I like to have what I call “baby sitting” messages such as “Completed 15 out of 1023”. To do this, I need the number of results a query returns but I also need the results.
Currently I’m doing this with two queries such as:
SELECT COUNT(*) FROM table WHERE …. expression …
SELECT * FROM table WHERE …. expression …
But this requires two queries. Is there a way to do the same thing with just
one query somehow?
I’ve been toying with row_number() and then sort by row_number descending and
pick off the first row as the total number. The problem is that mucks with the
order of the original query because of the sort on row_number. I’ve even
thought about reversing the order and then reversing the order a second time
but that seems to be getting more than a little absurd.
Thank you for your time,
Perry
