ストアドプロシージャから一時テーブル内のIDを経由して行を更新する必要があります

Question

私は、停止を記述するテーブルで行を取り出し、別のテーブルに挿入して記述するために計算時間範囲で分割しますそれぞれの所与の範囲内の1時間ごとの時間帯。

以下のコード私たちに次のような出力が得られます。

私たちは、この行（元データ）から行ってきました！私はストアドプロシージャ（これは所望の出力ISを実行した後、これに

OutageDate  StartTime     EndTime    Duration 
2010-11-10 16:00:00.0000000 17:30:00.0000000 90 

私はちょうど）テーブルに保存する方法を知っておく必要があります。

OutageDate StartHour StartMinutes EndHour EndMinutes StartTime  EndTime  Duration 
2010-11-10 16 0  17  0  16:00:00.0000000  17:30:00.0000000 90 
2010-11-10 17 30  18  0  16:00:00.0000000  17:30:00.0000000 90 

次私は私がしたい時間値を越え、私の行を分割後のテーブルに保存する方法を把握する必要があるコードです。これが起こることを持っている理由、それはちょうどこの形式でそれらによって私よりも誰かによって要求ごとのようにする必要があると指定した上で、私はコントロールを持っていない：

--First, let's look at the original data in the table...just one row will do 

SELECT TOP (1) * 
    FROM actualTable 
    ORDER BY OutageDate ASC 

--Begin sproc logic

SELECT TOP(1) @OutageDate = OutageDate, @StartTime = StartTime, @EndTime = EndTime, @Duration = Duration FROM actualTable 


SET @Temp_StartTime=@StartTime

PRINT @EndTime 

if(@temp_EndMinute>0) 
    BEGIN 
     SET @temp_EndHour=@temp_EndHour+1 
    END 

--this declares the temp table 

DECLARE @Temp_Table TABLE

--DATEADD returns a specified date with the specified number interval (signed integer) added to a specified datepart of that date.

      END 
    END 

--Ok, if we're at the last row insertion, we still need the minutes the outage finished at...those go into StartMinutes 

    WHile((@temp_EndHour-@temp_StartHour=1)) 
    BEGIN 
     INSERT INTO @Temp_Table 
     SELECT

--Need to add logic that drops and recreates the table from the temp table so we don't have to employ a cursor

YOUがSMSでこのSTRAIGHTを実行する場合、 「は、その最も基本的で論理を得るでしょう：

declare @StartTime time

SELECT * FROM @Temp_Table 

Answer 1

はまず、いくつかのセットアップ：今

USE tempdb; 
GO 

CREATE TABLE dbo.Outages 
(
    OutageDate DATE, 
    StartTime TIME(7), 
    EndTime TIME(7), 
    Duration INT 
); 

INSERT dbo.Outages SELECT '20101110', '16:00', '17:30', 90; 
/* 
-- I also tested these cases, and *think* it still produces what you expect: 
INSERT dbo.Outages SELECT '20101111', '13:00', '14:02', 62; 
INSERT dbo.Outages SELECT '20101112', '17:00', '18:00', 60; 
INSERT dbo.Outages SELECT '20101113', '16:05', '16:25', 20; 
INSERT dbo.Outages SELECT '20101114', '16:59', '18:01', 62; 
INSERT dbo.Outages SELECT '20101115', '22:15', '01:30', 165; 
*/ 

、クエリ：

例えば

;WITH n(n) AS 
(
    SELECT TOP 24 ROW_NUMBER() OVER (ORDER BY [object_id]) 
    FROM sys.objects 
), 
x AS 
(
    SELECT 
    o.OutageDate, StartHour = (DATEPART(HOUR, StartTime) + n.n - 1) % 24, 
    StartTime, EndTime, Duration, 
    rn = ROW_NUMBER() OVER (PARTITION BY o.OutageDate, o.StartTime ORDER BY n.n) 
    FROM n INNER JOIN dbo.Outages AS o 
    ON n.n <= CEILING(DATEDIFF(MINUTE, CONVERT(DATETIME, StartTime), 
    DATEADD(DAY, CASE WHEN EndTime < StartTime THEN 1 ELSE 0 END, 
    CONVERT(DATETIME, EndTime)))/60.0) 
), 
mx AS (SELECT OutageDate, StartTime, minrn = MIN(rn), maxrn = MAX(rn) 
    FROM x GROUP BY OutageDate, StartTime) 

-- insert into some other table 
SELECT 
    x.OutageDate, 
    x.StartHour, 
    StartMinutes = CASE 
     WHEN x.rn = mx.minrn THEN DATEPART(MINUTE, x.StartTime) ELSE 0 END, 
    EndHour = x.StartHour + 1, 
    EndMinutes = CASE 
     WHEN x.rn = mx.maxrn THEN DATEPART(MINUTE, x.EndTime) ELSE 0 END, 
    x.StartTime, 
    x.EndTime, 
    x.Duration 
FROM x INNER JOIN mx 
ON x.OutageDate = mx.OutageDate 
AND x.StartTime = mx.StartTime 
ORDER BY x.OutageDate, x.rn; 
GO 

あなたはそれが実際に挿入して

-- insert into some other table 

を交換、その後、さまざまなシナリオのためにあなたの右の行を与えていることを満足しています、例えば

INSERT dbo.OtherTable(col1, col2, ...) 

あなたはINTO句で

FROM x INNER JOIN mx 

を交換、その後、この出力からブランドの新しいテーブルを作成しようとしている場合は、

INTO dbo.MyNewTable FROM x INNER JOIN mx 

は、クリーンアップすることを忘れないでください：

DROP TABLE dbo.Outages;
