ByHaakon RobertsandJudy Tobias. Before Db2 Version 5,table columns that were in a partitioning index could not be updated. Since Version 5, the columns were updateable intables that were created in Version 5 or later, but the partitioning key columns in older tables remained non-updateable.You needed to use an awkward and time-consuming procedure, such as unloading the data, dropping the table, recreating the table, and reloading the data, to make the columns updateable.
You now havemuchbetter alternatives. If you performoneof these operations, Db2 automatically makes the columns updateable:
In Db2 11 or Db2 12, convert the table spacefrom index-controlled partitioning to table-controlled partitioning
In Db2 11 or Db2 12, convert the table space toapartition-by-range table space
In Db2 12, convert the table space from a partition-by-range table space with absolute page numbering to a partition-by-range table space with relative page numbering
To take advantage of these changes, before you convert your table spaces, apply the relevant PTFs, based on your version of Db2:
