    we have command to release the unused space from the tables and resizing of the tablespaces. there is no delete unused space command either in alter tablespace or alter table commands

    Where did you get 'delete unused' from ??
    Did you try and research the statement.

    Pando is correct in his syntax.
    The command is used if an extent has been given to a segment which is larger than needed.
    Once you have eliminated all of the impossible,
    whatever remains however improbable,
    must be true.

    Hi,

    When should we use this command? What are the advantages?

    Thanks,
    Sam
