我一直在刺伤这个。查看fe选项以显示以下结果集。想要显示ProdOp，OpSUM，然后PCT（我们将从总时间减去t.opcode LL中获取）。 这是漫长的一天，我想它可能是因为潜艇不能返回多行？如果没有其他方式接近？交叉加入？
预期结果（具有实际百分比的PCT）我们从TimeSUM查询获得百分比，即7:59然后除以每个OpSUM。
ProdOp OpSUM PCT
BB 0:20 4.2%
DF 1:15 15.6%
HF 0:10 2.1%
HR 0:25 5.2%
JT 0:14 2.9%
MM 0:27 5.6%
NW 0:39 8.1%
PE 0:21 4.4%
PX 0:45 9.4%
SP 2:52 35.9%
SS 0:31 6.5%

我的计算方法不同，但我认为它们是正确的 - 我使用excel数据透视表检查它们以获得总计的百分比。试试这个：
SELECT
OpCode,
convert(varchar, dateadd(s,sum(datediff(second,StartTime,FinishTime)), 0), 114),
SUM(datediff(second, StartTime, FinishTime)) * 100.0 / convert(decimal, t.total)
FROM
MaintTimeLog
CROSS JOIN (SELECT SUM(datediff(second,StartTime,FinishTime)) as total FROM MaintTimeLog) t
GROUP BY
OpCode,
t.total
convert函数本身使用dateadd函数，仅用于格式化结果。您的初始尝试是对格式化结果的组件进行数学计算，而此版本使用convert函数以格式化值返回结果，而不修改基础值。格式114指定所需的日期格式。

@Alan我会给你充分的信任。我玩弄了你的方法，并且能够准确地生产出我想要的东西。我想使用下面的日期时间格式的原因是出于清晰的报告原因。感谢您对此的帮助。我最初认为某处需要交叉加入。再次，谢谢和欢呼！
