Обсуждение: change data type 'money' to '€'

Hello

In our project table we have a column with costs, using data typ
"money". By default PostgreSQL always applys '$', but we would like to
have '€'.
How can I change the data type "money" (currency) of a column in an
existing table to '€'?

Thanks a lot!

It is locale specific thing, defined in variable lc_monetary. If your
locale uses $, it will display $. If you want to display EUR instead,
you will need to set lc_monetary to the country using euros (say, Germany).

You may set lc_monetary in postgresql.conf, or within your sql client.
Here is the latter test case:

create table money_test (
   m money not null,
   primary key(m)
);
insert into money_test values ('123');
set lc_monetary="de_DE@euro";
select * from money_test;

This is not such a good idea to use currencies' shortcuts, specially if your
program is to be internationalized or used with another currency (eg: there's
no shortcut for Swiss Franc) - for these reasons, you'd better use 3 letters

See the lc_monetary setting (you'll need to have an installed system
locale setting that does what you want).
