我知道这不起作用，但这就是我要做的事情

PIVOT（SUM（LAVG），计数（患者）FOR IN月（jan，feb，mar ect

ALTER PROCEDURE [dbo].[Spoclos]
  -- Add the parameters for the stored procedure here
  @Year      INT,
  @PayerCode VARCHAR(3),
  @ID        INT
AS
  BEGIN
      -- SET NOCOUNT ON added to prevent extra result sets from
      -- interfering with SELECT statements.
      SET NOCOUNT ON;

      -- Insert statements for procedure here
      SELECT *
      FROM   (SELECT LEFT(Months, 3) AS Months,
                     FacilityName,
                     LAVG,
                     Patient,
                     Region,
                     ID,
                     payercode,
                     facilityCode
              FROM   dbo.LOSGroup
              WHERE  PayerCode = @PayerCode
                     AND years = @year
                     AND ID = @id) AS s
             PIVOT (Sum(LAVG)
                   FOR months IN (jan,feb,mar,apr,
                        may,jun,jul,aug,
                        sep,oct,nov,dec)) AS piv
      ORDER  BY ID
  END

正如您所提到的，您在枢轴内不能有两个Aggregate函数。

有两个单独的Pivot个查询，一个用于查找Sum，另一个用于查找Count。然后使用Union All结合结果。

SELECT 'Sum' [Aggregate],*
FROM   (SELECT LEFT(Months, 3) AS Months,
               FacilityName,LAVG,Patient,
               Region,ID,payercode,
               facilityCode
        FROM   dbo.LOSGroup
        WHERE  PayerCode = @PayerCode
               AND years = @year
               AND ID = @id) AS s
       PIVOT (Sum(LAVG)
             FOR months IN (jan,feb,mar,apr,
                            may,jun,jul,aug,
                            sep,oct,nov,dec)) AS piv
UNION ALL
SELECT 'Count' [Aggregate],*
FROM   (SELECT LEFT(Months, 3) AS Months,
               FacilityName,LAVG,Patient,
               Region,ID,payercode,
               facilityCode
        FROM   dbo.LOSGroup
        WHERE  PayerCode = @PayerCode
               AND years = @year
               AND ID = @id) AS s
       PIVOT (Count(LAVG)
             FOR months IN (jan,feb,mar,apr,
                            may,jun,jul,aug,
                            sep,oct,nov,dec)) AS piv
ORDER  BY ID

注意：要区分Sum和Count我使用了额外的列Aggregate

转向两个聚合字段
