Can someone suggest what field is best to use and the best way to handle and store and create currencies fields. But there will be various currencies there (USD, JPY, etc.)

Also, is there some special way to handle GMT times?

Thanks!

Dear,

The for money I suggest decimal, I don't know the precision of the decimal that you want. Most of the time two decimals it's ok.

For GMT times, I would use timestamp that it's in GMT too.

Regards

Would something like this work for price?

PriorOpen` decimal(45) NOT NULL DEFAULT ''

and how about for the GMT time:

`DateGMT` timestamp(45) NOT NULL DEFAULT '',

please make sure you don't mix up stuff.

30.3$  is 2 things, looking at it a normalized way:
* 30.3  amount, which is decimal
* $     currency, which can be stored in a dedicated field with either
    - USD  : it's iso code (recommended)
    - $  :  it's visual representation
    - xxx: some other lookup key value, for example a numerical key which is the fk for another table that stores the currencies used

if you stored litterally '30.3$' in a string/text field, you will end up with nothing but problems when you need to do SUM( ) or similar math stuff with the amount, or currency conversion(s) to other currencies.
