Oracle Show Space Procedure
This PL/SQL procedure displays free and unused space information for a specified database object (such as a table). It uses the DBMS_SPACE package to retrieve storage statistics including free blocks, total space, unused space, and last used extent details, then prints the results using DBMS_OUTPUT.
