Question

我写了一个连接查询语句。该语句再次返回多个（重复）行，即使我只有单个记录。

declare @BenefitClass int ;

set @BenefitClass = (select BenefitClass  From HJOB where userid='d76c5000-69e0-461e-92e1-3cfe7590d098' and CompanyId =1629)
select @BenefitClass;
select   
bve.EmployerContribution,  
bhsac.CatchUpValue as CatchUpValue  ,  
bcl.Tier,  
bcl.planYear,  
bhsac.Ischecked,  
isnull(bhsac.Value,0) as EmployeeContribute,  
Id=(convert(varchar, bcl.Id) + '$' + convert(varchar, isnull(bhsac.Id, 0))) ,  
bhsac.Value ,
bhsac.HSALmitId  
from    
dbo.benContributionStructure bcs   
inner join  dbo.benVariableElection bve on bcs.PlanInfoId = bve.PlanInfoId   
inner join dbo.benBenefitContributionLimit bcl on bcs.SavingCategory =       bcl.CategoryID  
left outer join dbo.benBenefitHSACoverage bhsac on bcs.PlanInfoId =   bhsac.planInfoId 
        and bcl.Id=bhsac.HSALmitId --and bhsac.BenefitClassId=@BenefitClass 
        and bhsac.UserID='d76c5000-69e0-461e-92e1-3cfe7590d098' and  bhsac.PlanInfoId=38044
left outer join dbo.benEmployeeContribution bec on bhsac.UserID = bec.UserId    and bhsac.BenefitClassId = bec.BenefitClassId -- and  bec.EnrollmentType !='Closed'
left outer join benOpenEnrollment oems on oems.ID = bec.OpenEnrollmentId and  oems.EndDt > GETDATE()               
where    
bcs.PlanInfoId=38044  and bcl.Ischecked=1   
                       and bcl.Tier !='CatchUp'    
     and bcl.CompanyId=1629

为此，我将结果作为副本获得第二行：

一旦它可以帮助你，试试这个

declare @BenefitClass int ;

set @BenefitClass = (select BenefitClass  From HJOB where userid='d76c5000-69e0-461e-92e1-3cfe7590d098' and CompanyId =1629)
select @BenefitClass;

;with cte as (
select   
bve.EmployerContribution,  
bhsac.CatchUpValue as CatchUpValue  ,  
bcl.Tier,  
bcl.planYear,  
bhsac.Ischecked,  
isnull(bhsac.Value,0) as EmployeeContribute,  
Id=(convert(varchar, bcl.Id) + '$' + convert(varchar, isnull(bhsac.Id, 0))) ,  
bhsac.Value ,
bhsac.HSALmitId  
from    
dbo.benContributionStructure bcs   
inner join  dbo.benVariableElection bve on bcs.PlanInfoId = bve.PlanInfoId   
inner join dbo.benBenefitContributionLimit bcl on bcs.SavingCategory =       bcl.CategoryID  
left outer join dbo.benBenefitHSACoverage bhsac on bcs.PlanInfoId =   bhsac.planInfoId

     )
     select distinct EmployerContribution,
