从UDF结果

Question

我有一张像这样的表@ROOMS_BY_DEPA_KEY1：

DECLARE @ROOMS_BY_DEPA_KEY1 TABLE
(               
    OPRO_KEY INT,               
    KAPACITETA INT,             
    WEEK_1 DECIMAL(8,2),
    WEEK_2 DECIMAL(8,2),
    WEEK_3 DECIMAL(8,2),
    WEEK_4 DECIMAL(8,2),
    WEEK_5 DECIMAL(8,2),
    WEEK_6 DECIMAL(8,2)
)

INSERT INTO @ROOMS_BY_DEPA_KEY1(OPRO_KEY)
VALUES (160000014),(160000015),(160000016),(160000017),(160000018),(160000019),(160000020)

所以在填写一些数据表之后如下：

我必须使用此表中的结果更新每个行WEEK_1，WEEK_2，WEEK_3，WEEK_4，WEEK_5，WEEK_6，这是从OPRO_KEY和KAPACITETA生成的：

DECLARE @WEEKS_MONTH AS DBO.WEEKS_MONTH_Type
(
    WEEKOFMONTH INT,
    WEEKSTART DATE,
    WEEKEND DATE, 
    NO_DAYS INT, 
    AVERAGE_AVAI DECIMAL(8,2)
)

（它的表格类型，因为它被用作函数参数）。该表的结果如下所示：

要获得第二个表，我有一个UDF：

dbo.f_SCAVAI_GetWeekAverage(@iOPRO_KEY, @WEEKS_MONTH, '1', @iKAPACITETA)

表@WEEKS_MONTH填充了一些值（weekofmonth，datestart，dateend，no_days），每次调用都保持不变：

我的问题是如何为每个OPRO_KEY调用此函数以及如何从返回表更新周列？ 列根据WEEKOFMONTH进行更新。示例：WEEK_1更新@WEEK_MONTHS.WEEK_OF_MONTH = 1，WEEK_2其中@WEEK_MONTHS = 2

Answer 1

如果您总是有6个星期，更新@ ROOMS_BY_DEPA_KEY1表的最简单方法是使用@Weeks_Month表的轴：

UPDATE @ROOMS_BY_DEPA_KEY1
SET Week_1 = w.Week_1
    ,Week_2 = w.Week_2
    ,Week_3 = w.Week_3
    ,Week_4 = w.Week_4
    ,Week_5 = w.Week_5
    ,Week_6 = w.Week_6
FROM 
   (SELECT *
    FROM (SELECT 'Week_' + CAST(WeekOfMonth AS VARCHAR) AS WeekName
            ,Average_Avai
        FROM @WEEKS_MONTH) wm
    PIVOT (MAX(Average_Avai) 
           FOR WeekName IN (Week_1, Week_2, Week_3, Week_4, Week_5, Week_6)
          )p
    ) w

Answer 2

我设法解决了这个问题：

UPDATE RM
                SET RM.WEEK_1 = (
                    SELECT P.AVERAGE_AVAI FROM dbo.f_SCAVAI_GetWeekAverage(RM.DEPA_KEY, RM.OPRO_KEY, @WEEKS_MONTH, @cWorkDaysOnly, RM.KAPACITETA) P WHERE P.WEEKOFMONTH = 1
                ),
                RM.WEEK_2 = (
                    SELECT P.AVERAGE_AVAI FROM dbo.f_SCAVAI_GetWeekAverage(RM.DEPA_KEY,RM.OPRO_KEY, @WEEKS_MONTH, @cWorkDaysOnly, RM.KAPACITETA) P WHERE P.WEEKOFMONTH = 2
                ),
                RM.WEEK_3 = (
                    SELECT P.AVERAGE_AVAI FROM dbo.f_SCAVAI_GetWeekAverage(RM.DEPA_KEY,RM.OPRO_KEY, @WEEKS_MONTH, @cWorkDaysOnly, RM.KAPACITETA) P WHERE P.WEEKOFMONTH = 3
                ),
                RM.WEEK_4 = (
                    SELECT P.AVERAGE_AVAI FROM dbo.f_SCAVAI_GetWeekAverage(RM.DEPA_KEY,RM.OPRO_KEY, @WEEKS_MONTH, @cWorkDaysOnly, RM.KAPACITETA) P WHERE P.WEEKOFMONTH = 4
                ),
                RM.WEEK_5 = (
                    SELECT P.AVERAGE_AVAI FROM dbo.f_SCAVAI_GetWeekAverage(RM.DEPA_KEY,RM.OPRO_KEY, @WEEKS_MONTH, @cWorkDaysOnly, RM.KAPACITETA) P WHERE P.WEEKOFMONTH = 5
                ),
                RM.WEEK_6 = (
                    SELECT P.AVERAGE_AVAI FROM dbo.f_SCAVAI_GetWeekAverage(RM.DEPA_KEY,RM.OPRO_KEY, @WEEKS_MONTH, @cWorkDaysOnly, RM.KAPACITETA) P WHERE P.WEEKOFMONTH = 6
                )
                FROM @ROOMS_BY_DEPA_KEY1 RM
