Обсуждение: remove $ from money field

Should be a simple question.

When selecting a field that is of type money, how can I remove the $
when selected?

example: $10.00 would return as 10.00

money as a datatype is deprecated, use numeric(9,2) instead (or whatever
precision you need).

Datatypes:

Actually, almost the only thing money does for you is put in the $ sign
;-).  I'd recommend using type numeric instead, if you have any desire
for more flexibility.

As others have said, money is deprecated. I used this function to
migrate some money data once; you could use it to reformat data if you
wanted.

CREATE OR REPLACE FUNCTION x_money(money) RETURNS decimal AS '

    set moneydata $1

    regsub -all {[,$]} $moneydata {} workable

    return $workable
