我一直在努力做的一組報道，讓熱量以15個分鐘爲增量燒燬的總和爲「團隊」和「用戶。TSQL分組的時間開始和結束日期
我使用的表如下：
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id('Teams') AND OBJECTPROPERTY(id, 'IsTable') = 1)
DROP TABLE Teams;
CREATE TABLE Teams
(
Team_ID int NOT NULL PRIMARY KEY IDENTITY (1,1),
Team_Name varchar(100),
Team_Description varchar(200)
);
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id('Users') AND OBJECTPROPERTY(id, 'IsTable') = 1)
DROP TABLE Users;
CREATE TABLE Users
(
User_ID int NOT NULL PRIMARY KEY IDENTITY (1,1),
User_Name varchar(100)
);
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id('Team_User') AND OBJECTPROPERTY(id, 'IsTable') = 1)
DROP TABLE Team_User;
CREATE TABLE Team_User
(
Team_ID int,
User_ID int
);
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id('Workouts') AND OBJECTPROPERTY(id, 'IsTable') = 1)
DROP TABLE Workouts;
CREATE TABLE Workouts
(
Workout_ID int NOT NULL PRIMARY KEY IDENTITY (1,1),
User_ID int,
Workout_Type int,
Start_Time datetime,
End_Time datetime,
Calories float
);
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id('LK_Workout_Type') AND OBJECTPROPERTY(id, 'IsTable') = 1)
DROP TABLE LK_Workout_Type;
CREATE TABLE LK_Workout_Type
(
WT_ID int NOT NULL PRIMARY KEY IDENTITY (1,1),
Workout_Name varchar (80),
Workout_Description varchar(200)
);
INSERT INTO Teams (Team_Name, Team_Description) VALUES ('A Team', 'We are not vets.');
INSERT INTO Teams (Team_Name, Team_Description) VALUES ('Team Solo', 'One man. One team.');
INSERT INTO Users (User_Name) VALUES ('Frank Appleton');
INSERT INTO Users (User_Name) VALUES ('Tim Murdock');
INSERT INTO Users (User_Name) VALUES ('Tim Smith');
INSERT INTO Team_User (Team_ID, User_ID) Values (1,1);
INSERT INTO Team_User (Team_ID, User_ID) Values (1,2);
INSERT INTO Team_User (Team_ID, User_ID) Values (2,3);
INSERT INTO LK_Workout_Type (Workout_Name, Workout_Description) VALUES ('Bike - Mountain','Trail riding.');
INSERT INTO LK_Workout_Type (Workout_Name, Workout_Description) VALUES ('Bike - Road','Road riding.');
INSERT INTO LK_Workout_Type (Workout_Name, Workout_Description) VALUES ('Elliptical','Standard elliptical');
INSERT INTO LK_Workout_Type (Workout_Name, Workout_Description) VALUES ('Running','Typical running');
INSERT INTO LK_Workout_Type (Workout_Name, Workout_Description) VALUES ('Treadmill','Treadmill running');
INSERT INTO LK_Workout_Type (Workout_Name, Workout_Description) VALUES ('Weights','Weightroom');
INSERT INTO Workouts (User_ID, Workout_Type, Start_Time, End_Time, Calories) VALUES (1,1,'3/10/2012 08:00:00 AM','3/10/2012 09:30:00 AM', 860);
INSERT INTO Workouts (User_ID, Workout_Type, Start_Time, End_Time, Calories) VALUES (2,1,'3/10/2012 08:30:00 AM','3/10/2012 10:45:00 AM', 950);
INSERT INTO Workouts (User_ID, Workout_Type, Start_Time, End_Time, Calories) VALUES (3,5,'3/10/2012 10:05:00 AM','3/10/2012 12:27:00 PM', 1917);
INSERT INTO Workouts (User_ID, Workout_Type, Start_Time, End_Time, Calories) VALUES (1,5,'3/10/2012 02:38:00 PM','3/10/2012 03:17:00 PM', 536);
有一個問題我想生成顯示由給定團隊燃燒的卡路里的報告，在特定的增量和時限所以，如果我想要顯示從8燒燬A-隊的卡路里。上午到下午6點在給定的一天，以15分鐘爲增量，報告應該是這樣的：
TheDt Team Calories
上午八時00分零零秒A-隊860
上午08點15分○○秒A-隊860
上午08時30分00秒A-1810隊
上午8時45分○○秒A-1810隊
上午9時00分〇〇秒A-1810隊
上午9點15分00秒A-1810隊
上午9點30分○○秒A-1810隊
上午09時45分○○秒A-950隊
10： 00:00 AM A-950隊
上午10點一十五分00秒A-950隊
上午十時三十分00秒A-950隊
10:45：上午12點A-950隊
上午11時00分00秒A-隊0
....
