当数据是阿拉伯语，使用动态查询参数

选择查询不起作用在asp.net c＃代码里面Visual Studio，我开发了一个搜索按钮。当我尝试运行代码时，它在编写代码时不会返回任何内容。我认为问题在于stat_leger是用阿拉伯语写的。当数据是阿拉伯语，使用动态查询参数

SqlParameter[] para = new SqlParameter[4]; 
    para[0] = new SqlParameter("@stat_leger", ddlACCcode.SelectedValue); 
    para[1] = new SqlParameter("@branch", DDLBranch.SelectedValue); 
    para[2] = new SqlParameter("@from", db.getDate(txtFrom.Text)); 
    para[3] = new SqlParameter("@to", db.getDate(txtTo.Text)); 

DataTable dtreport = db.SelectCmdText("Select * from PostedVoucher join transactions on trans_code = stat_trans_code where stat_leger = @stat_leger and [email protected] and stat_date between @from and @to ORDER BY stat_date ", para); 

GridView1.DataSource = dtreport; 
GridView1.DataBind(); 
float GTotal = 0; 
float GTotalcrd = 0; 
float GTotaldeb = 0;

它工作时，我试图写在sql服务器内相同的选择。但与阿拉伯文我使用N它是返回记录。

Select * from PostedVoucher join transactions on trans_code =  
    stat_trans_code 
     where stat_sub_leger = N'الصندوق' and branch= N'الفرع الرئيسي' and stat_date between '2013-12-05 00:00:00.000' AND '2013-12-05 00:00:00.000' ORDER BY stat_date ;

我试图把它写在选择但仍无法正常工作：

  DataTable dtreport = db.SelectCmdText("Select * from PostedVoucher join transactions on trans_code = stat_trans_code where stat_sub_leger = N'@stat_sub_leger' and [email protected] and stat_date between @from and @to ORDER BY stat_date ", para);

检查字符集的字段或表的匹配。使用报价... – 2015-03-02 11:47:55

试图改变自己的查询，样品：

Select * from PostedVoucher join transactions on trans_code = stat_trans_code where stat_leger like '%' + @stat_leger + '%' OR branch like '%' + @branch + '%' AND stat_date between @from and @to ORDER BY stat_date ", para);

我认为它可能以这种方式工作：

para[0] = new SqlParameter("@stat_leger", "N'"+ddlACCcode.SelectedValue+"'")

然后使用您的查询自asp.net中：

DataTable dtreport = db.SelectCmdText(
    "Select * from PostedVoucher join transactions on trans_code = stat_trans_code where stat_sub_leger = N'@stat_sub_leger' and [email protected] and stat_date between @from and @to ORDER BY stat_date ", 
    para);

然后它总是建议打印最终SQL命令来查看是否SQL命令的正确形式
