
mysql> create table Add30MinutesDemo −> ( −> YourTime datetime −> ); Query OK, 0 rows affected (0.67 sec)
Insert records in the table with the help of the following query -
mysql> insert into Add30MinutesDemo values(now()); Query OK, 1 row affected (0.21 sec)
Display the records in the table with the help of select statement. The query is as follows -
mysql> select *from Add30MinutesDemo;
The following is the output -
+---------------------+ | YourTime | +---------------------+ | 2018-12-07 18:03:51 | +---------------------+ 1 row in set (0.00 sec)
This is the MySQL query to add 30 minutes to the column. The query is as follows -
mysql> select date_add(YourTime,interval 30 minute) from Add30MinutesDemo;
The following is the output -
+---------------------------------------+ | date_add(YourTime,interval 30 minute) | +---------------------------------------+ | 2018-12-07 18:33:51 | +---------------------------------------+ 1 row in set (0.00 sec)
