插入后,在数据库中只插入一个字符串"string"

Question

下面是我的表截图:

插入后的数据

C#中的代码

SqlConnection con = new SqlConnection(connectionsession.Con);
con.Open();
SqlCommand cmd = new SqlCommand("finalinsert", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@fid", SqlDbType.Int)).Value = flightsession.Sflightid;
cmd.Parameters.Add(new SqlParameter("@fcid", SqlDbType.Int)).Value = flightsession.Sflightcostid;
cmd.Parameters.Add(new SqlParameter("@ftid", SqlDbType.Int)).Value = flightsession.Sflighttimingid;
cmd.Parameters.Add(new SqlParameter("@frdn", SqlDbType.Date)).Value = DateTime.Now.ToString("dd-MM-yyyy");
cmd.Parameters.Add(new SqlParameter("@ford", SqlDbType.Date)).Value = flightsession.Regdate;
cmd.Parameters.Add(new SqlParameter("@uid", SqlDbType.Int)).Value = loginsession.Auser;
cmd.Parameters.Add(new SqlParameter("@paid", SqlDbType.Int)).Value = "1";
cmd.Parameters.Add(new SqlParameter("@source", SqlDbType.VarChar)).Value = flightsession.Sscource;
cmd.Parameters.Add(new SqlParameter("@destination", SqlDbType.VarChar)).Value = flightsession.Sdestination;
cmd.Parameters.Add(new SqlParameter("@fn", SqlDbType.VarChar)).Value = flightsession.Sflightname;
cmd.Parameters.Add(new SqlParameter("@fc", SqlDbType.VarChar)).Value = flightsession.Total;
cmd.Parameters.Add(new SqlParameter("@fty", SqlDbType.VarChar)).Value = flightsession.Stype;
cmd.Parameters.Add(new SqlParameter("@fcl", SqlDbType.VarChar)).Value = flightsession.Sflightclass;
cmd.Parameters.Add(new SqlParameter("@ft", SqlDbType.Time)).Value =flightsession.Sflighttime;
cmd.ExecuteNonQuery();
MessageBox.Show("Succesful");
con.Close();
flightreceipt ob18 = new flightreceipt();
ob18.ShowDialog();
this.Hide();

在SQL Server 2008中创建过程的代码

ALTER procedure [dbo].[finalinsert] @fid int,@fcid int,@ftid int,@frdn date,@ford date,@uid int,
@paid int,@source varchar,@destination varchar,@fc varchar,@fty varchar,@fcl varchar,@ft time(7) ,@fn varchar
AS
INSERT INTO [shangrila].[dbo].[flight_reg_table]
           ([flight_id]
           ,[flight_cost_id]
           ,[flight_time_id]
           ,[flight_reg_date_now]
           ,[flight_on_reg_date]
           ,[user_id]
           ,[paid]
           ,[source]
           ,[destination]
           ,[flight_name]
           ,[flight_cost]
           ,[flight_type]
           ,[flight_class]
           ,[flight_time])
     VALUES
           (@fid,
           @fcid,
           @ftid,
           @frdn,
           @ford,
           @uid,
           @paid,
           @source,
           @destination,
           @fn,
           @fc,
           @fty,
           @fcl,
           @ft)

我试图找出原因!但我被卡住了.记住我插入的所有格式都是字符串.谢谢.

在您的sproc中,您的VARCHAR需要具有与之关联的长度,例如VARCHAR(50).默认长度为1,因此SQL只向您的sproc发送一个字符.

ALTER procedure [dbo].[finalinsert]
     @fid int
    ,@fcid int
    ,@ftid int
    ,@frdn date 
    ,@ford date
    ,@uid int
    ,@paid int
    ,@source varchar(50)
    ,@destination varchar(50)
    ,@fc varchar(50)
    ,@fty varchar(50)
    ,@fcl varchar(50)
    ,@ft time(7)
    ,@fn varchar(50)
AS

您可能还需要更改调用中的数据类型以包括长度,但ADO.NET 可能会正确处理它.
