For example I have transaction

From 2006 – 2012

I want to read all and generate separate QVDs by month and year by a loop in the script.

Don’t know how

Something like this should do the trick (adjust field names as required):


For zYear = 2006 To 2012
     For zMonth = 1 To 12
         Let zMinDate = Date(MakeDate(zYear, zMonth, 1));
         Let zMaxDate = Date(AddMonths(zMinDate, 1) - 1);
         Let zFileName = 'Transaction_' & zYear & Month(zMinDate) & '.qvd';
         Transactions:
         LOAD TransactionDate,
              TransactionTime
              ...
          From ...
          Where TransactionDate >= '$(zMinDate)' And TransactionDate <= '$(zMaxDate)';
         STORE Transactions Into [$(zFileName)] (qvd);
          DROP Table Transactions;
     Next
Next

This assumes that the default date format in your QV model is the same as the format in your transaction source.

You may wish to try something along these lines:

AllData:
SQL SELECT * FROM <Source>;

YearList:
LOAD DISTINCT <Year-Field> as SaveYear
RESIDENT AllData;

LET vNumYears = NoofRows ('YearList');

SET ii = 0;

FOR ii = 0 to $(vNumYears) - 1

LET vSaveYear = peek ('SaveYear', ii, 'YearList')

Temp:
LOAD *
RESIDENT AllData
WHERE <Year-Field> = $(vSaveYear);

STORE Temp INTO Data-$(vSaveYear).qvd;

DROP TABLE Temp;
