Re: SQL: UPDATE values in two tables at once

Hello Kevin,

I usually use where exists because I'm used to it, but I think there are better ways out there. Something like this maybe.

Thank you very much!

update table 1 set table1.status = 'Old'
where table1.stamp <= (select table2.alert from table2)
and exists (select 1 from table2 where table1.id = table2.id)

I struggle to incorporate the date calculation.


UPDATE table1 SET table.status='Old'
WHERE table1.stamp <= DATE(CURRENT_TIMESTAMP) - (
SELECT table2.alert FROM table2
) days AND EXISTS
(
SELECT 1 FROM backupmon.configpf
WHERE b_statuspf.id=configpf.id
)

This one is not throwing a syntax error but complaining that the result of the statement yields more than one line. Hmm.

Any hints?
