Hi all:
I am encountering a following situation:
- one developer is executing alter table T1 disable foreing key FK1. The
FK1 is referrting to a table T2 as a parent table
- another developer is holding a lock on the T2
The first developer's command is stuck until the second one releases the
lock. I have seen it several times today
Why does this happen? I would understand that an ENABLE command would be
affected by that, but why would
a DISABLE command be affected?
thank you
