Hi Steve,
Have you tried converting to a decimal type or cast for the cost
field? If you
are gathering this data from a text field and placing in a variable
of type string
then using that variable in the insert statement it may be rejected
because it is not
type decimal. This has been my experience with trying to get input
data from
user's textfields and placing in the db.

Thanks Steve,
Actually I do not insert text data into my numeric field.
As I mentioned given
create table t1 { name text, cost decimal }
then I would like to insert numeric data into column "cost" because
then I can later benefit from numerical operators like SUM, AVG, etc
More specifically, I am using HTML, Perl and PG. So from the HTML
point of view a textfield is just some strings. So my user would
enter 12345 but expressed in UTF8. Perl would get this and use DBI to
insert it into PG
What I am experiencing now is that DB errors that I am trying to
insert an incorrect data into column "cost" which is numeric and the
data is coming in from HTML in UTF8
Mybe I have to convert it to ASCII numbers in Perl before inserting
them into PG
Thanks
Medi

Hi Medi,
I have only limited experience in this area, but it sounds like you
sending your numbers as strings? In your example:
>create table t1 { name text, cost decimal };
insert into t1 (name, cost) values ('name1', '1');
I can't think of how else you're sending numeric values as UTF8? I know
that Pg will accept numbers as strings and convert internally (that has
worked for me in some object relational environments where I don't
choose to cope with data types), but I think it would be better if you
simply didn't send your numeric data in quotations, whether as UTF8 or
ASCII. If you don't have control over this layer (that quotes your
values), then I'd say converting to ASCII would solve the problem. But
better to convert to numeric and not ship quoted strings at all.
I may be totally off-base and missing something fundamental and I'm
very open to correction (by anyone), but that's what I can see here.
Best regards,
Steve
