Question

这是我的原始Db的样子：

public bool inStringAll(string needle, string haystack)
{
    needle = Regex.Replace(needle.ToLower(), @"\r\n", string.Empty);
    haystack = Regex.Replace(haystack.ToLower(), @"\r\n", string.Empty);

    Console.WriteLine($"looking for {needle} in {haystack");

    string[] needleArr = needle.Split(' ');
    string[] haystackArr = haystack.Split(' ');

    for(int j = 0; j < needleArr.Length; j++)
        Console.WriteLine(needleArr[j]);

    int percent = 0;
    int increment;
    bool decision = false;

    if (needleArr.Length > 3)
         increment = 100 / 3;
    else increment = 100 / needleArr.Length;

    for (int i = 0; i < 3; i++)
    {
        for (int j = 0; j < haystackArr.Length; j++)
        {
            Console.WriteLine("looking for " + needle[i] + " in " + haystack[j]);
            if (needleArr[i] == haystackArr[j])
            {
                percent += increment;
            }
        }
    }
    Console.WriteLine($"Percent: {percent}%");

    if (percent >= 50)
        decision = true;

    return decision;
}

这是我用来获得当前结果的代码：

+-------------+----------+---------------------+------+
| StationName | State    | Start_time          | Time |
+-------------+----------+---------------------+------+
| P3          | Downtime | 2018-02-14 13:57:39 | 83   |
+-------------+----------+---------------------+------+
| P4          | Downtime | 2018-02-14 13:57:39 | 118  |
+-------------+----------+---------------------+------+
| P3          | Downtime | 2018-02-15 06:52:51 | 6    |
+-------------+----------+---------------------+------+
| P4          | Downtime | 2018-02-15 06:52:51 | 11   |
+-------------+----------+---------------------+------+
| P2          | Downtime | 2018-02-15 07:04:16 | 60   |
+-------------+----------+---------------------+------+
| P8          | Downtime | 2018-02-15 07:04:16 | 7    |
+-------------+----------+---------------------+------+

我当前的结果是：

SELECT * FROM( SELECT CAST([start_time] as DATE) AS [DATE], State, Sum(Time) AS Downtime, STATIONNAME FROM A6K_Events Where StationName Like 'P%' AND State='Downtime' AND (Dep != 'Event Log Error' OR Dep IS NULL) GROUP BY [start_time],STATIONNAME, State ) AS S PIVOT (sum(Downtime) FOR STATIONNAME IN([P1],[P2],[P3],[P4],[P5],[P6],[P7], [P8],[P9],[P10])) AS PT

我尝试了许多不同的展示位置和方法来将其转换为分钟。我最终遇到了一系列错误，而且我不确定自己在做什么错。下面是我将秒转换为小时数分钟的方法。我不确定这是否与我使用的格式不兼容，或者是否将其放在正确的位置或现在。下面的此Convert函数中的列引用也可能不准确。

+------------+----------+------+------+----+-----+------+------+------+------+------+------+
| DATE       | State    | P1   | P2   | P3 | P4  | P5   | P6   | P7   | P8   | P9   | P10  |
+------------+----------+------+------+----+-----+------+------+------+------+------+------+
| 2018-02-14 | Downtime | NULL | NULL | 83 | 118 | NULL | NULL | NULL | NULL | NULL | NULL |
+------------+----------+------+------+----+-----+------+------+------+------+------+------+
| 2018-02-15 | Downtime | NULL | 60   | 6  | 11  | NULL | NULL | NULL | 7    | NULL | NULL |
+------------+----------+------+------+----+-----+------+------+------+------+------+------+

有人知道实现我的目标的好方法吗，该目标以小时，分钟，秒为单位显示每天每个进程的停机时间？我的“当前结果”粘贴的文本表正是我需要的，而不是秒格式。我将不胜感激，谢谢。

我的预期输出是我的当前结果，但以H：mm：ss

您可以尝试以下查询吗？

SELECT * FROM(
SELECT CAST([start_time] as DATETIME2) AS [DATE], 
State, 
Sum(Time) AS Downtime,
STATIONNAME 

FROM A6K_Events 

Where StationName Like 'P%' AND State='Downtime' 
AND (Dep != 'Event LogError' OR Dep IS NULL)
GROUP BY [start_time],STATIONNAME, State
) AS S
PIVOT (sum(Downtime) FOR STATIONNAME IN([P1],[P2],[P3],[P4],[P5],[P6],[P7], 
[P8],[P9],[P10])) AS PT

输出：

Answer 2

罗斯·布什（Ross Bush）的评论向我指出了我要去的方向，谢谢大家的答复。在我的外部查询中，我需要引用转换时已旋转的列，而不是引用该列的先前名称。

SQL将数据透视结果转换为H：mm：ss
