关于控制报表字段的精度几种方法

    1.BOS配置

    2.插件代码干预

            string deciamlControlFieldQty = "FQTYDeciaml";
            List<DecimalControlField> list=new List<DecimalControlField>();
            list.Add(new DecimalControlField(deciamlControlFieldQty, "purPro"));
            base.ReportProperty.DecimalControlFieldList = list;

            select ROW_NUMBER() over (order by FNAME)  FIDENTITYID, FNAME,FNUMBER,purOrder        
            .......  ,2 FQTYDeciaml

    3.SQL控制

         CONVERT(DECIMAL(13,2), filed) 别名
