This is a repost of a question which still confuses me.
I wish to write a function that returns NUM_ROWS for a particular
condition AND a subset of those rows (eg by using LIMIT and OFFSET).
I imagine having function b that returns a reference to a cursor and
NUMROWS. In function a I use the cursor to effectively do the LIMIT and
OFFSET, and append the NUM_ROWS column to all of the results.
Is this sensible, efficient, feasible? I have not used cursors before.
Or should I simply do 2 separate functions, 1 for NUM_ROWS, the
other for the result set I want?
Help much appreciated!
