I'd say storing and converting doesn't matter much, but currency
amounts are often summed up (say for a monthly report over a huge
table). For this INT should be a big win.

are less than before, and comparisons are faster.
Either way, do you have a feel (or access to any studies) for the
impact of using DECIMAL instead of INTEGER for currency? I'd just
wonder if it's enough to make up for all the required conversions

Hello,
I am seeking to create a table to hold prices for products. I am not sure what
type would be best. According to the docs, I have many choices, dec, double,
float, etc. Can anyone give me an idea, of which is the proper choice for
handling US currency like so: 1500.99

I can't imagine any reason to use a type other than DECIMAL for a
currency value.
A reason could be performance. Storing cent values in an INT field is
more efficient.

Are you saying that storing and/or retrieving a DECIMAL value takes
appreciably more time than an INTEGER

My final issue is inserting a currency, $500.00 for example into a field
that is a BigDecimal(10,2).
Anyone have any thoughts on how to do that within a SQL statement?

Just convert the format of the input in your program before saving the value. In
VB/ASP us can do: replace(255,55,,,.)

I am guessing that you are trying to find a MySQL data type of Currency,
which does not exist.
I generally use a column that is DECIMAL(150,2) for US currency.

Any hints on this one?

I normally use the DECIMAL(6,2) data type, works very for currency values.

For currency, it depends on your use of course, but fixed-point is
usually easiest. Where you fix the point depends on the precision
you require.
For display purposes it is easiest to use the smallest currency
unit as an integer (e.g. cents). For conversions, daily interest
