Has there been any discussion regarding adding a time-limited version of NOWAIT, say:
“WAITONLY 50” (milliseconds), when dealing the explicit LOCK TABLE or the
SELECT…FOR(SHARE|UPDATE) commands?
is this a feature in any other major databases?
Yes, at least Informix has it in the form of SET LOCK MODE TO { NOT WAIT | WAIT [N] }.
is this in the sql spec?
No.
what do you expect to happen if these timeouts expire? return an error, and abort the
transaction?
