per MySQL direct komplette Datenbank lesen und speichern?

[Deltachaos]

Hallo kan ich per MySQL Direct die komplette Datenbank exportiren/denn inhalt igendwie Speichern?

Ich kann schon eine Verbindung aufbauen.

Hier mein Codeansatz:

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, IdBaseComponent, IdComponent, IdTCPConnection, IdTCPClient,
  IdFTP, StdCtrls, ComCtrls, inifiles, umysqlvio, uMysqlCT, uMysqlClient, uMysqlHelpers;

{$I mysqlinc.inc}

type
  TForm1 = class(TForm)
    IdFTP1: TIdFTP;
    TrackBar1: TTrackBar;
    Button1: TButton;
    Memo1: TMemo;
    hostname: TEdit;
    port: TEdit;
    username: TEdit;
    password: TEdit;
    Button2: TButton;
    Button3: TButton;
    mysqlhost: TEdit;
    mysqlport: TEdit;
    mysqlusername: TEdit;
    mysqlpassword: TEdit;
    mysqldatenbankname: TEdit;
    Label1: TLabel;
    Label2: TLabel;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
  private
    FMysql: TMysqlClient;
    FResult: TMysqlResult;
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

var log, sett: TIniFile;
    Present: TDateTime;
    Year, Month, Day, Hour, Min, Sec, MSec: Word;

Damitt sich die Buchstaben "von selbst tippen"

Delphi-Quellcode:

procedure dos(Eingabe: String; sleeper: integer);
var I:Integer;
const
  U = #13 + #10;
begin
  for I:=1 to Length(Eingabe) do
    begin
      form1.Memo1.Text:=form1.Memo1.Text+Eingabe[I];
      form1.Memo1.Refresh;
      Sleep(sleeper)
    end;
  form1.Memo1.Text:=form1.Memo1.Text + u;
end;

Kleine Spielerei, Fenster Transparent machen

Delphi-Quellcode:

procedure TForm1.Button1Click(Sender: TObject);
var trans: integer;
begin
  Present:= Now;
  DecodeDate(Present, Year, Month, Day);
  DecodeTime(Present, Hour, Min, Sec, MSec);
  trans:= form1.TrackBar1.Position * 2;
  trans:= trans div 5;
  log.WriteString(inttostr(day)+'.'+inttostr(month)+'.'+inttostr(Year), inttostr(hour) +':'+ inttostr(min) +':'+ inttostr(sec), '>>> Ändere Programmtransparentz auf: '+ inttostr(trans) + '%');
  alphablendvalue:=form1.TrackBar1.Position;
  Alphablend:=true;
end;

Verbindung zur MySQL Datenbank;

Delphi-Quellcode:

procedure vermysql;
begin
  Present:= Now;
  DecodeDate(Present, Year, Month, Day);
  DecodeTime(Present, Hour, Min, Sec, MSec);
  log.WriteString(inttostr(day)+'.'+inttostr(month)+'.'+inttostr(Year), inttostr(hour) +':'+ inttostr(min) +':'+ inttostr(sec), 'Setze MySQL-Port auf ' + form1.mysqlport.Text);
  dos('['+ inttostr(hour) +':'+ inttostr(min) +':'+ inttostr(sec) +'] Setze MySQL-Port auf ' + form1.mysqlport.Text, 60);

  form1.FMysql.Host := form1.mysqlhost.Text;
  form1.FMysql.port := strtoint(form1.mysqlport.text);

  Present:= Now;
  DecodeTime(Present, Hour, Min, Sec, MSec);
  log.WriteString(inttostr(day)+'.'+inttostr(month)+'.'+inttostr(Year), inttostr(hour) +':'+ inttostr(min) +':'+ inttostr(sec), 'Sende MySQL-Username ['+ form1.mysqlusername.Text +']');

  form1.FMysql.password := form1.mysqlpassword.Text;

  form1.FMysql.UnixSocket := '';

  form1.FMysql.UseNamedPipe := false;
  form1.FMysql.UseSSL := false;
  form1.FMysql.Compress := true;
  form1.FMysql.TrySockets := false;
  if form1.FMysql.Connect then
    begin
      Present:= Now;
      DecodeDate(Present, Year, Month, Day);
      DecodeTime(Present, Hour, Min, Sec, MSec);
      log.WriteString(inttostr(day)+'.'+inttostr(month)+'.'+inttostr(Year), inttostr(hour) +':'+ inttostr(min) +':'+ inttostr(sec), 'Verbindung zu MySQL-Datenbank erfolgreich!');
      dos('['+ inttostr(hour) +':'+ inttostr(min) +':'+ inttostr(sec) +'] Verbindung zu MySQL-Datenbank erfolgreich!', 60)
    end
  else
    begin

    end;
end;

