TRY THIS SQLCOMMAND

SQL

update mytable set dept =(select max(dept) from mytable )+1 where ID= (SELECT MIN(ID) FROM MYTABLE WHERE DEPT IS NULL) AND dept is Null

RUN IT IN A LOOP CONTAINING THE COUNT OF THE NULL VALUES.

It's Just Incrementing the Next value...But I need Separate Increment for A1,A2,A3 By selecting Max value
