16.3、 表单插件，读写数据库， DBUtils，IEnumerable，返回

业务场景：销售出库单，点击按钮，执行sq后，返回值，再循环赋值，单据体获取全部物料

续

16.2

1、注释上一节代码

2、

                //DBUtils.ExecuteEnumerable 执行sql
                IEnumerable<IDataRecord> itemDataTable = DBUtils.ExecuteEnumerable(this.Context, "/*dialect*/select FMATERIALID,FNumber from T_BD_MATERIAL");
                
                //循环
                int i = 0;
                foreach(IDataRecord drItem in itemDataTable)
                {
                    //新增行
                    this.View.Model.CreateNewEntryRow("FEntity");
                    
                    //给基础资料物料,赋值
                    this.View.Model.SetValue("FMaterialID", drItem["FMATERIALID"].ToString(), i);
                    
                    //调用物料,值更新
                    this.View.InvokeFieldUpdateService("FMaterialID", i);
                    
                    //给备注,赋值
                    this.View.Model.SetValue("FEntrynote", drItem["FNumber"].ToString(), i);
                    
                    i++;
                }

4、重新生成dll

5、最终效果，重新打开销售出库单，点测试按钮，带出全部的物料，跟上一节效果一样
