alter table segment

A partitioned table was created such that the default tablespace is USERS, but the partitions are to go into tablespaces called DATA_1 for partition 1 etc.  Now a generic program that tries to create new partitions tries to create new partitions as USERS_2 rather than DATA_2.

From the manual it appears that I can change the default tablespace with a segment attribute clause, but I find such a statement fails.

Would: alter table A move tablespace DATA solve the problem without impacting the partitions?

Any suggestions.

DB is 11gR2.

Thanks,
