isnot supported.
I'm not convinced I understand what your query would do, but it sounds as
if you need to use GROUP BY. For example:
lfix=> select custid, count(custid) from invoice group by custid;
custid |count
--------+-----
ACECS | 1
ADG | 8
FALKIRK | 1
JEFSYS | 25
SOLPORT | 15
(5 rows)
lfix=> select count(*) from invoice;
count
----- 50
(1 row)
Is that what you want to achieve?
