No offence. I was trying to help but first I needed more information.
There could have been more than one reason why you'd want to do this -
for example you could have had a requirement to integrate the data with
an external application.
The reason I ask about MONEY in particular is that the problems with
using that datatype in calculations may sometimes be overlooked. Take a
look at the following example. Be aware of the rounding issue when you
develop calculations against the data and think carefully about the
implications before you use MONEY.
DECLA RE
@mon1 MONEY,
@mon2 MONEY,
@mon3 MONEY,
@mon4 MONEY,
@num1 DECIMAL(19,4),
@num2 DECIMAL(19,4),
@num3 DECIMAL(19,4),
@num4 DECIMAL(19,4)
SELECT
@mon1 = 100, @mon2 = 339, @mon3 = 10000,
@num1 = 100, @num2 = 339, @num3 = 10000
SET @mon4 = @mon1/@mon2*@mon3
SET @num4 = @num1/@num2*@num3
SELECT @mon4 AS money_result,
@num4 AS numeric_result
Result:
money_result numeric_result
