C# : Microsoft Access 데이터베이스에 데이터를 삽입 할 수 없습니다.

Question

Microsoft Access 데이터베이스에 데이터를 삽입 할 수 없습니다. 여기 아래에있는 내 코드입니다 :

  roomTableAdapter.Connection.Open(); 
      string s = "INSERT INTO `room` ([number], [priceroom]) VALUES (@param1,@param2)"; 
      System.Data.OleDb.OleDbCommand cmd = new System.Data.OleDb.OleDbCommand(s, roomTableAdapter.Connection); 
      cmd.Parameters.AddWithValue("@param1", textBoxX4.Text); 
      cmd.Parameters.AddWithValue("@param2", "4000"); 
      roomTableAdapter.Adapter.InsertCommand = cmd; 
      roomTableAdapter.Adapter.InsertCommand.ExecuteNonQuery(); 

      roomTableAdapter.Adapter.Fill(this.database3DataSet5); 
      roomTableAdapter.Update(database3DataSet5.room); 



      dataGridViewX1.Update(); 
      dataGridViewX1.Refresh(); 
      roomTableAdapter.Connection.Close(); 

Answer 1

roomTableAdapter.Connection.Open(); 
string s = string.Format("INSERT INTO `room` ([number], [priceroom]) VALUES (@param1,@param2);"); 
System.Data.OleDb.OleDbCommand cmd = new System.Data.OleDb.OleDbCommand(s, roomTableAdapter.Connection); 
cmd.Parameters.AddWithValue("@param1", textBoxX4.Text); 
cmd.Parameters.AddWithValue("@param2", "4000"); 

roomTableAdapter.Adapter.InsertCommand = cmd; 
roomTableAdapter.Adapter.InsertCommand.ExecuteNonQuery(); 
roomTableAdapter.Adapter.Fill(this.database3DataSet5); 
roomTableAdapter.Update(database3DataSet5.room); 

dataGridViewX1.Update(); 
dataGridViewX1.Refresh(); 
roomTableAdapter.Connection.Close(); 

Answer 2

액세스 SQL에는 "틱"이 없어야합니다. 따라서 :

string s = string.Format("INSERT INTO room ([number], [priceroom]) VALUES (?,?);");
