Question

需要有关添加camel和汇总列的帮助。这是我到目前为止的代码：

SELECT  
  CASE WHEN (GROUPING (State) = 1) THEN 'State Total:'
       ELSE ISNULL(State, 'UNKNOWN')
       END AS StateName,
  CASE WHEN (GROUPING(County) = 1) THEN 'County Total:'
       ELSE ISNULL(County, 'UNKNOWN')
       END AS CountyName,
  SUM(WellCount) AS WellCount
FROM tbl
GROUP BY State, County WITH ROLLUP

具有代码：

/*Pulling data and display with appropriate format and show summarized data

You have a simple table of data.

No additional table variables or temp tables should be used

Your task in your sql output:  

    1.  Capitalize the state names
    2.  Convert the county names to camel (meaning first letter is capitalized)
    3.  Show the city data along with county and state totals
    4.  Sort by state, county, city, then totals
*/
SET NOCOUNT ON;

--**--**--
DECLARE @tbl TABLE (State varchar(2), County varchar(40), City varchar(40), WellCount int)

INSERT @tbl VALUES ('ok','la flore','Mcalister',5)
INSERT @tbl VALUES ('ok','la flore','Savannah',2)
INSERT @tbl VALUES ('ok','hughes','Dustin',9)
INSERT @tbl VALUES ('tx','tarrant','Fort Worth',51)
INSERT @tbl VALUES ('tx','tarrant','Burleson',6)
INSERT @tbl VALUES ('tx','parKer','Weatherford',7)
INSERT @tbl VALUES ('ar','bryaNnt','Little Rock',12)
INSERT @tbl VALUES ('ar','bryaNnt','Ozark',12)
INSERT @tbl VALUES ('ar','reeD','Van Buren',46)
INSERT @tbl VALUES ('nm','saN Jaun','Farmington',3)
INSERT @tbl VALUES ('nm','saN Jaun','Bloomfield',3)
INSERT @tbl VALUES ('nm','rio arriba','Durango',104)
--**--**--

示例输出应如下所示：

StateName CountyName     CityName        WellCount
AR        Bryannt        Little Rock     12
AR        Bryannt        Ozark           12
AR        Bryannt        County Total:   24
AR        Reed           Van Buren       46
AR        Reed           County Total:   46
AR        State Total:                   70
NM        Rio Amiba      Durango         104
NM        Rio Amiba      County Total:   104
NM        San Juan       Bloomfield      3
NM        San Juan       Famington       3
NM        San Juan       County Total:   6

Answer 1

如果它适用于其他样本数据，则可以进一步优化。

试试这个，

DECLARE @tbl TABLE (State varchar(2), County varchar(40), City varchar(40), WellCount int)

INSERT @tbl VALUES ('ok','la flore','Mcalister',5)
INSERT @tbl VALUES ('ok','la flore','Savannah',2)
INSERT @tbl VALUES ('ok','hughes','Dustin',9)
INSERT @tbl VALUES ('tx','tarrant','Fort Worth',51)
INSERT @tbl VALUES ('tx','tarrant','Burleson',6)
INSERT @tbl VALUES ('tx','parKer','Weatherford',7)
INSERT @tbl VALUES ('ar','bryaNnt','Little Rock',12)
INSERT @tbl VALUES ('ar','bryaNnt','Ozark',12)
INSERT @tbl VALUES ('ar','reeD','Van Buren',46)
INSERT @tbl VALUES ('nm','saN Jaun','Farmington',3)
INSERT @tbl VALUES ('nm','saN Jaun','Bloomfield',3)
INSERT @tbl VALUES ('nm','rio arriba','Durango',104)

;WITH CTE AS
(
    select *,   DENSE_RANK()over( order by state)rn 
    ,ROW_NUMBER()over(partition by state order by wellcount)rn1 
    ,DENSE_RANK()over(partition by state order by wellcount)rn2
    from @tbl
)
,CTE2 AS
(
    SELECT State ,County ,City ,WellCount,RN,RN1,rn2,0 rn3  FROM CTE 

  UNION ALL

      select a.State ,a.County ,'County Total' ,
      case when a.rn2=b.rn2 then a.WellCount+b.wellcount 
      else case when a.rn1-b.rn1=1 then a.WellCount end end ,a.RN,a.RN1,a.rn2 ,1 rn3
      from cte a inner join cte b on a.rn=b.rn  and (a.rn1-b.rn1=1 )

 UNION ALL

      select a.State ,'State Total' ,'' , a.WellCount+b.wellcount +a.wellcount
        ,a.RN,a.RN1,a.rn2 ,2 rn3
      from cte a inner join cte b on a.rn=b.rn  and (b.rn1-a.rn1=1 ) and b.rn2-a.rn2=1


)
SELECT   * FROM CTE2
ORDER BY rn,wellcount,rn3

Answer 2

我使用这个功能：

    CREATE FUNCTION [dbo].[fs_PascalCase]
    (
        @Text nVarChar(MAX)

    )
    RETURNS nVarChar(MAX)
    AS
    BEGIN
            SET @Text = LOWER(@Text)

            DECLARE @New NVARCHAR(MAX) = (CASE WHEN @Text IS NULL THEN NULL ELSE '' END)

            DECLARE @Len INT = LEN(REPLACE(@Text, ' ', '_'))

            DECLARE @Index INT = 1

            WHILE (@Index <= @Len)
                IF (SUBSTRING(@Text, @Index, 1) LIKE '[^a-z]' AND @Index + 1 <= @Len)
                    SELECT @New = @New + UPPER(SUBSTRING(@Text, @Index, 2)), @Index = @Index + 2
                ELSE
                    SELECT @New = @New + SUBSTRING(@Text, @Index, 1) , @Index = @Index + 1

            RETURN ( UPPER(LEFT(@New, 1)) + RIGHT(@New, ABS(@Len - 1)) )

    END

    GO
