forall中使用buLK

报错：
SQL命令为正确结束
定位在13行


FORALL i IN 1 .. ename_table.count
EXECUTE IMMEDIATE sql_stat USING ename_table(i)
RETURNING BULK COLLECT INTO sal_table;
这个语句的使用 有什么问题嘛？

代码如下：


SQL> select ename, sal, sal*1.1 new_sal from emp where ename in('SCOTT', 'SMITH', 'CLARK');

ENAME            SAL    NEW_SAL
---------- --------- ----------
SMITH         800.00        880
CLARK        2450.00       2695
SCOTT        3000.00       3300

SQL> DECLARE
  2    TYPE ename_table_name IS TABLE OF emp.ename%TYPE;
  3    TYPE sal_table_name IS TABLE OF emp.sal%TYPE;
  4    ename_table ename_table_name;
  5    sal_table   sal_table_name;
  6    sql_stat    VARCHAR2(200);

  8    ename_table := ename_table_name('SCOTT', 'SMITH', 'CLARK');
  9  
10    sql_stat := 'update emp set sal=sal*1.1 where ename=:1 returning sal into :2';

17      dbms_output.put_line('employee: ' || ename_table(j) || ' New salary: ' || sal_table(j));
18    END LOOP;
