我被困了两周以获得解决方案。
我正在开发一个小型应用程序，它是一个呼叫日志系统。我的问题是当我想搜索我的日志表单时，不会返回数据。我已经检查了我的存储过程查询。我可以成功运行它，但我不知道如何将我的参数回调到后面的代码中。任何人都可以给我一些例子。
这是我的存储过程：
ALTER PROCEDURE [dbo].[T_FILTER]
(
@Call_LogID int= null,
@StarDate datetime= null ,
@EndDate datetime =null,
@Log_code char(20)= null
)
AS
Select Call_LogID ,Log_status ,Log_code ,Log_TypeApp ,Log_Branch ,Log_TypeCust ,Log_name
From Call_Log_Service Where EntryTime BETWEEN convert(Datetime,@StarDate,102)
AND convert(Datetime,@EndDate,102)
AND (Call_logID LIKE '%@Call_logID')
AND (Log_code Like '%@Log_code')
ORDER BY Call_LogID
这是我的代码背后的代码

答案 0 :(得分：1)
这样的事情怎么样：
using System.Data;
using System.Data.SqlClient;
int callLogId = 0;
DateTime startDate = DateTime.Now;
DateTime endDate = DateTime.Now;
string logCode = "";
string connectionString = "YourConnectionString";
using (SqlConnection connection = new SqlConnection(connectionString))
{
SqlCommand cmd = new SqlCommand("T_FILTER", connection);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("Call_LogID",callLogId);
cmd.Parameters.AddWithValue("StarDate",startDate);
cmd.Parameters.AddWithValue("EndDate",endDate);
cmd.Parameters.AddWithValue("Log_code",logCode);
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
//do something
}
dr.Dispose();
cmd.Dispose();
}
我注意到存储过程中的一个参数被称为'StarDate' - 不确定这是否是拼写错误并且应该是'StartDate'？
