I have an app that does essentially the following query:
SELECT host(netblock),masklen(netblock),netblock,netmask(netblock)
FROM networks
WHERE status=get_status_code('available') AND parent_asn=4278 AND masklen(netblock)=xx -- where xx is a legit mask
size
FOR UPDATE
LIMIT 1;
inside a BEGIN TRANSACTION block.
My question is:
if a 2nd copy of this query runs with the same size, will it skip the
locked row, or wait for commit?
