Re: simple sql question/mlml

how do you want your output formatted? did you want each transaction listed with the periods like:

"amount period1 period2 period3"
"amount period1 period2 period3"
"amount period1 period2 period3"

or like this:
"amount period1

        period2
        period3
 amount period1
        period2
        period3"

are the number dates in the transaction row fixed or variable?
