如何在SQL中合并两列

这是我的Qyery

 Select FinancialId,
        ApplicationId,
        UPPER (InterestSubsidyFinancialDetail.BankName) as BankName,    
        InterestSubsidyFinancialDetail.BankId,
        BankMaster.BankName as Bank

 From   InterestSubsidyFinancialDetail

 left join BankMaster On BankMaster.BankId = InterestSubsidyFinancialDetail.BankId

此查询给我的结果如下：

FinancialId   ApplicationId     BankName       BankId   Bank
1              1                HARSH BANK        -1    NULL
7              3                                   1    Allahabad Bank
8              3                JFGJFGJ           -1    NULL

但我需要将“BankName”列和“Bank”列合并为：

FinancialId   ApplicationId     BankName       BankId   
1              1                HARSH BANK        -1    
7              3                Allahabad Bank     1                
8              3                JFGJFGJ           -1    

这有可能得到我想要的结果吗？如果是，请帮助我 谢谢

请尝试：

select 
    FinancialId,
    ApplicationId,
    ISNULL(UPPER (InterestSubsidyFinancialDetail.BankName), '')+ISNULL(BankMaster.BankName, '') as BankName,    
    InterestSubsidyFinancialDetail.BankId
From   
    InterestSubsidyFinancialDetail left join 
        BankMaster On BankMaster.BankId = InterestSubsidyFinancialDetail.BankId

请尝试：

select 
    FinancialId,
    ApplicationId,
    ISNULL(UPPER (InterestSubsidyFinancialDetail.BankName), '')+ISNULL(BankMaster.BankName, '') as BankName,    
    InterestSubsidyFinancialDetail.BankId
From   
    InterestSubsidyFinancialDetail left join 
        BankMaster On BankMaster.BankId = InterestSubsidyFinancialDetail.BankId

你可以用这个

Select FinancialId,
        ApplicationId,
        ISNULL(UPPER (InterestSubsidyFinancialDetail.BankName),'') + 
        ISNULL(BankMaster.BankName,'')
        as BankName,    
        InterestSubsidyFinancialDetail.BankId

 From   InterestSubsidyFinancialDetail

 left join BankMaster On BankMaster.BankId = InterestSubsidyFinancialDetail.BankId

你可以用这个

Select FinancialId,
        ApplicationId,
        ISNULL(UPPER (InterestSubsidyFinancialDetail.BankName),'') + 
        ISNULL(BankMaster.BankName,'')
        as BankName,    
        InterestSubsidyFinancialDetail.BankId

 From   InterestSubsidyFinancialDetail

 left join BankMaster On BankMaster.BankId = InterestSubsidyFinancialDetail.BankId

使用

COALESCE

功能，这正是您需要的：

SELECT FinancialId,
       ApplicationId,
       COALESCE(UPPER(InterestSubsidyFinancialDetail.BankName), BankMaster.BankName) as BankName,    
       InterestSubsidyFinancialDetail.BankId
FROM   InterestSubsidyFinancialDetail
LEFT JOIN BankMaster 
     ON BankMaster.BankId = InterestSubsidyFinancialDetail.BankId

哪个版本的sql server支持关键字

CONCAT

？哪个版本的sql server支持关键字

CONCAT

？nitin查询是正确的，但在本例中，UPPER位于ISNULL内，因为Aijaz希望与字段名相同。不是大写。nitin查询是正确的，但在本例中，大写在ISNULL中，因为Aijaz希望与字段名相同。不是大写。
