How to Create a Synonym on a Table Partition (Doc ID 119805.1)

 

How to Create a Synonym on a Table Partition:=============================================You cannot directly create a synonym on a table partition by specifying the partition name and table name with the CREATE SYNONYM command.  You have to create a view on the partition, and then create a synonym on the view.  This is a two-step method instead of a single-step method.Follow the steps in this example to create the synonym: $ sqlplus scott/tiger SQL> create table emp_pt      ( empno number primary key,        ename varchar2(30))      partition by range (empno)      ( partition p8000 values less than (8001),        partition p9000 values less than (9001),        partition p10000 values less than (10001),        partition pothers values less than (99999999)); SQL> insert into emp_pt      select empno, ename from emp;        --- Populated the partition table EMP_PT with existing        --- data from the EMP table. SQL> commit; SQL> select * from emp_pt;      EMPNO ENAME      ----- -----------------      7369  SMITH      7499  ALLEN      7521  WARD      7566  JONES      7654  MARTIN      ...      9999  ANDY SQL> select * from emp_pt partition (p8000);      EMPNO ENAME      ----- ---------------------      7369  SMITH      7499  ALLEN      7521  WARD      7566  JONES      7654  MARTIN       ...      7934  MILLER SQL> create view emp_pt_p8000 as select * from emp_pt partition (p8000); SQL> desc emp_pt_p8000       Name                                Null?
