使用C＃VS2008插入MS Access 2007 ODBC

Question

我需要一些幫助，在VS2008中使用C＃爲Access 2007數據庫創建插入語句。當前的代碼給了我「INSERT INTO語句中的錯誤42000：語法錯誤。」我不知道什麼是錯的。我基於今年早些時候使用的一個工作代碼編寫了這段代碼，該代碼連接到一個ms訪問表並將數據庫信息傳輸到一個oracle數據庫中。

當前代碼

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Diagnostics; 
using System.Linq; 
using System.Text; 
using System.Data.OracleClient; 
using System.Data.SqlClient; 
using System.IO; 
using System.Data.Odbc; 
class MainClass 
{ 
static void Main(string[] args) 
{ 
    string connectionString = "Dsn=Northwind 2007"; 
    string SQL = "SELECT * FROM Orders"; 
    string sqlins = ""; 
    OdbcConnection conn = new OdbcConnection(connectionString); 

    OdbcCommand cmd = new OdbcCommand(SQL); 
    cmd.Connection = conn; 
    OdbcCommand cmdnon=new OdbcCommand(sqlins,conn); 
    try 
     { 

     conn.Open(); 

     OdbcDataReader reader = cmd.ExecuteReader(); 
     while (reader.Read()) 
     { 
      Console.Write("OrderID:" + reader.GetInt32(0).ToString()); 
      Console.Write(" ,"); 
      Console.WriteLine("Customer:" + reader.GetString(1).ToString()); 
      cmdnon.CommandText = "INSERT Commonstation (S1Flow,S2Flow,S3Flow,S4Flow) VALUES (9999,999,999,999)"; 
      int rowsAffected = cmdnon.ExecuteNonQuery(); 
      Console.WriteLine(rowsAffected); 
     } 
    } 
    catch (Exception ex) 
    { 
     Console.WriteLine(ex.InnerException.ToString()); 
    } 
    finally 
    { 
     reader.Close(); 
     conn.Close(); 
    } 
} 
}

Answer 1

嘗試：

cmdnon.CommandText = "INSERT INTO Commonstation... 

至少，那是什麼錯誤是告訴你。

Answer 2

string MyAccessConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:/mydata.accdb;Persist Security Info=False;"; 

private void button1_Click(object sender, EventArgs e) 
{ 
    OleDbConnection conn = new OleDbConnection(MyAccessConn); 
    OleDbCommand cmd; 
    conn.Open(); 
    try 
    { 
     cmd = conn.CreateCommand(); 

     cmd.CommandText = "INSERT INTO data([Name],[Surname],[Username],[Password]) VALUES(@Name,@Surname,@Username,@Password)"; 
     cmd.Parameters.AddWithValue("@Name", name_txt.Text); 
     cmd.Parameters.AddWithValue("@Surname", sur_txt.Text); 
     cmd.Parameters.AddWithValue("@Username", user_txt.Text); 
     cmd.Parameters.AddWithValue("@Password", pwd_txt.Text); 

     cmd.ExecuteNonQuery(); 
    } 
    catch (OleDbException ex) 
    { 
     MessageBox.Show(ex.Message); 
    } 
    finally 
    { 
     if (conn.State == ConnectionState.Open) 
     { 
      conn.Close(); 
     } 
    } 
}
