返回最小行数（）SQL

这可能是我提出过的最笨拙的问题。我必须使用一个只读帐户，所以我不能使用临时表或任何使这更容易的东西。目标是在

sumpiesesstrapped=maxSum

时返回

MIN（RowNum）

。我已经尝试将整个查询添加到另一个子查询中，试图返回

MIN（RowNum）

但是，它是一对多，与主键

JobNo

绑定，当我将它绑定到

JobNo

和

StepNo

时，它给出的结果与下面的结果相同

SELECT
JobNo,
StepNo,
sumPiecesScrapped,
maxSum,
CASE
WHEN sumPiecesScrapped = maxSum THEN ROW_NUMBER() OVER(PARTITION BY JobNo ORDER BY JobNo, StepNo)
ELSE 0
END AS RowNum
FROM
(
    SELECT
    JobNo,
    StepNo,
    sumPiecesScrapped
    FROM
    (   
            SELECT
            JobNo,
            StepNo,
            SUM(PiecesScrapped) as sumPiecesScrapped
            FROM
            (
                SELECT
                JobNo,
                StepNo,
                PiecesFinished,
                PiecesScrapped
                FROM TimeTicketDet
            ) tt2

            GROUP BY JobNo, StepNo
    ) tt3
    GROUP BY JobNo, StepNo, sumPiecesScrapped
) tt4

LEFT JOIN
(
    SELECT
    JobNo as tt5JobNo,
    MAX(PiecesScrapped) as maxSum
    FROM
    (
        SELECT
        JobNo,
        PiecesScrapped
        FROM TimeTicketDet
    ) tt5
    GROUP BY JobNo
) tt5
ON tt5.tt5JobNo = tt4.JobNo


WHERE tt4.JobNo = '12345'

结果：

如果没有一些表格定义和你想要实现的目标的清晰性，我就无法理解这一点。但MIN（行号）始终为1.：）你说不能使用临时表是什么意思？每个用户都可以访问

tempdb

您应该仍然能够使用类似

CREATE TABLE#temp（someColumn varchar（10））的语法

或（可选）表变量。@SeanLange在TimeTicketSet表中，JobNo是主键，每个JobNo可以有多个步骤。我试图在没有cte的情况下使用SQL来计算第一次使用SUMPEGEESSCRAPPED=maxSum的时间。@Larnu UHHHHHH我当时肯定觉得需要写访问权限。让我去做一些测试。如果我尝试了所有这些解决方法，并且可以使用tempdb，我会觉得很愚蠢。为什么没有CTE呢？对于CTE，您肯定不需要写访问权限。如果没有一些表定义和您试图实现的目标的明确性，我就无法理解这一点。但MIN（行号）始终为1.：）你说不能使用临时表是什么意思？每个用户都可以访问
