    ****************************************************************
    When a user deletes multiple columns in the middle of the
    table, and then adds multiple columns in the middle of the
    table, the position for the newly added column is incorrect
    in the CNC file, which will cause DB2 to load unexpected
    content to the newly added column.
    

Problem conclusion

  • Program has been changed to calculate the position for the
    newly added column based on the last position of the existing
    column to make sure there is no content reloaded to the newly
    added columns after the ALT.  The following is an example:
    
    LOAD DATA INDDN SYSREC   LOG NO  RESUME YES
    EBCDIC  CCSID(00037,00000,00000)
    ENFORCE NO
    INTO TABLE ">TB_SCHEMA<"."TB_NAME"
    WHEN(00001:00002) = X'0003'
    NUMRECS                    8
       (
        CRA     POSITION(3:4)
          DECIMAL  PACKED  ,
        COD_ALLEGATO    POSITION(5:8)
          DECIMAL  PACKED  ,
        NEWCOL1   POSITION(22:22)
          CHAR    (    1)  ,
        NEWCOL2   POSITION(23:24)
          VARCHAR
       )
