Need some direction on how best to program the following:
I have two tables "MASTER" and "TRANSACTION"
TRANSACTION field MID is linked to MASTER ID Field MID
MASTER Table contains MID, Description and 12 columns "Jan" Feb".. etc, each representing expenditures for each month of the year.
TRANSACTION table contains MID, Transaction Date and Transaction Amount
I need to:
1. zero out each month column in each row of Master Table
2. read each Transaction Row and add it's Transaction Amount to the proper month column in the related MASTER Table Row.
