使用UNION ALL将6个查询合并到一个查询中。

UNION ALL

不是一个选项，因为您需要将每个状态的聚合结果分开，并将它们合并到一行中

如果状态量是静态的，则接收所需状态的最简单方法如下：

select
    LoanType,
    sum(MyOutStanding_BL) as MyOutStanding_BL,
    sum(NoofFile_BL) as NoofFile_BL,
    sum(MyOutStanding_DF) as MyOutStanding_DF,
    sum(NoofFile_DF) as NoofFile_DF,
    sum(MyOutStanding_SS) as MyOutStanding_SS,
    sum(NoofFile_SS) as NoofFile_SS,
    sum(MyOutStanding_SMA) as MyOutStanding_SMA,
    sum(NoofFile_SMA) as NoofFile_SMA,
    sum(MyOutStanding_UC) as MyOutStanding_UC,
    sum(NoofFile_UC) as NoofFile_UC,
    sum(MyOutStanding_Regular) as MyOutStanding_Regular,
    sum(NoofFile_Regular) as NoofFile_Regular,
    Reg_MyOutStanding='',Reg_NoofFile='',
    sum(MyOutStanding_SS + MyOutStanding_DF + MyOutStanding_BL) as MyOutStanding_CL,
    sum(NoofFile_SS + NoofFile_DF + NoofFile_BL) as NoofFile_CL
from
(
    SELECT
        LoanType,
        case when Status = 'BL' then SUM(MyOutStanding) else 0 end AS MyOutStanding_BL,
        case when Status = 'BL' then COUNT(NoofFile) else 0 end AS NoofFile_BL,
        case when Status = 'DF' then SUM(MyOutStanding) else 0 end AS MyOutStanding_DF,
        case when Status = 'DF' then COUNT(NoofFile) else 0 end AS NoofFile_DF,
        case when Status = 'SS' then SUM(MyOutStanding) else 0 end AS MyOutStanding_SS,
        case when Status = 'SS' then COUNT(NoofFile) else 0 end AS NoofFile_SS,
        case when Status = 'SMA' then SUM(MyOutStanding) else 0 end AS MyOutStanding_SMA,
        case when Status = 'SMA' then COUNT(NoofFile) else 0 end AS NoofFile_SMA,
        case when Status = 'UC' then SUM(MyOutStanding) else 0 end AS MyOutStanding_UC,
        case when Status = 'UC' then COUNT(NoofFile) else 0 end AS NoofFile_UC,
        case when Status = 'Regular' then SUM(MyOutStanding) else 0 end AS MyOutStanding_Regular,
        case when Status = 'Regular' then COUNT(NoofFile) else 0 end AS NoofFile_Regular
    FROM
        (
            SELECT
                CASE
                    WHEN loantype = 'Auto Loan' THEN 'Auto Loan' 
                    WHEN loantype = 'Home Loan' THEN 'Home Loan'
                    WHEN loantype = 'Home Mortgage Loan' THEN 'Home Mortgage Loan'
                    ELSE 'Any Purpose Loan' END
                AS LoanType, 
                SUM(outstanding) AS MyOutStanding,
                COUNT(clid) AS NoofFile,
                Status
            FROM dbo.RecTestCL
            GROUP BY loantype, Status
        ) X
    GROUP BY LoanType, Status
) rez
group by LoanType

在这种情况下，您还可以执行CL实体的计算（如已添加的—某些其他列的总和）。同样，可以计算附加列（如总计、%等）。在本例中，您只需要一个查询，它返回报表所需的所有计算数据

无法使用Pivot，因为需要在同一查询中计算

总和（MyOutStanding）

和

计数（NoofFile）

享受。

UNION ALL是一个选项，因为可以在Excel中毫无问题地处理数据透视。
