Try this

DELETE FROM custinfo
WHERE
custinfo.UserID = custinfotemp.userid AND
custinfotemp.updateStatus = 'D';

It would be good to have indexs on UserID on both tables.

Seeing a table named "custinfotemp" kind of raises a red
flag. Possibly you may want to re-think the design if
you are moving data between tables that is really the
same data.
