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

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＃No Dara返回..

Answer 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。

Answer 2

我不知道代码有什么问题，但是我做了一些更改而且没有工作。我现在改变了命令文本而不是使用过程我正在使用这个查询，当我运行时返回记录SQL Management Studio。

现在它运作良好。

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;

存储过程在MS Management Studio中返回数据。使用C＃调用时不返回任何数据
