oracle中逗号分隔的varchar和数字字段存在问题,oracle,plsql,Oracle,Plsql,我在Oracle中编写了以下存储过程： CREATE OR REPLACE PROCEDURE TMS.SP_BOOKING_CANCEL_SMPL(P_BOOK_TERMINAL NUMBER, P_BOOK_CODE NUMBER, P_BOOK_

我正在使用参数'p_CANCELLATION_SEATS'执行此存储过程，参数值为'10,12' 但是它抛出了异常：Ora-01722（无效数字）在第一个查询中，问题很可能是in子句比较了我的参数中的数字类型列值和字符串类型值。

有人能告诉我如何解决这个问题吗？

参数p\u CANCELLATION\u SEAT是一个逗号分隔的值列表，您希望在IN子句中传递这些值。您试图实现的方法在技术上是错误的，在IN子句中使用它之前，必须将逗号分隔的值分解为值列表

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)';

顺便说一句，为什么要使用动态SQL？所有操作都可以使用简单的SQL语句执行。

顺便说一句，为什么要使用动态SQL？所有操作都可以使用简单的SQL语句来执行。

在运行过程之前，您必须记住的几件事。第一个问题是您是否需要

动态SQL

。在您的情况下，根本不需要动态SQL。您可以按照下面我的代码所示直接执行。其次，您已经确定您的表列

BOOKD_SEAT

是一个

数字

coulmn，并且您正在尝试与

字符串

进行比较，因此它显然会出错。您需要将这些值作为集合传递。见下文：

您修改了代码：
