// lookup table space file location

select tablespace_name, file_id, file_name,round(bytes/(1024*1024),0) total_space from dba_data_files order by tablespace_name

 

// Add the statement table space

The ALTER TABLESPACE tablespace name the ADD DATAFILE
 ' + datadg / ORCL / datafile / SP07_05.dbf ' SIZE 30720M; 


- - file path tablespace '+ DATADG / orcl / datafile /               SP07_05.dbf'

 

 

Create a new table space and a new user instances:

create TABLESPACE  ssdev  DATAFILE
'E:\APP\WUJJ\ORADATA\ORCL\SSDEV.DBF' SIZE 100M;

create user ssdev identified by wujingjun default tablespace ssdev;

grant connect,resource to ssdev; 
grant create session to ssdev;
