問題：

在打印模板中獲取子表內容，可從數據庫中取數據，而當前項目數據庫里面數據按年度錄入，但是只需要顯示近3年的數據，插件如何實現排序取數據？

解決方法：

1、先直接寫一個SQL語句，把近3年排序后的數據讀取出來

2、在調用子表接口加載數據

3、示例：

varmonthly = 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

????? ????????????????????????????????????????WHEREt1.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 = newList<BizObject>();

?

var monthlist = newList<string> { "Jan", "Feb", "Mar","Apr", "May", "Jun", "Jul","Aug", "Sep", "Oct", "Nov","December" };

?

if (dt.Rows.Count > 0)

{

//DeptCostBudgetInfo 為子表名稱

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

?

varbizObject = 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();

?

varbizObject2 = 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();
