Question

我添加了Project_Contract.ContractorName但查询得到了错误。消息156，级别15，状态1，行18关键字“GROUP”附近的语法不正确。

select top (100) percent dbo.Project_Profile.Project_ID
    ,dbo.Project_Contract.ContractorName
    ,dbo.Schemes.Scheme_Name as [Name of Project]
    ,dbo.Program_Ctrl.Program_Title as [Contract Status]
    ,dbo.District_Ctrl.District_Name as District
    ,M.Module_Title as Module
    ,(
        select MAX(Progress_Percentage) as Expr1
        from dbo.Progress_Reporting as PR
        where (M.ModuleID = Module_Id)
            and (dbo.Milestone_Ctrl.Milestone_ID = Project_Milestone_ID)
            and (Progress_Type = 'A')
        ) as Milestone_Percent_Share
    ,dbo.Milestone_Ctrl.Milestone_Title

        on M.ModuleID = dbo.Project_Milestones.ModuleId 
group by dbo.Project_Profile.Project_ID
        ,dbo.Project_Contract.ContractorName

        ,M.ModuleID
order by dbo.Project_Profile.Project_ID

Answer 1

您有两个加入Project_Profile表并且此加入只有一个ON，您必须添加另一个ON来解决您的问题或删除dbo.Project_Profile INNER JOIN部分命令。

Answer 2

下面：

                         dbo.Project_Profile INNER JOIN
                         dbo.Project_Profile INNER JOIN

没有别名的重复Project_Profile

查询中的MSSQL Group By Error
