Hi,

 

why not simply add a before insert trigger, that calculates and inserts the
new current number.

Something like this:

 

Create Trigger MyLib/InsCurrNbr

       BEFORE INSERT on MyFile

       Referencing NEW as INS

       For Each Row

       Mode DB2ROW

   Select  Coalesce(Max(a.CurrNbr) + 1 , 1)

      into INS.CurrNbr

      from MyFile a

      where a.Key = INS.Key;

 

With a  Before Insert Trigger the current number is always calculated and
inserted in the record, when a new record is added to the file.

Independend from the used interface (Native I/O, UPDDTA, Interactive SQL
...)

 

 

Mit freundlichen Grüßen
