Question

我正在尝试运行控制台应用程序（连接并读取SQL），但在'。'附近收到错误语法错误。

        static void Main(string[] args)
    {
        string connstring = @"Data Source=Jama-Dharma\SQLEXPRESS;Initial Catalog=Cars;Integrated Security=True";
        SqlConnection conn = new SqlConnection(connstring);

        using (conn)
        {
            string query = "SELECT c.Name, c.Model c.Year FROM CarsCatalog c";
            SqlCommand command = new SqlCommand(query, conn);

            conn.Open();
            SqlDataReader reader = command.ExecuteReader();
            while (reader.Read())
            {
                Console.WriteLine(string.Format("{0} {1} {2}", reader.GetString(0), reader.GetString(1), reader.GetInt32(2)));
            }
            conn.Close();

        }
    }

Answer 1

将c.Model c.Year更改为c.Model, c.Year

Answer 2

你在这里错过了一个逗号：

string query = "SELECT c.Name, c.Model, c.Year FROM CarsCatalog c";

（在c.Model之后）

“。”附近的语法不正确
