我需要创建一个子句来限制返回的数据。
如果来自PO_headers_all的AUTHORIZATION_STATUS返回STATUS'已批准'和'正在处理'，则不返回供应商。然而，它自己返回“已批准”我需要退回供应商。
这样做的目的是让那些没有优秀PO的供应商退回。
有没有办法做到这一点？

示例输出如下;
172|UMANIS.201|UMANIS|COMPUTER|12988|EXPENSE|24-NOV-11|APPROVED
172|UMANIS.201|UMANIS|COMPUTER|12988|EXPENSE|24-NOV-11|IN PROCESS
如果结果如上所述，我想排除供应商。
答案 0 :(得分：0)
好的，让我们潜入。
但首先是指向How to create a Minimal, Complete, and Verifiable example
的必要指针您可以在此答案中找到（并希望，更正，完整并添加到您的问题中）此类示例的尝试（也在rextester上）。这个例子可以大大简化，因为许多领域并不真正与你的核心问题有关（＆＃34;我如何过滤记录，其中条件是另一个表中存在两个相关记录？＆＃34; ）但是根据您的具体业务要求。
我决定不简化任何事情，因为我希望能够完全测试您提出的问题。
我尝试从查询和示例输出中重新创建您所说的示例数据。
我创建了2个供应商：UMANIS（其标题状态包含＆＃34; APPROVED＆＃34;＆＃34; IN PROCESS＆＃34;因此应该被过滤掉）和ROBOZ（其中标题状态仅包含＆＃34; APPROVED＆＃34;因此应该返回）。

第一个查询返回

172 UMANIS.201 UMANIS SEGM1 EXPENSE 27.04.2015 00:00:00 ACTIVE

第二个只返回ROBOZ

172 ROBOZ.301 ROBOZ SEGM1 EXPENSE 11.03.2015 00:00:00 ACTIVE
至于对第二个查询（我提出的解决方案）的逻辑的解释，我现在很累（00:37 AM），我刚刚加入了pha_headers两次，一次是为了＃34;批准了＆＃ 34;记录和一次用于＆＃34; IN PROCESS＆＃34;记录，所以我可以将它们用作简单的连接，所有记录都在同一记录中。
其他解决方案是可能的，无需访问该表两次（＆＃34;旋转＆＃34;具有聚合函数的表和例如CASE）
