Question

我有一个SQL函数，它从多个记录中收集人工时间，并使用STUFF(CAST AS VARCHAR(20))将它们连接到临时表中的单个列。

我的问题是我的表中的人工值是以小时为单位并向下舍入到7位小数，我想将这些值转换为分钟并将它们舍入到2位小数，然后将它们填充到临时表中。

更新：忘记提及，我正在使用SQL Server 2008 R2

这是我的代码。

  @site nvarchar(20)
  ,@item nvarchar(30)
  ,@enviro nvarchar(30))
RETURNS nvarchar(MAX)
AS
BEGIN
    DECLARE @LbrHours AS nvarchar(MAX) = ''

    IF @enviro = 'Test'
    BEGIN
        IF @site = 'Arborg'
        BEGIN
            SET @LbrHours = STUFF((SELECT ',' + CAST(jrt.run_lbr_hrs AS VARCHAR(20))
                            FROM Arborg_Test_App.dbo.jobroute AS jbr
                                INNER JOIN Arborg_Test_App.dbo.job AS job
                                    ON job.job = jbr.job 
                                    AND job.suffix = jbr.suffix
                                INNER JOIN Arborg_Test_App.dbo.item AS itm
                                    ON itm.job = job.job
                                INNER JOIN Arborg_Test_App.dbo.jrt_sch AS jsh
                                    ON jbr.job = jsh.job 
                                    AND jbr.suffix = jsh.suffix 
                                    AND jbr.oper_num = jsh.oper_num
                                LEFT OUTER JOIN Arborg_Test_App.dbo.jrt_sch AS jrt
                                    ON jbr.job = jrt.job
                                    AND jbr.suffix = jrt.suffix
                                    AND jbr.oper_num = jrt.oper_num
                            WHERE  job.suffix = '0' and job.type = 'S' AND itm.item IS NOT NULL
                                AND itm.item = @item 
                                AND jbr.suffix = CASE -- Return Standard cost if Standard Operation exist, else return current cost
                                                    WHEN itm.cost_type = 'S'
                                                        THEN '1' -- '1' for standard operation
                                                    ELSE '0' -- '0' for current operations
                                                  END
                            ORDER BY itm.item, jbr.oper_num
                            FOR XML PATH('')), 1, 1, '')
            END 
        END

    RETURN @LbrHours
END

jrt.run_lbr_hrs是包含ERP表格中以小时为单位的人工时间的列。如何在现有的STUFF(CASE AS NVARCHAR)中将其乘以60并将其四舍五入为2位小数？

Answer 1

CAST到十进制，在点之后有2个值，然后到varchar

CAST(CAST(jrt.run_lbr_hrs * 60 AS DECIMAL(10, 2)) AS VARCHAR(20))

将小数尺寸更改为您需要的尺寸

Answer 2

试试这个Str (jrt.run_lbr_hrs * 60, 2)

在SQL中乘以值，向下舍入和CAST选择
