Question

我正在尝试运行此查询，但不知何故标签B的底部部分无法运行。

我是甲骨文的新手，我只是看不出有什么不对。谁能帮帮我吗？非常感谢。

当销售人员没有依赖它时，它不会返回任何数据。无论如何，这仍应返回有关基本客户的信息。

Answer 1

您可能希望在查询结尾添加：

WHERE X.REP_ID = B.REP_ID

（并删除第一个DISTINCT）或JOIN的其他条件，否则此查询将返回X中B中记录的所有记录组合

因为你正在寻找

AND   C.CUST_ID     =v_Cust_ID

你应该在加入中使用它！

由于您不确定X中是否存在这些信息，因此您应该在LEFT JOIN上使用X，您可以在Oracle中执行以下操作：

WHERE B.CUST_ID = X.CUST_ID(+)

Oracle Query看不出有什么问题
