Thread: Convert numeric to money
Hi. I have searched in mailing-list archives about converting types, but I couldn't found a function or clause that convert a numeric type to money type. How Can I convert this types? => select '1234'::money; money ------------R$1.234,00 => select '1234'::numeric::money; ERROR: cannot cast type numeric to money The problem is becouse I have a table with "numeric" field, and I need to show it like "money" type (R$ 1.234,00). Is there a function to convert it??? Or is there a function to mask the numeric field to show like money (with R$x.xxx,xx)??? Thanks.

You probably want to use to_char to convert the numeric value to a string which can be displayed.
inspect your cast functions with:
create view showcasts as select t.typname as source, t1.typname as target, p.proname as function, (select case when
c.castcontext= 'e' then 'Must use Explicit Cast' else ( select case when c.castcontext = 'i' then
'Implicitcast for expressions and assignments' else 'Implicit cast only for assignments' end)
end) as casttype from pg_cast c, pg_type t, pg_type t1, pg_proc p where c.castsource = t.oid and c.casttarget =
t1.oidand c.castfunc = p.oid;
Un saludo.

You probably want to use to_char to convert the numeric value to a string
