so all users can to send at once to Rome ))

UPDATE user u SET u.address = 'Urupinsk'
update and delete is an insidious thing, if not to prescribe where and check select-Tom! - julien_Altenwerth commented on June 5th 19 at 21:09
we have a brain , and if it is used then all will be OK.)))
The challenge is to make ONE value in all cells of the column. What can I check?

PS In production I always do bakapy before performing any operation on the database, except backups of the cron daily. - jerrold_Hickle commented on June 5th 19 at 21:12
There's nothing you need to check.
But in all other cases, when used in update and delete is better to keep an eye on, even if there is backup on the backup to finish select easier than to carry out restoration activities. - jerrold_Hickle commented on June 5th 19 at 21:15
who can argue? - Camryn.Schimmel commented on June 5th 19 at 21:18
