Question

我正在尝试将这些数据插入到我的数据库表中，但它无法正常工作。有错误表示关键字'Set'附近的语法不正确。实际上这是什么错误？无法知道如何处理这个

            //insert clientID into traderecords.
            SqlCommand sqlinsertCmd = new SqlCommand("INSERT TradeRecords Set ClientID = @clientID", hookUp7);
            sqlinsertCmd.Parameters.Add("@clientID", SqlDbType.Int).Value = clientID;
            sqlinsertCmd.ExecuteNonQuery();
            //insert stockname into traderecords.
            SqlCommand sqlinsertCmd2 = new SqlCommand("INSERT TradeRecords Set StockName = @stockname", hookUp8);
            sqlinsertCmd2.Parameters.Add("@stockname", SqlDbType.Int).Value = stockname;
            sqlinsertCmd2.ExecuteNonQuery();
            //insert amount of unit into traderecords.
            SqlCommand sqlinsertCmd3 = new SqlCommand("INSERT TradeRecords Set Amount = @amountofunit", hookUp9);
            sqlinsertCmd3.Parameters.Add("@amountofunit", SqlDbType.Int).Value = amountofunit;
            sqlinsertCmd3.ExecuteNonQuery();
            //insert total price into traderecords.
            SqlCommand sqlinsertCmd4 = new SqlCommand("INSERT TradeRecords Set TotalPrice = @answer", hookUp10);
            sqlinsertCmd4.Parameters.Add("@answer", SqlDbType.Int).Value = answer;
            sqlinsertCmd4.ExecuteNonQuery();
            //insert current date into traderecords.
            SqlCommand sqlinsertCmd5 = new SqlCommand("INSERT TradeRecords Set CurrentDate = @datetime", hookUp11);
            sqlinsertCmd5.Parameters.Add("@datetime", SqlDbType.Int).Value = datetime;
            sqlinsertCmd5.ExecuteNonQuery();
            //insert price per unit into traderecords.
            SqlCommand sqlinsertCmd6 = new SqlCommand("INSERT TradeRecords Set PricePerUnit = @stockpriceperunit", hookUp12);
            sqlinsertCmd6.Parameters.Add("@stockpriceperunit", SqlDbType.Int).Value = stockpriceperunit;
            sqlinsertCmd6.ExecuteNonQuery();
            //insert payment type into traderecords.
            SqlCommand sqlinsertCmd7 = new SqlCommand("INSERT TradeRecords Set PaymentType = 'Buy'", hookUp13);
            sqlinsertCmd7.Parameters.Add("Buy", SqlDbType.Int).Value = "Buy";
            sqlinsertCmd7.ExecuteNonQuery();
            //insert client nameinto traderecords.
            SqlCommand sqlinsertCmd8 = new SqlCommand("INSERT TradeRecords Set ClientName = @clientname", hookUp14);
            sqlinsertCmd8.Parameters.Add("@clientname", SqlDbType.Int).Value = clientname;
            sqlinsertCmd8.ExecuteNonQuery();

Answer 1

您的插入语法错误

将此语法应用于所有语句

 SqlCommand sqlinsertCmd = new SqlCommand("INSERT TradeRecords(ClientID) 
 values(@clientID)";
sqlinsertCmd.Parameters.Add("@clientID", SqlDbType.Int).Value = clientID;
            sqlinsertCmd.ExecuteNonQuery();

无法将新数据插入数据库表，但代码的其他部分正在运行