Verbinde zum FTP-Server (Soll ja mal ein Hompagebackupprogramm werden)

Delphi-Quellcode:

procedure dlord;
begin

  try

Zum Conecten und speicher des Feld Inhaltes

Delphi-Quellcode:

procedure TForm1.Button2Click(Sender: TObject);
begin
  dlord;
  vermysql;
  
  sett.WriteString('FTP', 'Hostname', form1.hostname.Text);
  sett.WriteString('FTP', 'Port', form1.port.Text);

  sett.WriteString('MySQL', 'Username', form1.mysqlusername.Text);
  sett.WriteString('MySQL', 'Password', form1.mysqlpassword.Text);
  sett.WriteString('MySQL', 'Datenbankname', form1.mysqldatenbankname.Text);

  form1.Button2.Enabled:= false;
  form1.Button3.Enabled:= true;
end;

Zum Disconnecten

Delphi-Quellcode:

  form1.Button3.Enabled:= false;
  form1.Button2.Enabled:= true;
end;

Lesen der Voreinstellungen der settings.ini

Delphi-Quellcode:

procedure TForm1.FormCreate(Sender: TObject);
begin
  FMysql := TMysqlClient.create;
  sett:= TiniFile.Create(ExtractFilePath(ParamStr(0))+
                         'settings.ini');

  FMysql.Free;
  if FResult<>nil then
    FResult.free;

end.

Dass funktionirt ja auch so weit ich weis nur nicht weiter mit dem Backup!

Hallo Maximilian,

je nachdem, ob du eine Datenbank als Ganzes (mysqldump, mysqlhotcopy) oder alle Tabellen einzeln (LOCK TABLES; SELECT INTO OUTFILE) sichern möchtest, musst du anders vorgehen.

Lies dir dazu mal das Kapitel "Database Administration :: Backup and Recovery" in der MySQL Dokumentation durch.

Ich wies nich genau was einfacher ist.
Aufjedenfall sollte das Bakup wieder aufspielbar sein. entweder über das Programm oder über PHPmyAdmin

[Deltachaos]

Noch wer da?

[Deltachaos]

Ich denckemal alle tabellen eizeln da der MySQl Benutzer nicht die rechte hat eine neue Datenbank zu erstellen. sagt auf jedenfall PHPmyAdmin

Ich hab mir das etz mal durchgelesen.

Zitat:

Another technique for backing up a database is to use the mysqldump program or the mysqlhotcopy script. mysqldump is more general because it can back up all kinds of tables. mysqlhotcopy works only with some storage engines. (See Section 4.5.4, “mysqldump — A Database Backup Program”, and Section 4.6.8, “mysqlhotcopy — A Database Backup Program”.)

Create a full backup of your database:

shell> mysqldump --tab=/path/to/some/dir --opt db_name

Or:

shell> mysqlhotcopy db_name /path/to/some/dir

You can also create a binary backup simply by copying all table files (*.frm, *.MYD, and *.MYI files), as long as the server isn't updating anything. The mysqlhotcopy script uses this method. (But note that these methods do not work if your database contains InnoDB tables. InnoDB does not necessarily store table contents in database directories, and mysqlhotcopy works only for MyISAM and ISAM tables.)

For InnoDB tables, it is possible to perform an online backup that takes no locks on tables; see Section 4.5.4, “mysqldump — A Database Backup Program”.

meine Frage ist jetzt funktionirt das auch mit MySQL Direct oder besser: kann man mit MySQL direct wol jeden von der Datenbank unterstützen Befehl ausfüren?? wen ja wehre das Ja toll
