Question

我有以下代码，我尝试使用forall进行插入：

DECLARE

START_TIME NUMBER;
END_TIME NUMBER;

CURSOR INSERTA(P_FECHA date) is
SELECT P_FECHA V_MES,GSM, CUENTA,DESC_REGION,UPPER(DESC_TIPO_PROD),FECHA_ACTIVACION,DESC_PLAN,0 V_CANGSM,CODIGO_VIP,DESC_CODIGO_VIP,IDENTIFICACION
  FROM SOPFUN.PA_CONTACTOS_DIGITEL
 WHERE ID_EST_SUSC!='DESACTV';


TYPE T_INSERTA IS TABLE OF INSERTA%ROWTYPE INDEX BY PLS_INTEGER;
V_INSERTA T_INSERTA;


BEGIN

EXECUTE IMMEDIATE ('TRUNCATE TABLE TT_DW_FCT_SEGMENTACION_OPT2');
START_TIME := DBMS_UTILITY.GET_TIME;
OPEN INSERTA(TO_DATE('20140710','YYYYMMDD'));
LOOP
FETCH INSERTA BULK COLLECT INTO V_INSERTA LIMIT 100000;
  FORALL I IN 1..V_INSERTA.Count
    INSERT INTO TT_DW_FCT_SEGMENTACION_OPT2 (V_MES,V_SUSC,V_CUENTA,DESC_REGION ,V_TIPO,V_FACTVN,V_PLAN,V_CANGSM,VIP_CODE,DESC_VIP_CODE,CEDULA)
    VALUES V_INSERTA(i);
  EXIT WHEN INSERTA%NOTFOUND;
END LOOP;
CLOSE INSERTA;
END_TIME := DBMS_UTILITY.GET_TIME;
DBMS_OUTPUT.PUT_LINE('BULK INSERT: '||TO_CHAR(END_TIME-START_TIME));

END;

执行时会抛出以下错误：

Line    Pos Text
24  5   ORA-06550: line 24, column 5:
PL/SQL: ORA-00947: not enough values
ORA-06550: line 24, column 5:
PL/SQL: SQL Statement ignored

我不知道为什么会丢失因为它们被声明为值var类型...你能帮助我吗？

Answer 1

替换：

VALUES V_INSERTA(i);

使用：

VALUES (V_INSERTA(i).v_mes, V_INSERTA(i).gsm, ...);

更快更简单的方法是使用单个SQL语句：

INSERT INTO TT_DW_FCT_SEGMENTACION_OPT2 (V_MES,V_SUSC,V_CUENTA,DESC_REGION ,V_TIPO,V_FACTVN,V_PLAN,V_CANGSM,VIP_CODE,DESC_VIP_CODE,CEDULA)
SELECT date '2014-07-10',GSM, CUENTA,DESC_REGION,UPPER(DESC_TIPO_PROD),FECHA_ACTIVACION,DESC_PLAN,0 V_CANGSM,CODIGO_VIP,DESC_CODIGO_VIP,IDENTIFICACION
  FROM SOPFUN.PA_CONTACTOS_DIGITEL
 WHERE ID_EST_SUSC!='DESACTV';

Answer 2

插入字体可以更改为

INSERT INTO TT_DW_FCT_SEGMENTACION_OPT2 
VALUES V_INSERTA(i);

使用forall大容量插入的问题
