Question

我在Oracle中编写了这个存储过程：

sed -i -E 's/--cgroup-driver=systemd/--cgroup-driver=cgroupfs/' /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

我正在使用参数'P_CANCELLATION_SEATS'执行此存储过程，其值为：'10,12' 但它会抛出异常：第一个查询中的Ora-01722（无效数字），问题很可能是IN子句将Number类型列值与我参数中的字符串类型值进行比较。任何人都可以告诉我如何解决这个问题？

在运行Proc之前，您必须记住几件事。首先是你是否需要DYNAMIC SQL。在您的情况下，根本不需要动态SQL。您可以直接执行此操作，如下面的代码所示。其次，您已经确定表格列BOOKD_SEAT是NUMBER个库，并且您正在尝试与String进行比较，因此很明显它会出错。您需要将这些值作为集合传递。见下文：

您修改了代码：

--Create a type of Number to hold your input values
CREATE OR REPLACE TYPE var IS TABLE OF NUMBER;
/

CREATE OR REPLACE PROCEDURE TMS.SP_BOOKING_CANCEL_SMPL (
   P_BOOK_TERMINAL         NUMBER,
   P_BOOK_CODE             NUMBER,
   P_BOOK_NO               VARCHAR2,
   P_CANCELLATION_SEATS    var, -- Declare the input as  type of NUMBER
   P_CANCEL_QTY            NUMBER,
   P_CANCEL_AMOUNT         NUMBER,
   P_CANCEL_SEAT_QTY       NUMBER,
   P_SEAT_QTY              NUMBER,
   P_UNCANCELLED_ID        VARCHAR2,
   P_UNCANCELLED_QTY       NUMBER,
   P_CANCEL_TERMINAL       NUMBER,
   P_CANCEL_SITE           NUMBER,
   P_CANCEL_SEQ            NUMBER,
   P_CANCEL_TYPE           CHAR,
   P_USER_ID               VARCHAR2,
   P_SYNC                  CHAR,
   P_CREATE_IP             VARCHAR2,
   P_CREATE_PC             VARCHAR2)
IS  
   V_CANCEL_CODE   NUMBER;
BEGIN
   UPDATE TMS_BOOKD
      SET BOOKD_CANCEL_YN = 'Y',
          BOOKD_CANCEL_DATE = SYSDATE,
          BOOKD_CANCEL_USER = P_USER_ID,
          BOOKD_GENDER = NULL
    WHERE     BOOKD_TERMINAL = P_BOOK_TERMINAL
          AND BOOKD_CODE = P_BOOK_CODE
          AND BOOKD_SEAT IN (select column_value from table(P_CANCELLATION_SEATS) );
       -- Note you can also use MEMBER of operator and change query as 
       --BOOKD_SEAT MEMBER OF P_CANCELLATION_SEATS

   IF P_CANCEL_SEAT_QTY = P_SEAT_QTY
   THEN
      UPDATE TMS_BOOKM
         SET BOOKM_SET_SEATS = NULL,
             BOOKM_SET_QTY = NULL,
             BOOKM_SET_AMOUNT = NULL,
             BOOKM_CANCEL = 1
       WHERE     BOOKM_TERMINAL = P_BOOK_TERMINAL
             AND BOOKM_CODE = P_BOOK_CODE
             AND BOOKM_BOOKNO = P_BOOK_NO;
   ELSE
      UPDATE TMS_BOOKM
         SET BOOKM_SET_SEATS = P_UNCANCELLED_ID,
             BOOKM_SET_QTY = P_UNCANCELLED_QTY,
             BOOKM_CANCEL = 1
       WHERE     BOOKM_TERMINAL = P_BOOK_TERMINAL
             AND BOOKM_CODE = P_BOOK_CODE
             AND BOOKM_BOOKNO = P_BOOK_NO;
   END IF;
END;

执行：

DECLARE
   v_var   var := var ();
BEGIN
   v_var.EXTEND (2);

   --Populate all the values which you want to evalued in IN calsue.
   v_var (1) := 1;
   v_var (2) := 2;

   TMS.SP_BOOKING_CANCEL_SMPL (P_BOOK_TERMINAL => <give your value>
                                P_BOOK_CODE   =>  <give your value>
                                P_BOOK_NO     => <give your value>
                                --- pass all the value which you want to be evaluted in IN clause of your query
                                P_CANCELLATION_SEATS  => v_var
                                P_CANCEL_QTY     =>  <give your value>
                               P_CANCEL_AMOUNT    =>  <give your value>
                                P_CANCEL_SEAT_QTY    =>  <give your value>
                                P_SEAT_QTY          =>  <give your value>
                                P_UNCANCELLED_ID     =>  <give your value>
                                P_UNCANCELLED_QTY    => <give your value>
                                P_CANCEL_TERMINAL    => <give your value>
                                P_CANCEL_SITE      =>  <give your value>
                                P_CANCEL_SEQ      =>  <give your value>
                                P_CANCEL_TYPE     =>  <give your value>
                                P_USER_ID     =>  <give your value>
                                P_SYNC        =>  <give your value>
                                P_CREATE_IP    =>  <give your value>
                                P_CREATE_PC     => <give your value>      )

end;

参数P_CANCELLATION_SEAT是您想要在IN子句中传递的逗号分隔值的列表，您尝试实现的方式在技术上是错误的，您必须在将逗号分隔后使用它时将其分隔为值列表IN条款。

d_sql := 'UPDATE TMS_BOOKD SET BOOKD_CANCEL_YN = ''Y'', BOOKD_CANCEL_DATE = SYSDATE, BOOKD_CANCEL_USER = :UserId, BOOKD_GENDER = NULL
                  WHERE BOOKD_TERMINAL = :BookDTerminal AND BOOKD_CODE = :BookDCode AND BOOKD_SEAT in (SELECT to_number(regexp_substr(vlist, ''[^,]+'', 1, LEVEL))
                                                                                                         FROM (SELECT :cancellationIds AS vlist FROM dual)
                                                                                                       CONNECT BY regexp_substr(vlist, ''[^,]+'', 1, LEVEL) IS NOT NULL)';

BTW，你为什么要使用动态SQL？您可以使用简单的SQL语句执行所有操作。
