Question

我的insert语句出现语法错误，但我找不到错误。

这是我的方法

String sql = "insert into receivers (receiver_id, receiver_name, salary, team,     forty_yard_dash, position, offense) " + 
                                "values" + 
                                "(@id, @name, @salary, @team, @forty, @position, @offense)";
        com = new OleDbCommand(sql, con);
        com.Parameters.AddWithValue("@id", rec.id);
        com.Parameters.AddWithValue("@name", rec.name);
        com.Parameters.AddWithValue("@salary", rec.salary);
        com.Parameters.AddWithValue("@team", rec.team);
        com.Parameters.AddWithValue("@forty", rec.fortyYardDash);
        com.Parameters.AddWithValue("@offense", rec.offenseDefense);
        con.Open();
        com.ExecuteNonQuery();
        con.Close();

我的数据库如下所示：
receiver_id号码姓名文本
工资号码团队文字
forty_yard_dash号码职位文本
进攻是/否

任何帮助将不胜感激！

King King已在评论中指出：

您需要添加position

的参数

String sql = "insert into receivers (receiver_id, receiver_name, salary, team, forty_yard_dash, position, offense) " + 
             "values" + 
             "(@id, @name, @salary, @team, @forty, @position, @offense)";
    com = new OleDbCommand(sql, con);
    com.Parameters.AddWithValue("@id", rec.id);
    com.Parameters.AddWithValue("@name", rec.name);
    com.Parameters.AddWithValue("@salary", rec.salary);
    com.Parameters.AddWithValue("@team", rec.team);
    com.Parameters.AddWithValue("@forty", rec.fortyYardDash);
    //new --> I am assuming the value for position comes from rec.position; change to correct source
    com.Parameters.AddWithValue("@position", rec.position); 
    com.Parameters.AddWithValue("@offense", rec.offenseDefense);
    con.Open();
    com.ExecuteNonQuery();
    con.Close();

如果你没有告诉我们任何其他错误，这应该可以解决问题;）

除了.Parameters.AddWithValue缺少position语句之外，另一个问题是position在Access SQL中是reserved word，必须用方括号括起来CommandText中。我刚刚尝试了以下内容，它对我有用：

using (var con = new OleDbConnection())
{
    con.ConnectionString = myConnectionString;
    con.Open();

    using (var com = new OleDbCommand())
    {
        int rec_id = 1;                         //
        string rec_name = "Bubba";              //
        int rec_salary = 2000000;               //
        string rec_team = "Springfield Atoms";  // test data
        int rec_fortyYardDash = 99;             //
        string rec_position = "linebacker";     //
        bool rec_offense = false;               //

        string sql =
                "INSERT INTO receivers (" +
                        "receiver_id, " +
                        "receiver_name, " +
                        "salary, " +
                        "team, " +
                        "forty_yard_dash, " +
                        "[position], " +
                        "offense " +
                    ") VALUES (?,?,?,?,?,?,?)";
        com.Connection = con;
        com.CommandText = sql;
        com.Parameters.AddWithValue("?", rec_id);
        com.Parameters.AddWithValue("?", rec_name);
        com.Parameters.AddWithValue("?", rec_salary);
        com.Parameters.AddWithValue("?", rec_team);
        com.Parameters.AddWithValue("?", rec_fortyYardDash);
        com.Parameters.AddWithValue("?", rec_position);
        com.Parameters.AddWithValue("?", rec_offense);
        com.ExecuteNonQuery();
    }
    con.Close();
}
