What is wrong with my query? I had look here but could not resolve the problem.
SQL> CREATE TEMPORARY TABLESPACE TEMPRM;
Tablespace created.
SQL> ALTER TABLESPACE TEMPRM ADD DATAFILE '+TEMPDATA/rm/datafile/TEMPRM_temp01.dbf';
ALTER TABLESPACE TEMPRM ADD DATAFILE '+TEMPDATA/rm/datafile/TEMPRM_temp01.dbf'
*
ERROR at line 1: ORA-03217: invalid option for alter of TEMPORARY TABLESPACE
