Question

我的要求是更新已分区表格的partition_date列 - MYTABLE。我有MYPROC pl / sql程序来执行此操作。以下是MYPROC的相关内容。

p_partition_name VARCHAR2(40);

SELECT distinct(uo.subobject_name)
INTO p_partition_name
FROM MYTABLE  t,
  user_objects uo
WHERE dbms_rowid.rowid_object(t.rowid) = uo.object_id
AND partition_date BETWEEN '01-OCT-2015' AND '31-OCT-2015';



BEGIN

                         DBMS_OUTPUT.PUT_LINE('Partition Name' || p_partition_name);
                           FOR i IN 1 .. partition_table.count
                             LOOP
                                UPDATE MYTABLE partition (p_partition_name) SET PARTITION_DATE = '01-AUG-2015' WHERE {..some condition..}
                             END LOOP; 
                      END;

当我执行MYPROC时，我得到以下错误。

Error report:
ORA-02149: Specified partition does not exist
ORA-06512: at "NESSDBA.MYPROC", line 116
ORA-06512: at line 2
02149. 00000 -  "Specified partition does not exist"
*Cause:    Partition not found for the object.
*Action:   Retry with correct partition name.
Partition NameSYS_P3495

当我在不使用过程的情况下发出以下普通update语句并手动传递分区名称时，没有错误。

UPDATE MYTABLE partition (SYS_P3495) SET PARTITION_DATE = '01-AUG-2015' WHERE {..some condition..}

如何将分区名称传递给pl / sql中的更新语句？

尝试使用动态sql而不是static; 请在下面找到代码，

declare
v_date  date:= to_date('01-AUG-2015','dd-mon-yyyy');
bEGIN
  FOR i IN (SELECT distinct (uo.subobject_name) partition_name FROM parttab t, user_objects uo
     WHERE dbms_rowid.rowid_object(t.rowid) = uo.object_id) LOOP

    DBMS_OUTPUT.PUT_LINE('update parttab partition (' || i.partition_name || ') set jdate = '||v_date );
    execute immediate 'update parttab partition (' || i.partition_name || ') set jdate = :vv_date' using v_date;

  END LOOP;
END;
