Re: Number of rows in a cursor ? - Mailing list pgsql-sql

You cannot count the number of rows in a cursor, unfortunately. I recently ran in to this problem.

As far as I am aware, the only way to count them is to either iterate through them,
or if you are only expecting one or two, perform multiple FETCHES and test if the
record set returned is empty.

OPEN cur_overlap FOR EXECUTE 'SELECT *, ....';

FETCH cur_overlap INTO row_one;
FETCH cur_overlap INTO row_two;
       IF (row_two.id IS NULL) THEN ....
