我有一个需要执行运行总和的查询 在日期/时间和班次。
班次是上午6:00到下午4:30 和下午6:00到4:30。
我正在使用的查询引擎是SQLite。
我遇到以下SQL查询的问题。您将在下面看到该查询 和当前的结果，然后是期望的结果。 按日期/时间/班次顺序排列当前结果 导致总QTY列也显示不正确的数据。
是否有人在此之前遇到过这个问题，并且可能 把我推向正确的方向。我愿意接受建议 即使我必须在没有查询的情况下对数据进行排序，最好使用 的java。
SELECT tdate, qty, shift,
(
SELECT sum( b.qty )
FROM table1 AS b
WHERE (
(
( b.id <= a.id AND b.shift = a.shift)
)
)
GROUP BY date(b.tdate)
)
AS bo_total
FROM table1 AS a
ORDER BY date( a.tdate ) ASC, a.shift ASC
当前结果

我认为你可以通过减去5个小时并将其作为比较日期来做你想做的事。这样，凌晨4点将与下午11点在同一“日”。之前的日期。我认为以下是在SQLite中做到的：
SELECT tdate, qty, shift,
(SELECT sum( b.qty )
FROM table1 AS b
WHERE b.id <= a.id AND b.shift = a.shift and
date(b.tdate, '-5 Hours') = date(a.tdate, '-5 Hours')
)
AS bo_total
FROM table1 AS a
ORDER BY date(a.tdate ) ASC, a.shift ASC;
答案 1 :(得分：0)
此查询首先计算班次开始的日期，这使得班次比较更容易：
WITH a AS
(SELECT ID,
qty,
tdate,
shift,
CASE
WHEN time(tdate) BETWEEN '05:30' AND '17:00'
THEN date(tdate) || ' first'
WHEN time(tdate) >= '17:30' THEN date(tdate) || ' second'
WHEN time(tdate) <= '05:00' THEN date(tdate, '-1 day') || ' second'
END AS ShiftID
FROM Table1)
SELECT tdate,
qty,
shift,
(SELECT sum(qty)
FROM a AS b
WHERE b.ShiftID = a.ShiftID
AND b.tdate <= a.tdate
) AS bo_total
FROM a
ORDER BY tdate
如果您的SQLite驱动程序早于3.8.3，请使用视图而不是CTE。
