我已经使用 SQL PROILER 检查了 C# 发送到 SQL Server 的哪些值..

exec SerachTickets @StoreID=1,@StatusID=N'',@CustomerName=N'',@TicketNo=N'',@StratDate='1900-01-01 00:00:00',@ESTDate= '1900-01-01 00:00:00',@StaffID=0,@ServiceItemID=N''

在 MS Managment Studio 中运行此查询时，它返回所需的结果，但在 C# 中没有 Dara 返回..

【参考方案1】：

使用SqlCommand cmd =new SqlCommand(sqlCon) 代替SqlCommand cmd =sqlCon.CreateCommand()。

并在调试期间检查适配器是否填充数据集。

【讨论】：

我想你想说 SqlCommand = new SqlCommand("SerachTickets",sqlCon);...不，这不行

【参考方案2】：

我不知道代码出了什么问题，但我做了一些更改，但它不工作SQL 管理工作室。

现在运行良好。

string strCommand = "exec SerachTickets @StoreID=" + Session["StoreID"] + ",@StatusID=N'" + Request.QueryString["sid"] + "',@CustomerName=N'" + Request .QueryString["cname"] + "',@TicketNo=N'" + Request.QueryString["tno"] + "',@StratDate='" + dtStart + "',@ESTDate='" + dtEst + " ',@StaffID=" + intAssign + ",@ServiceItemID=N'" + Request.QueryString["itemid"] + "'";

cmd.CommandText = strCommand;
