      Hello Muneer,
      Thanks for reply,Kindly tell me query to find out Tablespace free(MB,G) and used space along with it’s datafile.

        SQL> select TABLESPACE_NAME,round(sum(BYTES/1024/1024),2) FREE_SPACE_MB, round(sum(BYTES/1024/1024/1024),2) FREE_SPACE_GB from dba_free_space group by TABLESPACE_NAME;

        Dear Umair, the above query involves a group function, so you can not select the datafiles with tablespaces. For that, you can separately query the datafiles for various tablespaces from dba_data_files view.
