【问题描述】：

在程序之外似乎可以正常工作，但在程序内部时它似乎没有做任何事情。该过程符合并无错误地运行，但不插入任何行。谁能帮帮我，拜托。

【问题讨论】：

为什么要使用动态 SQL？
别忘了提交。
我正在使用 SQL Developer 进行编码。
是的，但是您在此处发布的代码中没有任何内容证明使用动态 SQL 是合理的。
是的，这就是 INSERT INTO ... SELECT FROM 所做的。这不需要动态 SQL。只需将 SQL 放入过程中即可。我们只需要在有条件地更改 SQL 时使用动态 SQL，例如根据一些输入参数改变目标表

【解决方案1】：

如果执行插入的会话中没有提交问题，则在发出提交之前，其他会话将无法使用记录。如果会话在提交之前退出，那么记录会回滚。

答案：用逗号分隔

结束 CA_RETAIL_TRANSACTION_INSERT；
