  • Handling NULL value on Update

    I'm updating several values in an existing table that does not allow NULL values. This is the "abridged" SQL statement (embedded in RPG).

    Code:
           Update MYORDERS set
           BOOK_MTD = (select sum(ord_amt) from ORDERS where 
             ord_date>=:beginMonth and ord_date<=:endDate) ,
           BOOK_YTD = (select sum(ord_amt) from ORDERS where 
              ord_date>=:beginYear and ord_date<=:endDate),
           Where YEAR = 2019;
    If the SUM(ord_amt) is NULL, the update fails with Sql State: 23502 Sql Code: -407

    Is there a way to specify an update value of zero(0) instead of NULL?

      ifNull() also works.
