Re: Unable to get Last Record..
Thank you so much, Peter!
// This returns an error, stating [[You can't specify target table 'd' for update in FROM clause]]
update tdds.discrete_data d
set d.dd_auto_purge=1
where d.dd_acquired_ts < (
SELECT Max(dd_acquired_ts)
FROM tdds.discrete_data
where dd_acquired_ts < 1493152486000
)
ORDER BY d.dd_acquired_ts asc
LIMIT 100000;
Wouldn't it be something like this? it doesn't return an error, but extremely slow..
update tdds.discrete_data d
set d.dd_auto_purge=1
where d.dd_acquired_ts < (
SELECT Max(d.dd_acquired_ts)
FROM tdds.discrete_data d
where d.dd_acquired_ts < 1470316338269
ORDER BY d.dd_acquired_ts asc
LIMIT 100000) ;
Please advise.
