forall 与 for loop 案例

create table a_tab(ver number,id number);
create table b_tab(ver number,id number);
set timing on
DECLARE
l_add INTEGER:=0;
BEGIN
FOR i in 1..200000 LOOP
l_add:=l_add+i;
EXECUTE IMMEDIATE 'insert INTO a_tab values(:a,:b)' USING i,l_add;
END LOOP;
COMMIT;
END;
/

DECLARE
v_sql VARCHAR2(4000);
v_tablename VARCHAR2(100) := 'b_tab';
BEGIN
v_sql :='
DECLARE
TYPE r_outtab is RECORD (ver NUMBER,id NUMBER);
TYPE t_outtab is TABLE of r_outtab INDEX by BINARY_INTEGER;
v_outtab t_outtab;
v_query VARCHAR2(30000);

v_query := ''SELECT ver,id from a_tab '';
EXECUTE IMMEDIATE v_query bulk collect INTO v_outtab;
forall i in v_outtab.FIRST .. v_outtab.LAST
INSERT INTO '|| v_tablename ||' VALUES v_outtab(i);
END;';
DBMS_OUTPUT.PUT_LINE(v_sql);
EXECUTE IMMEDIATE v_sql;
COMMIT;

---forall 中使用execute immediate动态执行则报错。原因为非sql类型，动态PLSQL,但本人在11.2.0.3中运行并没有报错，记录下。

ERROR at line 12:

PLS-00435: DML statement without BULK In-BIND cannot be used inside FORALL
/*表名动态，后面全要拼凑，因为那个集合是非sql类型的集合，无法拼凑的，用||是不行的，用using当然也不行，using必须要求sql类型*/
