Question

我不想按＆＃34; BimeName.IssueDate ＆＃34;进行分组。这个选择中的字段，我不知道该怎么做。如果我没有在GroupBy子句中指定此字段，我将收到错误。

Msg 8120，Level 16，State 1，Line 2 Column＆＃39; BimeName.IssueDate＆＃39;是在选择列表中无效，因为它不包含在任何一个中聚合函数或GROUP BY子句。

请帮助我！

SELECT
        BimeName.IssueDate,
        sum(BimeName.Premium) as Permium,
        TypeOfInsurances.TypeOfInsurance + ' ' +
        InsuranceKinds.KindOfInsurance as KindOfInsurance,
        InsuranceAgents.NameOfInsurance,
        InsuranceAgents.Representation + ' ' +
        InsuranceAgents.AgentCode as Agent
from    
        BimeName
        Inner Join InsuranceKinds ON InsuranceKinds.Id = BimeName.KindOfInsuranceId
        Inner Join TypeOfInsurances ON TypeOfInsurances.Id = InsuranceKinds.TypeOfInsuranceId
        Inner Join InsuranceAgents ON InsuranceAgents.Id = TypeOfInsurances.InsuranceAgentId
where   
        BimeName.IssueDate BETWEEN '2010-01-01' AND '2017-01-30'
group by InsuranceAgents.Representation, InsuranceAgents.NameOfInsurance, InsuranceAgents.AgentCode  , BimeName.IssueDate  , TypeOfInsurances.TypeOfInsurance , InsuranceKinds.KindOfInsurance

Answer 1

如果您像上面说的那样，不需要它，只需从选择中省略日期字段。

SELECT
        sum(BimeName.Premium) as Permium,
        TypeOfInsurances.TypeOfInsurance + ' ' +
        InsuranceKinds.KindOfInsurance as KindOfInsurance,
        InsuranceAgents.NameOfInsurance,
        InsuranceAgents.Representation + ' ' +
        InsuranceAgents.AgentCode as Agent
from    
        BimeName
        Inner Join InsuranceKinds ON InsuranceKinds.Id = BimeName.KindOfInsuranceId
        Inner Join TypeOfInsurances ON TypeOfInsurances.Id = InsuranceKinds.TypeOfInsuranceId
        Inner Join InsuranceAgents ON InsuranceAgents.Id = TypeOfInsurances.InsuranceAgentId
where   
        BimeName.IssueDate BETWEEN '2010-01-01' AND '2017-01-30'
group by 
        InsuranceAgents.Representation, 
        InsuranceAgents.NameOfInsurance, 
        InsuranceAgents.AgentCode, 
        TypeOfInsurances.TypeOfInsurance, 
        InsuranceKinds.KindOfInsurance

您可以在where子句中包含不在分组中的字段。

Answer 2

没有任何意义。想象一下，它在同一组中的字段 BimeName.IssueDate 具有不同的值，那么必须为该类别选择哪个值？应该再考虑一下。
