Sql 如果需要，请使用两列

我使用Case When根据两列计算五列。但它没有给出正确的值。我附上了正确结果的截图。 结果需要如下： 业务逻辑是-这五个计算字段具有不同的定义，并且取决于前置字段。EER的定义是，如果一个ID从某个队列中通过，但也没有通过FBR、CVL和CSP等队列。EER字段在一个ID的所有行中都应该有Yes。对于其余四个计算字段，这与case when语句中的方式相同。计算EER后，应计算其余ID的EES。所以我使用EER，EES需要为null。一个ID在五个字段中的一个字段中为是，对于同一ID，在其余四个字段中为空

CREATE TABLE Table1
    ([ID] int, [QUEUE] varchar(7), [EER] varchar(4), [EES] varchar(4), [EEN] varchar(4), [EBNP] varchar(4), [NSB] varchar(4))
;

INSERT INTO Table1
    ([ID], [QUEUE], [EER], [EES], [EEN], [EBNP], [NSB])

我的尝试是：

Select Distinct X.ID,X.Queue,
case when X.Queue in ('IPTEST','IPPRV','IPPRECF','IPPMOM','IPCON','IPCFG','BDWXNG','LOCCLOS','BDWCNFG','BDWROUT')
and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%' and X.Queue not Like '%CSP%'
then 'Yes'else 'Null' end AS EER,
case when EER = 'Null' and X.Queue not in ('CSPWORK','CSPRACK','CSPEQUP') and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%'
then 'Yes'else 'Null' end AS EES,
case when EER = 'Null' and EES = 'Null' and X.Queue Like '%CSP%' and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%'
then 'Yes'else 'Null' end AS EEN,
case when EER = 'Null' and EES = 'Null' and EEN= 'Null'and X.Queue not Like '%CVL%'
then 'Yes'else 'Null' end AS EBNP,
case when EER = 'Null' and EES = 'Null' and EEN= 'Null' and EBNP = 'Null' and X.Queue Like '%CVL%'
then 'Yes'else 'Null' end AS NSB

正如@HoneyBadger所提到的，您应该做的是空检查，而不是相等运算符。注意：没有两个空值是相等的，因为空值只是表示缺少值的标记

因此，查询应该是

Select Distinct X.ID,X.Queue,
case when X.Queue in ('IPTEST','IPPRV','IPPRECF','IPPMOM','IPCON','IPCFG','BDWXNG','LOCCLOS','BDWCNFG','BDWROUT')
and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%' and X.Queue not Like '%CSP%'
then 'Yes'else Null end AS EER,
case when EER is Null and X.Queue not in ('CSPWORK','CSPRACK','CSPEQUP') and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%'
then 'Yes'else Null end AS EES,
case when EER is Null and EES is Null and X.Queue Like '%CSP%' and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%'
then 'Yes'else Null end AS EEN,
case when EER is Null and EES is Null and EEN is Null and X.Queue not Like '%CVL%'
then 'Yes'else Null end AS EBNP,
case when EER is Null and EES is Null and EEN is Null and EBNP is Null and X.Queue Like '%CVL%'
then 'Yes'else Null end AS NSB

以上是您的预期结果吗？您似乎忘记包含示例数据，因此我们不知道如何获得该结果。你能提供样品和预期结果吗？首先只计算一列并评估结果，就一列提问。那么我也将为大家简单介绍一下什么输出是不正确的？您给出的值是输入，您给出的SQL与您在输入中给出的EER值不同-这是问题所在吗？第一行中的“LOCCLOS”在您的“in”条件列表中，但它与您要求的任何异常都不一样-因此与“%FBR%”不一样的情况将是真实的-例如-整个事情的评估结果似乎都是真实的-即。它归结为“真与真，真与真”，当您比较

EER='Null'

时，它将变为“真”，但您没有值为

'Null'

的字符串文字，您有一个

NULL

值。检查如下：

EER为空

。谢谢@Juozas，这已向正方向更正。事实上，我正在寻找一个是再次一个ID在需要的结果上面给出。您的代码对一个ID给出了多个“是”。此解决方案-ID队列EER EEN EBNP NSB 180614 BDWCNFG Yes Yes Null Yes Null Null 180614 BDWROUT Yes Null Yes Null Yes Null `我无法理解您的任务。请用简单的语言描述您试图实现的目标：业务逻辑而不是查询。对于要计算的每个列。从您提供的查询中无法理解业务逻辑，因为查询逻辑和期望的结果具有误导性。如果理解不好，我很抱歉。我已经更新了定义并附上了屏幕截图。您的“右”结果屏幕截图中[EER]列有错误。[ID]24048916。[ID]24048916具有[QUEUE]LOCCLO，不包含任何FBR、CVL、CSP。因此，ID 24048916的[ERR]列需要为“Yes”。但你有空。这令人困惑。您的任务很复杂，因此，如果您需要帮助，强烈建议您避免在描述中出现任何错误。@LearnerBee我用新的逻辑更新了我的答案。请使用提供的新查询。请记住，很可能你的结果截图有错误。我真的很感谢你的努力。但这并没有给出正确的结果。我附上了一个正确结果的截图。你的“ansi_NULL”设置为on吗？
