能直接对 数据集中的字段求和吗? #20
Comments
sum(xly_statistics_stock.select(QTY))这样不行 |
数值一直是0,但明明这个字段不为0 |
正确的写法是:xly_statistics_stock.sum(QTY) |
最新的2.0.8-SNAPSHOT也支持sum(xly_statistics_stock.select(QTY))这样的写法,请测试。 |
v_warerecord.sum(gradesA*QTY)这样报错 |
v_warerecord.sum(gradesA*QTY) 这是什么意思?两个属性相乘?ureport2可不支持这种写法,如果是,那正解的写法应该是: |
v_warerecord.sum(gradesA) * v_warerecord.sum(QTY)这样达不到我的需求,我需要每条记录里的gradesA、QTY这两个字段相乘,再求和 |
嗯,UReport2不支持这么做。 |
嗯,已经这样处理了 |
