无法使用 BULK COLLECT 和 FORALL 编译 PL/SQL

我在创建此过程时遇到以下错误。

CREATE OR replace PROCEDURE Remove_sv_duplicate
IS
  TYPE sv_bulk_collect
    IS TABLE OF tt%ROWTYPE;
  sv_rec SV_BULK_COLLECT;
  CURSOR cur_data IS
    SELECT *
    FROM   tt
    WHERE  ROWID IN (SELECT ROWID
                     FROM   (SELECT ROWID,
                                    Row_number () over (PARTITION BY portingtn,
                                    nnsp
                                    , onsp,
                                    spid,
                                    Trunc(
                                            createddate,
                                    'MI') ORDER BY portingtn) dup
                             FROM   tt)
                     WHERE  dup > 1);
BEGIN
  OPEN cur_data;

  LOOP
      FETCH cur_data BULK COLLECT INTO sv_rec LIMIT 1000;

      FORALL i IN 1..sv_rec.COUNT
        INSERT INTO soa_temp_sv_refkey_fordelete
                    (referencekey,
                     spid,
                     nnsp,
                     onsp,
                     portingtn)
        (SELECT referencekey,
                spid,
                nnsp,
                onsp,
                portingtn
         FROM   tt
         WHERE  portingtn = Sv_rec(i).portingtn
                AND spid = Sv_rec(i).spid
                AND nnsp = Sv_rec(i).nnsp
                AND onsp = Sv_rec(i).onsp
                AND svid IS NULL);

      EXIT WHEN cur_data%notfound;
  END LOOP;

  CLOSE cur_data;

  COMMIT;
END; 

程序

您在使用时不能*引用单个字段FORALL- 这就是您收到 PLS-00436 错误的原因。

为了解决这个问题，您必须使用关联数组来引用各个 字段。

DECLARE

    TYPE tt_rectype IS RECORD (
      referencekey tt.referencekey%TYPE,
      spid tt.spid%TYPE,
      nnsp tt.hiredate%TYPE,

      portingtn tt.portingtn%TYPE);

    TYPE tt_aa_type
      IS TABLE OF TT_RECTYPE INDEX BY PLS_INTEGER;

    tt_aa TT_AA_TYPE;
    CURSOR cur_data IS
      SELECT *
      FROM   tt
      WHERE  ROWID IN (SELECT ROWID
                       FROM   (SELECT ROWID,
                                      Row_number () over (PARTITION BY portingtn
                                      ,
                                      nnsp

                                      , 'MI') ORDER BY portingtn) dup
                               FROM   tt)
                       WHERE  dup > 1);
BEGIN
    OPEN cur_data;

    LOOP
        FETCH cur_data BULK COLLECT INTO tt_aa LIMIT 1000;

        FORALL i IN 1..tt_aa.COUNT
          INSERT INTO soa_temp_sv_refkey_fordelete
                      (referencekey,
                       spid,
                       nnsp,
                       onsp,
                       portingtn)
          (SELECT referencekey,
                  spid,
                  nnsp,
                  onsp,
                  portingtn
           FROM   tt

        EXIT WHEN cur_data%notfound;
    END LOOP;

    CLOSE cur_data;

    COMMIT;
END; 

*请注意，Oracle 11g+ 中不再存在此限制

另外，如@乔纳尔斯 https://stackoverflow.com/users/409172/jonearles comments https://stackoverflow.com/questions/8169429/not-able-to-compile-pl-sql-with-bulk-collect-and-forall#comment-10044945，你可以只使用一条 SQL 语句......

             nnsp,
             onsp,
             portingtn)
SELECT referencekey,
       spid,
       nnsp,
       onsp,
       portingtn
FROM   tt
WHERE  ROWID IN (SELECT ROWID
                 FROM   (SELECT ROWID,
                                Row_number () over (PARTITION BY portingtn, nnsp
