BUG：ORA_00913 Oracle 错误 - 值太多

Question

下面的代码在存储过程中，他们告诉我将它转换成嵌套循环并尝试运行ning 它。

    ,decode(a.provider_class, 0, '''', (

    ,a.INACTIVE_DT as INACTIVE_DT

我将上面的代码转换为嵌套循环，请在下面找到转换后的嵌套循环，当我尝试运行下面的这个脚本时，它提示我一个错误：值太多。你能告诉我到底是什么问题吗

  (select a.INACTIVE_DT,a.seqnum,b.seqnum  AS INACTIVE_DT from rate_usage_overrides a, rate_usage_bands_overrides b where a.seqnum = b.seqnum(+))

Answer 1

运行单个查询 c.corridor_plan_id 来自 wards 的第一个查询并检查至少一个查询 returns 超过一个值

Answer 2

这是你的错误

(select a.ACTIVE_DT,a.seqnum,b.seqnum  AS ACTIVE_DT from rate_usage_overrides a, rate_usage_bands_overrides b where a.seqnum = b.seqnum(+)),

  (select a.INACTIVE_DT,a.seqnum,b.seqnum  AS INACTIVE_DT from rate_usage_overrides a, rate_usage_bands_overrides b where a.seqnum = b.seqnum(+))

两个查询都将 return 3 个字段但插入仅指定一列，这就是您收到此错误的原因。顺便说一句，这不是错误
