TRUNCATE not releasing space from the table
(Doc ID 2277666.1)
Last updated on AUGUST 04, 2018
Applies to:Oracle Database - Enterprise Edition - Version 184.108.40.206 to 220.127.116.11 [Release 9.2 to 12.2]
Information in this document applies to any platform.
When we delete the rows from the table using the DELETE command, the extents that are allocated to the table will not be released and the table still holds them, whereas when using TRUNCATE with DROP STORAGE clause (which is default), it will release the space back to tablespace.
But we see cases that event truncating won't release the space back to tablespace.
