CREATE UNIQUE INDEX xtab1 ON tab1 (c1) include (c2)B
CREATE UNIQUE INDEX xtab1 ON tab1 (c1); CREATE INDEX xtab2 ON tab1 (c3) INCLUDE (c2) C
CREATE UNIQUE INDEX xtab1 ON tab1 (c2, c1)D

单选题If the ADD DBPARTITIONNUM command is used to add a new database partition to an existing DB2 instance,which statement is correct? （）A
All existing databases in the instance are expanded to the new database partition but data cannot be stored on the newpartition until it has been added to a partition group. B
Database partition groups within existing databases will automatically include the new database partition and willredistribute their existing data to the new partition. C
Any single partition databases within the instance will automatically become multi-partition databases once the newpartition is added to the instance. D
A database administrator would need to modify the db2nodes.cfg file to complete the addition of the new partition tothe instance.
