Re: numeric data type

Numeric and Integer type are exactly that - numbers.

If you want to _store_ it in the data with the leading 0, then you need to
change the type to a varchar, then put a check constraint on the field to
ensure that each of the 2 characters are numeric.

Alternatively, you can leave it as a numeric / integer and add the leading 0
as part of the queries that access it. Let me know if you want an example
how to do it.

Subject: [NOVICE] numeric data type

I've got the following:

cc_exp_month numeric(2,0)

So that I could input '06', for instance -- however the 0 doesn't make it's
way into the column... I get '6' instead.

I want to constrain this in the db, which is why I don't just use:

cc_exp_month integer

My question: what do I need to do to have the constraint ( two digits )
work,
while still keeping the extra 0?

Thanks.
