what is the difference between [select single xxx from ...]
and [select * from ... up to one row]?
Answer Posted / harsha
upto one row is faster than select * from
select single xxx from xxx into wa xx = xxx-xx means it will check all the fields and finally gives a first possible record in the selected group of record
select * from xxx in wa where xx-xxx upto one row means it retrieves only first possible record of table satisfying th condition.
please revert me if any issues with this answer. i dunno weather its ryt r rong.
