Oracle Solution for Error ora-14099

ORA-14099: all rows in table do not qualify for specified partition

What triggered the Error:

There is at least one row in the non partitioned table which does not qualify for the partition specified in the ALTER TABLE EXCHANGE PARTITION

What should we do to fix it:

Ensure that all the rows in the segment qualify for the partition. Perform the alter table operation with the NO CHECKING option. Run ANALYZE table VALIDATE on that partition to find out the invalid rows and delete them.
