Question

有人可以帮助我使用以下代码。即使使用＆lt;＆gt;也会返回结果我以为会把事情排除在外。我根本不熟悉sql并且会感谢任何和所有的帮助。提前谢谢。

    SELECT k109.keyvaluechar as [Transaction Number], k3257.keyvaluechar as [Fund Name], k4666.keyvaluechar as [Fund ID], k4667.keyvaluechar as [Investor Legal Name], k4638.keyvaluechar as [Transaction Type], k4740.keyvaluecurr as [Cash Transaction Amount], k4701.keyvaluedate as [Effective Date], lc.lifecyclename as [Life Cycle], lcs.statename as [Queue], k4795.keyvaluechar as [Missing Document]

Answer 1

(lcs.statename <> 'Client Transactions - Distribution' OR
        lcs.statename <> 'Client Transactions - Initiate' OR
        lcs.statename <> 'Client Transactions - Notifications' OR
        lcs.statename <> 'Client Transactions - FTP Process' OR
        lcs.statename <> 'Client Transactions - Import FTP Docs')

在上面部分用AND

替换所有OR

Answer 2

如果你在谈论这个代码块

id.institution = 13 AND
        (lcs.statename <> 'Client Transactions - Distribution' OR
        lcs.statename <> 'Client Transactions - Initiate' OR
        lcs.statename <> 'Client Transactions - Notifications' OR
        lcs.statename <> 'Client Transactions - FTP Process' OR
        lcs.statename <> 'Client Transactions - Import FTP Docs')

这是因为你在一个或陈述中使用的不是等号。这意味着无论lcs.statename是什么，括号段返回的布尔值将始终为true，因为即使语句是“客户端事务 - 分发”也是如此。它不是＆＃39;客户交易 - 启动＆＃39;这样或链条将得到满足并返回真实。基本上你的陈述看起来像id.institution = 13 AND true。

如果它没有列出任何字符串，你希望它返回false，或者如果它不是其中之一，你希望它返回true

无论哪种方式，您都应该切换所有＆lt;＆gt;到=。这将检查语句是否与这些字符串中的任何一个匹配。如果确实找到匹配，则返回true。如果你想让它返回false，那么在括号前添加一个不反转它。

id.institution = 13 AND NOT
        (lcs.statename <> 'Client Transactions - Distribution' AND
        lcs.statename <> 'Client Transactions - Initiate' AND
        lcs.statename <> 'Client Transactions - Notifications' AND
        lcs.statename <> 'Client Transactions - FTP Process' AND
        lcs.statename <> 'Client Transactions - Import FTP Docs')

SQL select语句返回错误数据（where子句使用＆lt;＆gt;）
