Question

我有以下内容返回给定类型作业的总发票金额。我现在想把它分解成月总数。关于如何处理这个问题的任何提示

SELECT     dbo.jm_job_type.job_type_desc, SUM(dbo.jm_invoice.invoice_amount) AS 'inv tot'
FROM         dbo.jm_invoice INNER JOIN
                  dbo.jm_job ON dbo.jm_invoice.job_no = dbo.jm_job.job_no INNER JOIN
                  dbo.jm_job_type ON dbo.jm_job.job_type_no = dbo.jm_job_type.job_type_no
GROUP BY dbo.jm_job_type.job_type_desc

Answer 1

在Group By中使用SQL Server datepart函数，如下所示：

GROUP BY 
    DatePart(yy, dbo.jm_invoice.some_date), 
    DatePart(mm, dbo.jm_invoice.some_date), 
    dbo.jm_job_type.job_type_desc

Answer 2

“楼”到月（最有效的方式只获得月份+年）然后GROUP BY那个“

GROUP BY DATEADD（月，DATEDIFF（月，0，dbo.jm_invoice.YourDate），0）

所以它会是：

SELECT     dbo.jm_job_type.job_type_desc,
           DATEADD(month,DATEDIFF(month,0, dbo.jm_invoice.YourDate),0) AS MonthYear,
           SUM(dbo.jm_invoice.invoice_amount) AS 'inv tot'
FROM         dbo.jm_invoice INNER JOIN
                  dbo.jm_job ON dbo.jm_invoice.job_no = dbo.jm_job.job_no INNER JOIN
                  dbo.jm_job_type ON dbo.jm_job.job_type_no = dbo.jm_job_type.job_type_no
GROUP BY dbo.jm_job_type.job_type_desc, 
         DATEADD(month,DATEDIFF(month,0, dbo.jm_invoice.YourDate),0)

Answer 3

将年份和月份字段添加到SELECT列表中，并将其添加到GROUP BY列表

SQL SUM（）在一个月的月度报告中
