关于H3 BPM数据库如何实现排序取数据的问题

问题：

在打印模板中获取子表内容，可从数据库中取数据，而当前项目数据库里面数据按年度录入，但是只需要显示近3年的数据，插件如何实现排序取数据？

解决方法：

1、先直接写一个SQL语句，把近3年排序后的数据读取出来

2、在调用子表接口加载数据

3、示例：

var monthly = DateTime.Now.Month;

var selectsql = string.Format(@"SELECT

t1.Yearly,

t1.Monthly,

t1.BudgetUnitName,

t1.BudgetUnitCode,

t1.BudgetItemName,

t1.BudgetItemCode,

t1.Budget

FROM XL_YS_BudgetPay t1

WHERE t1.Yearly = {0}

--AND Monthly > {1}

AND t1.BudgetUnitCode = '{2}'

AND BudgetItemCode = '{3}'

ORDER BY Monthly", yearly, monthly, budgetunitcode, budgetitemcode);

var dt = OThinker.H3.WorkSheet.AppUtility.Engine.Query.QueryTable(selectsql);

var list = new List();

var monthlist = new List { "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "December" };

if (dt.Rows.Count > 0)

{

//DeptCostBudgetInfo 为子表名称

BizObjectSchema childSchema = this.ActionContext.Schema.GetProperty("DeptCostBudgetInfo").ChildSchema;

var bizObject = new BizObject(this.ActionContext.Engine, childSchema, this.ActionContext.User.UserID);

bizObject["DataType"] = "原始";

bizObject["BudgetItemName"] = dt.Rows[0]["BudgetItemName"].ToString();

bizObject["BudgetItemCode"] = dt.Rows[0]["BudgetItemCode"].ToString();

var bizObject2 = new BizObject(this.ActionContext.Engine, childSchema, this.ActionContext.User.UserID);

bizObject2["DataType"] = "修改";

bizObject2["BudgetItemName"] = dt.Rows[0]["BudgetItemName"].ToString();

bizObject2["BudgetItemCode"] = dt.Rows[0]["BudgetItemCode"].ToString();

for (int i = 0; i < monthlist.Count; i++)

{

bizObject[monthlist] = dt.Rows["Budget"].ToString();

bizObject2[monthlist] = dt.Rows["Budget"].ToString();

}

list.Add(bizObject);

list.Add(bizObject2);

}

if (bos != null)

{

if (bos.Length > 1)

{

list.AddRange(bos);

}

}

this.ActionContext.InstanceData["DeptCostBudgetInfo"].Value = list.ToArray();

ActionContext.InstanceData.Submit();
