Thread: Money variable

I am attempting to enter values for a database used by the book "The
Practical SQL Handbook," (Bowman, et.al, Addison-Wesley, 1996).

This book, using SQL Anywhere, uses a "bookbiz" database, with a "titles"
table.   "Tables" includes, among other things, two fields "price" and
"advance" which use the money variable.  I am attempting to enter this data
into Postgres.

I cannot enter data into these fields in Postgres.   When entering "$20.00"
for price I get the following:  "error near '.00'.  When entering "$20" I
get "out of range." and when entering "20.00" I get " attribute 'price' is
of type'money' but expression is of type 'float8'.  You will have to rewrite
or cast the expression.

I have drooped and re-created the table.  I have attempted to enter this
data numerous times.  No luck.

How do I enter money data in Postgres?

Money is not recommended (deprecated). The recommended method is to use
NUMERIC with a two-digit precision (or three, in countries where relevant,
which is exactly why this recommendation was made).

But if you insist on using money for the sake of the example, you should
put the values in single quotes, like strings:

INSERT INTO money_table (money_field) VALUES ('20.00');