下午2點30分〇〇秒A-隊0
下午2點45分00秒A-隊536
下午3點00分〇〇秒特攻隊536
下午3點15分零零秒攻隊536
下午3時30分○○秒A-隊0
...
下午6時00分00秒特攻隊0
在我的研究中，我發現使用表格來支持增量（15分鐘）並將其加入到我的鍛鍊表格中應該會有所幫助。所以，我創建瞭如下表：
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id('Tally') AND OBJECTPROPERTY(id, 'IsTable') = 1)
DROP TABLE Tally;
CREATE TABLE Tally
(N INT,
CONSTRAINT PK_Tally_N PRIMARY KEY CLUSTERED (N))
-----------Create and preset a loop counter
DECLARE @Counter INT
SET @Counter = 0
-----------Populate the table with 15 minute intervals between 2012 and 2017
WHILE @Counter <= 175299
BEGIN
INSERT INTO Tally (N) VALUES (@Counter) SET @Counter = @Counter + 1
END
-----------Build the CalendarDT Table
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id('CalendarDT') AND OBJECTPROPERTY(id, 'IsTable') = 1)
DROP TABLE CalendarDT;
DECLARE @StartDT DATETIME;
SELECT @StartDT = '2012-01-01T00:00:00';
SELECT DATEADD(mi,v.N*15,@StartDT) AS TheDT INTO CalendarDT FROM Tally v WHERE v.N BETWEEN 0 AND 175299;
-----------Creating a clustered index for performance
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id('IDXC_CalendarDT_TheDT') AND OBJECTPROPERTY(id, 'IsIndex') = 1)
DROP INDEX CalendarDT.IDXC_CalendarDT_TheDT;
CREATE CLUSTERED INDEX IDXC_CalendarDT_TheDT ON CalendarDT (TheDT)
GO
-----------Drop the Tally table
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id('Tally') AND OBJECTPROPERTY(id, 'IsTable') = 1)
DROP TABLE Tally;
然後我試圖加入我的訓練表具有以下：
SELECT CalendarDT.TheDT AS [Date], COALESCE(SUM(Workouts.Calories),0) AS CalorieCnt, Workouts.User_ID
FROM CalendarDT
LEFT OUTER JOIN Workouts ON Workouts.Start_Time >= '03/10/2012 08:00:00 AM' AND Workouts.End_Time < '03/10/2012 06:00:00 PM'
AND CalendarDT.TheDT >= '03/10/2012 08:00:00 AM' AND CalendarDT.TheDT <= '03/10/2012 06:00:00 PM'
WHERE Workouts.User_ID IN (SELECT User_ID FROM Team_User WHERE Team_ID = 1)
GROUP BY CalendarDT.TheDT, Workouts.User_ID
ORDER BY CalendarDT.TheDT;
這是接近我已經能夠得出解決方案。但是，我有幾個問題：
1）我還沒有想出如何從JOIN語句中加入Team_Name。
2）CalorieCnt，即使它是由Team_Name而不是User_ID聚合顯示每個時間段相同的值。它不是在每個給定的時間內正確彙總總數，包括那些應該爲0的時間。
我認爲其中一個問題是，我無法比較說08:45有多少卡路里被燃燒：00 AM，因爲當時沒有鍛鍊開始/結束。 我一直在尋找這一段時間，我很難過。任何幫助獲得這些報告爲個人用戶和團隊工作將不勝感激！
「卡路里」中的值是指「15分鐘內消耗的卡路里」或「鍛鍊期間消耗的卡路里」？ – Quassnoi 2012-04-07 20:20:20
Workouts.calories是鍛鍊過程中燃燒的卡路里數。由於Workouts.calories適用於整個鍛鍊，因此該報告不如其準確。並且，生成的報告每15分鐘一次。我意識到這一點。但是，這是我必須處理的數據。而且，確實爲報告增添了價值。 – user1319487 2012-04-07 20:21:47
