Modify Messaging to Clarify Why a Table Is Being Dropped and Recreated

When reading the output from the compare portion of Alter reports, it isn't always clear what part of a change requires a drop and recreate of objects.  We are making a change to a column from NOT NULL to WITH DEFAULT NULL,  and the wording isn't really clear that this change to the columns is resulting in the dropping and recreation of the objects involved. Our DBA making this change reviewed this and thought that the table being partitioned was the reason for the drop and recreate:

 

Compare tablespace source(PENMNA00.MACNTRH) and target(PENMNA00.MACNTRH)
No changes to Tablespace

Compare table source(DB2.MA_CNTR_H) and target(DB2.MA_CNTR_H)
Column MA_STAT_CD
(D)Nulls/default changed from NOT NULL to WITH DEFAULT NULL
Column MA_SVC_PRVDR_CD
(D)Nulls/default changed from NOT NULL to WITH DEFAULT NULL
Tables have identical column lists
Table DB2.MA_CNTR_H is partitioned and will be dropped by dropping tablespace PENMNA00.MACNTRH
Table will be recreated
Table data will not be converted
Not eligible for FORMAT INTERNAL processing

 

It would be nice if the first few lines read something more like this to help make it more obvious that changing the attributes on the column(s) is resulting in the drop/recreate of objects:
Column MA_STAT_CD
(D)Nulls/default changed from NOT NULL to WITH DEFAULT NULL
Table will be dropped
Column MA_SVC_PRVDR_CD
(D)Nulls/default changed from NOT NULL to WITH DEFAULT NULL
Table will be dropped

Thanks-
