TDBGrid

│ English (en) │ français (fr) │ 日本語 (ja) │ русский (ru) │

TDBGrid is a visual component that displays tabular data from database contents through means of a TDataSet derivative like a TSQLQuery. The TDBGrid component is available from the Data Controls tab of the Component Palette.

    // configure connection with database
  SQLConnector1.ConnectorType := 'MySQL 5.1';
  SQLConnector1.HostName := 'MyServer';
  SQLConnector1.DatabaseName := 'MyDBName';
  SQLConnector1.UserName := 'MyName';
  SQLConnector1.Password := 'MyPass';
  SQLConnector1.connected := true;
    // connect SQLConnector, SQLTransaction, DataSource, SQLQuery and DBGrid
  SQLTransaction1.Database := SQLConnector1;
  SQLQuery1.Transaction := SQLTransaction1;
  DataSource1.DataSet := SQLQuery1;
  DBGrid1.DataSource := DataSource1;
    // setup query to get (at least) two fields from MyTable
  SQLQuery1.SQL.Text := 'SELECT * FROM MyTable';
    // setup grid with result from query
  DBGrid1.Columns[0].Title.Caption := 'Name';
  DBGrid1.Columns[0].FieldName := 'fieldDescription';
  DBGrid1.Columns[1].Title.Caption := 'Description';
  DBGrid1.Columns[1].FieldName := 'fieldName';
    // Open result and show in grid
    // this will NOT WORK - at least with SQLite: circular datasource references are not allowed
  SQLQuery1.Open();
