>I am trying to create a view, which among others, has 4 fields- Date, Debit, Credit, and Balance-(which is the present running cash balance). For the Balance, it requires the (sum of all credits)-(sum of all debits), but only upto that date, or entry. My problem is, that when I specify it that way, I get only one row in the view, showing the total of all debits and all credits for the entire table. Could someone help me with this one ? Thanks.

Try:
SELECT Date, Debit, Credit,;
       NVL(SELECT SUM(Credit-Debit) FROM MyTable Tbl1 WHERE Tbl1.Date < MyTable.Date), CAST(0 AS N(12,2)) AS Balance;
       FROM MyTable
