sql - Why grouping in a subquery causes problems -
When I include lines of 2 in the following subquery, it seems that this is my Sybase 12.5 ASE server then As long as there are no results, it continues till all time. The query runs fine without these 2 lines. How wrong is that grouping?
to show the explanation Does.
In this case, can not you end the sub-division by making it part of the main question?
