我得到的问题是它只输出运行总计,所以我在页面底部的ONCE得到以下内容,但仅此而已：
Work Complete Totals
Quoted Total : £1460.00
Parts Total : £541.43
Profit Total : £918.57
pricequotedtotal partpricetotal profittotal month
1460 541.43 918.5699999999998 NULL
我的表格布局如下：

以下是一个示例行：

最佳答案
你需要改变它
DATE_FORMAT('%Y-%m',completeddate)
至
DATE_FORMAT(completeddate,'%Y-%m')
这就是你在月份列中得到NULL的原因,因此只有一行.
