这是一个非常复杂的问题，我提前道歉。我一直在对我的问题进行大量的分析和研究，但我找不到任何答案。
如果这是相关的，我正在使用SQL Server 2008 R2。
我创建了一个根据我的业务规则工作的标量值函数，但在存储过程中使用时需要17分钟才能运行。这也是全部R.B.A.R.这让我很烦恼。
结果，我正在尝试编写一个视图来替换它。我编写并加入存储过程的视图需要7秒才能运行。问题在于它不遵守所有业务规则。
我会发布原始函数和新视图，但首先我会尝试先解释业务规则，因为这一切都很混乱。
如果销售完成，请返回“已完成”。
如果销售编号未完成，但另一位销售人员确实完成了销售，请返回“已保存”。
如果没有销售人员能够完成销售：
一个。并且客户取消了销售，返回“已取消”
湾只有一个销售人员试图进行销售，返回“错过”
℃。不止一个销售人员试图进行销售，但都错过了：
我。如果其中一个销售人员“拥有”客户帐户，请将其电话号码“遗漏”，并将任何其他相关的电话号码“遗漏”
II。如果没有销售人员拥有客户帐户，请将“错过”添加到首先收到订单的销售人员。
最后注意：每个客户订单/销售都有一个统一的“CallNumber”，其中包含一个或多个“SalesNumbers”的列表，这些列表都是销售人员尝试完成订单。

答案 0 :(得分：0)
我终于明白了。
我没有考虑问题的所有可能的排列，因此，视图并没有按照应有的方式处理业务规则。
我最后添加了另一个CTE（虽然，我并不完全确定这些计算为CTE）以及最后的Case语句的进一步逻辑。
