I was wondering if someone could shed some light on money fileds for me. I
am having a problem in that a money field plus a null money field equals
null. Try this:
create table test(total money);
insert into test values('');
insert into test valuse(NULL);
select * from test;
select '1'::money + total from test;
Why is the second column blank? This is really throwing my calculations
because there are times when $0.00 is different from no value at all.
Also, how can I get a query of all rows where the money value is NULL?
select * from test where total = NULL;
ERROR: parser: parse error at or near "null"
and this gives me the rows with $0.00:
select * from test where total = '';
If I can't query for a money field with a NULL value, why can I insert one?
