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.
// setup connection with database
SQLConnector1.ConnectorType := 'MySQL 5.1';
SQLConnector1.HostName := 'MyServer';
SQLConnector1.DatabaseName := 'MyDBName';
SQLConnector1.UserName := 'MyName';
SQLConnector1.Password := 'MyPass';
// connect SQLConnector, SQLTransaction, DataSource, SQLQuery and DBGrid
SQLTransaction1.Database := SQLConnector1;
SQLQuery1.Transaction := SQLTransaction1;
DataSource1.DataSet := SQLQuery1;
DBGrid1.DataSource := DataSource1;
// setup Query
SQLQuery1.SQL := 'SELECT * FROM MyTable';
// setup query to get (at least) two fields MyTable
DBGrid1.Columns[0].Title.Caption := 'Name';
DBGrid1.Columns[0].FieldName := 'fieldDescription';
DBGrid1.Columns[0].Title.Caption := 'Description';
DBGrid1.Columns[0].FieldName := 'fieldName';
// Open result and show in grid
SQLQuery1.Open();
