Question

Hi I need to resolve next problem.

I have a row in mysql:

‘start_at’ and ‘ends_at’

They are Timestamps type.
I need to set default value of ends_at plus 7 days from starts_at

something like this:

ALTER TABLE `a_to_b`
MODIFY COLUMN `ends_at`  timestamp NULL DEFAULT 'CURRENT_TIMESTAMP + 604800' AFTER `starts_at`;

If i am right in MSSQL i can do DATE_FROM();
How can I do this in MySql?

Thanks.

mysql does not allow computation in table structure. You need to do the insert afterwards:

insert into myDate (endTime) values ((interval 7 day + current_timestamp))
