SQL Datepart（week），ORDER BY year？

Question

我在這裏使用以下查詢來獲取我的數據並顯示每週價值，但是，當有新的一年，結果將顯示周50, 51, 52 of 2016和周1, 2, 3 of 2017例如，它將order by週數導致1,2,3,50,51,52這意味着2017年的結果出現在2016年之前，我該如何改變這一點？

SELECT 
    DATEPART(wk, date) AS number, 
    SUM((kg * rep * sett)) AS weight, 
    SUM(kg/max * rep * sett) AS avg, 
    SUM((rep * sett)) AS reps, 
    MAX(kg/max) AS peak 
FROM 
    Test 
WHERE 
    date BETWEEN @0 AND @1 AND exercise < 4 
GROUP BY DATEPART(wk, date) 

Answer 1

也許不是最完美的解決方案，但你可以只包括當年在場上你GROUP BY：

SELECT 
    CONVERT(VARCHAR,DATEPART(year, date)) + '_' + CONVERT(VARCHAR,DATEPART(wk, date)) AS Year_Week, 
    SUM((kg * rep * sett)) AS weight, 
    SUM(kg/max * rep * sett) AS avg, 
    SUM((rep * sett)) AS reps, 
    MAX(kg/max) AS peak 
FROM 
    Test 
WHERE 
    date BETWEEN @0 AND @1 AND exercise < 4 
GROUP BY CONVERT(VARCHAR,DATEPART(year, date)) + '_' + CONVERT(VARCHAR,DATEPART(wk, date)) 
ORDER BY CONVERT(VARCHAR,DATEPART(year, date)) + '_' + CONVERT(VARCHAR,DATEPART(wk, date)) 

或（可能更好），只是將其視爲完全獨立的領域：

SELECT 
    DATEPART(year, date) AS Year, 
    DATEPART(wk, date) AS Week, 
    SUM((kg * rep * sett)) AS weight, 
    SUM(kg/max * rep * sett) AS avg, 
    SUM((rep * sett)) AS reps, 
    MAX(kg/max) AS peak 
FROM 
    Test 
WHERE 
    date BETWEEN @0 AND @1 AND exercise < 4 
GROUP BY DATEPART(year, date), DATEPART(wk, date) 
ORDER BY DATEPART(year, date), DATEPART(wk, date) 

Answer 2

你可以按上年度部分的合計添加訂單：

SELECT 
    DATEPART(wk, date) AS number, 
    SUM((kg * rep * sett)) AS weight, 
    SUM(kg/max * rep * sett) AS avg, 
    SUM((rep * sett)) AS reps, 
    MAX(kg/max) AS peak 
FROM 
    Test 
WHERE 
    date BETWEEN @0 AND @1 AND exercise < 4 
GROUP BY DATEPART(wk, date) 
order by max(datepart(year,date)), number; 

以上但是聚集來自同一個星期號一起的數據，即使它們在不同的年份下降（可能不是你想要什麼）。如果您想分開保存不同年份的數據，可以在輸出中添加年份列。

SELECT 
    datepart(year,date) as year, 
    DATEPART(wk, date) AS number, 
    SUM((kg * rep * sett)) AS weight, 
    SUM(kg/max * rep * sett) AS avg, 
    SUM((rep * sett)) AS reps, 
    MAX(kg/max) AS peak 
FROM 
    Test 
WHERE 
    date BETWEEN @0 AND @1 AND exercise < 4 
GROUP BY datepart(year,date), DATEPART(wk, date) 
order by year, number;
