When I'm running a SQL with multiple occurrences of a bind variable with F9:
SELECT &1+&1+&1+&1+&1+&1+&1+&1 FROM DUAL;
...Toad dutifully pops up the Variables window, but shows a separate variable entry for each occurrence. Shouldn't this just be a single replacement? Subsequent runs of the same SQL automagically substitute the last value of the first occurrence for each.
Or am I using this wrong? Which is not only possible, but probable.
