SQL C#存储过程插入到

我想在数据库Aktiendepot中的tblPositions表的新行中插入值。当我运行它时，什么都不会发生。传递给方法的值应该是正确的

aspx.cs

protected void StockBuy_Click(object sender, EventArgs e)
{
    Methods CustomMethods = new Methods();
    CustomMethods.BuyStock(sSymbol, sCompany, sExchange, iQuantity, dPrice, sUsername);
}

方法.cs

public void BuyStock(string sSymbol, string sCompany, string sExchange, int iQuantity, double dPrice, string sUsername) //Inserts stock information to database
{
        SqlConnection con = new SqlConnection("user id=admin;" +
                                          "password=1337passwort;server=localhost;" +
                                          "database=Aktiendepot; " +
                                          "connection timeout=30"); //Establishes Connection
        SqlCommand InsertStockInformation = new SqlCommand("StockBuy", con);
        InsertStockInformation.CommandType = CommandType.StoredProcedure;
        SqlParameter quantity = new SqlParameter("@quantity", SqlDbType.Int, 5,iQuantity.ToString());
        quantity.Direction = ParameterDirection.Input;
        InsertStockInformation.Parameters.Add(quantity);
        SqlParameter symbol = new SqlParameter("@symbol", SqlDbType.VarChar, 50, sSymbol);
        symbol.Direction = ParameterDirection.Input;
        InsertStockInformation.Parameters.Add(symbol);
        SqlParameter company = new SqlParameter("@company", SqlDbType.VarChar, 30, sCompany);
        company.Direction = ParameterDirection.Input;
        InsertStockInformation.Parameters.Add(company);
        SqlParameter exchange = new SqlParameter("@exchange", SqlDbType.VarChar, 20, sExchange);
        exchange.Direction = ParameterDirection.Input;
        InsertStockInformation.Parameters.Add(exchange);
        SqlParameter buymktprice = new SqlParameter("@buymktprice", SqlDbType.Float, 50, dPrice.ToString());
        buymktprice.Direction = ParameterDirection.Input;
        InsertStockInformation.Parameters.Add(buymktprice);
        SqlParameter username = new SqlParameter("@username", sUsername);
        username.Direction = ParameterDirection.Input;
        InsertStockInformation.Parameters.Add(username);
        con.Open();
        InsertStockInformation.ExecuteNonQuery();
        con.Close();
}

下面是我如何创建表的

create table tblPositions (PosID int NOT NULL identity(1,1), PosQuantity int NOT NULL, PosSymbol varchar(10) NOT NULL, PosCompany varchar(30) NOT NULL, PosExchange varchar(20) NOT NULL,
                       PosBuyMktPrice float NOT NULL, PosBuyDate date NOT NULL, FK_PosUsername varchar(50) NOT NULL foreign key references tblUsers(UserUsername),
                       primary key (PosID));

这是存储过程

    ALTER PROCEDURE [dbo].[StockBuy]
(
@username as varchar(50),
@quantity as int,
@symbol as varchar(50),
@company as varchar(30),
@exchange as varchar(20),
@buymktprice as float
)
AS
INSERT INTO tblPositions (PosQuantity,PosSymbol,PosCompany,PosExchange,PosBuyMktPrice,PosBuyDate,FK_PosUsername) VALUES (@quantity,@symbol,@company,@exchange,@buymktprice,GETDATE(),@username)

保留断点并检查代码的执行流程

    catch(SqlException ex)
    {
        //Error
    }

上面是您的

块，其中没有捕获错误。可能产生的错误在

试试这段代码

try
     {
       SqlConnection con = new SqlConnection("user id=admin;" +
       "password=1337passwort;" +"server=localhost;" +
        "database=Aktiendepot; " +
         "connection timeout=30"); //Establishes Connection
     SqlCommand InsertStockInformation = new SqlCommand("StockBuy", con);
     InsertStockInformation.CommandType = CommandType.StoredProcedure;
     InsertStockInformation.Parameters.Add("@quantity",SqlDbType.Int).Value=quantity;
     InsertStockInformation.Parameters.Add("@symbol",SqlDbType.NVarChar,50).Value=sSymbol;
     InsertStockInformation.Parameters.Add("@company",SqlDbType.NVarChar,30).Value=sCompany;
     InsertStockInformation.Parameters.Add("@exchange",SqlDbType.NVarChar,20).Value=sExchange;
     InsertStockInformation.Parameters.Add("@buymktprice",SqlDbType.Float,50).Value=dPrice;
      InsertStockInformation.Parameters.Add("@username",SqlDbType.NVarChar,50).Value=sUsername;

con.Open();
 InsertStockInformation.ExecuteNonQuery();


con.Close();
 }
 catch(SqlException ex)
{
  MessageBox.Show(ex.ToString());

}

试试这个代码

try
     {
       SqlConnection con = new SqlConnection("user id=admin;" +
       "password=1337passwort;" +"server=localhost;" +
        "database=Aktiendepot; " +
         "connection timeout=30"); //Establishes Connection
     SqlCommand InsertStockInformation = new SqlCommand("StockBuy", con);
     InsertStockInformation.CommandType = CommandType.StoredProcedure;
     InsertStockInformation.Parameters.Add("@quantity",SqlDbType.Int).Value=quantity;
     InsertStockInformation.Parameters.Add("@symbol",SqlDbType.NVarChar,50).Value=sSymbol;

     InsertStockInformation.Parameters.Add("@buymktprice",SqlDbType.Float,50).Value=dPrice;
      InsertStockInformation.Parameters.Add("@username",SqlDbType.NVarChar,50).Value=sUsername;

con.Open();
 InsertStockInformation.ExecuteNonQuery();


con.Close();
 }
 catch(SqlException ex)
{
  MessageBox.Show(ex.ToString());
