  Hi all

  can anybody help me to solve my problem : writing in .dbf  , as following is my code with this error :

  [ ERROR [07002] [Microsoft][ODBC dBase Driver] Too few parameters. Expected 3 ]

   

  SqlConnection cn = new SqlConnection("Data Source=(local);Initial Catalog=test;Integrated Security=True");
          SqlDataAdapter da = new SqlDataAdapter("select * from test", cn);
          DataSet ds = new DataSet();
          da.Fill(ds, "test");
        
          string odbccon = "Dsn=TEST.DBF;dbq=E:\\FOX;defaultdir=E:\\FOX;driverid=533;fil=dBase 5.0;maxbuffersize=2048;pagetimeout=5";

          OdbcConnection connection = new OdbcConnection(odbccon);
          connection.Open();
          OdbcCommand createCommand = connection.CreateCommand();
        

       
          createCommand.CommandText = "CREATE TABLE test (ID int, name varchar(50),last_name varchar(50))";
          createCommand.ExecuteNonQuery();

          OdbcCommand insertCommand = connection.CreateCommand();
        
          insertCommand.CommandText = "INSERT INTO test (ID,name,last_name) VALUES (@pID,@pname,@plast_name)";
         
          foreach (DataRow dr in ds.Tables["test"].Rows)
          {
              int id = int.Parse(dr["ID"].ToString());
              string name = dr["name"].ToString();
              string last_name = dr["last_name"].ToString();
              insertCommand.Parameters.Add(new OdbcParameter("@pID", id));
              insertCommand.Parameters.Add(new OdbcParameter("@pname",name));
              insertCommand.Parameters.Add(new OdbcParameter("@plast_name",last_name));

  if you have more than a single

  DataRow dr in ds.Tables["test"].Rows

  then you add (3* number of dr ) parameters.

  Call

  insertCommand.Parameters.Clear()

  after

  insertCommand.ExecuteNonQuery();
