with Delphi i have tried, tru ODBC, you need to download ODBC driver for MySQL. then use standard ODBC components.

I could give you real working example after few days (i dont have delphi right now, but the example that worked i have left at my friend's home PC :))

maybe after some 12h.

hi,
you can use odbc as above but i prefer to use directly to mysql db using one of the mysql units/comps as sometimes end users may not have the odbc drivers installed etc..
this is one of the best component ones and works on all versions of windows.

http://productivity.org/projects/mysql/

also you can get the freeware source code for winmysql
(it was wrote in delphi using the units im mentioning above)it is a front-end / db-manager thing,one of the better ones for mysql,and with the source you can modify it to suit..
http://www.winmysql.com/page4.html

i also have a couple of demos of other mysql units etc if you want them let me know as i dont know where i got them though the above stuff should cover it all anyways.
Regards
Barry

For Delphi, I find native access to mySQL is much faster... http://www.zeoslib.org

It's free :)

OK. here would be my example.
It executes query, and prints space seperated values into the memo.
Needed lybraries: MyOLEDB, MyODBC, can be found at www.mysql.com

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, ADODB, Db;

type
  TForm1 = class(TForm)
    Button1: TButton;
    ADOConnection1: TADOConnection;
    Button2: TButton;
    Button3: TButton;
    Edit1: TEdit;
    Memo1: TMemo;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
begin
 ADOConnection1.ConnectionString:='DSN=UzeruDB';
// use 'ODBC Data Sources' in Control panel, to create a System DSN.'  
// you should set Driver('MySQL'), DSN Name (Used here), hostname ('localhost', or server IP), Database Name ('MYSQL').  
 Memo1.Align:=alBottom;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  ADOConnection1.Open; // only if you need to ask user for username/pass
end;

procedure TForm1.Button2Click(Sender: TObject);
var RecSet: _Recordset;
    S: string;
    i: integer;
    j: integer;
begin
  RecSet:=ADOConnection1.Execute(Edit1.Text);
  S:=' | ';
  for i:=0 to RecSet.Fields.Count-1 do begin
    S:=S+RecSet.Fields[i].Name+' | ';
  end;
  Memo1.Lines.Add(S);
  Memo1.Lines.Add(''); //empty line
  for j:=0 to RecSet.RecordCount-1 do begin
    S:=' | ';
    for i:=0 to RecSet.Fields.Count-1 do begin
      S:=S+RecSet.Fields[i].Value+' | ';
    end;
    Memo1.Lines.Add(S);
    Memo1.Lines.Add('');
    RecSet.MoveNext;
  end;
end;

procedure TForm1.Button3Click(Sender: TObject);
begin
  ADOConnection1.Close;
end;

end.
