TSQLExporter tsqlexporter.png is a database export component for use with a TDataSet. It may be found on the Data Export tab of the Component Palette To export the contents of a TDataSet (for instance the result of a TSQLQuery correctly setup to link with a TSQLConnector and TSQLTransaction) also FormatSettings.TableName need be provided.

In the example below a a TSynEdit is filled with exported contents of table mytable.

type
  myForm = class(TForm)
    btnExport: TButton;
    myConnector: TSQLConnector;
    myExporter: TSQLExporter;
    myQuery: TSQLQuery;
    myTransaction: TSQLTransaction;
    myScriptText: TSynEdit;
    mySyntax: TSynSQLSyn;
    procedure btnExportClick(Sender: TObject);
  private
    procedure ExportTable( const tblnam: String );
  end;

implementation


procedure myForm.btnExportClick(Sender: TObject);
begin
  ExportTable( 'mytable' );
end;


procedure myForm.ExportTable( const tblnam: string );
var
  ts: TStringStream;
begin
  try
    ts := TStringStream.Create( '' );
    myTransaction.Database := myConnector;
    myQuery.Database := myConnector;
    myExporter.DataSet := myQuery;

    myQuery.SQL.Text := 'SELECT * FROM ' + tblnam;
    myQuery.Open();

    with myExporter.FormatSettings do begin
      TableName :=      tblnam;                 // exporter uses tablename in insert statements
      DateFormat :=     'YYYY-MM-DD';           // SQL date format
      DateTimeFormat := 'YYYY-MM-DD hh:mm:ss';  // 
    end;

    myExporter.ExportToStream( ts );
    myScriptText.Text := ts.DataString;  //show formatted script text

    myQuery.Close();
  finally
    ts.Free();
  end;
end;
