From here, you can select your desired partition table type. The new disk label will have no partitions. Other users can access the table, and read, and modify data from there. The RANGE partitioning type is used to assign each partition a range of values generated by the partitioning expression. Only choose MBR for compatibility if you need it. Alternatively you can plug the disk drive (that is to be converted for partition table type) as an external disk drive to computer and proceed with the conversion. For the same reason, we will search with additional condition of object type, which will list only user created tables. The basic compression described here is a free feature in the Enterprise Edition of the database.
