本文介绍了一个使用Delphi编写的程序，该程序通过InterBase数据库组件实现表格数据的操作，包括打开表格及获取表格索引信息的功能。

unit UIB_Table;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, DB, IBCustomDataSet, IBTable, IBQuery, DBTables, StdCtrls,
  Grids, DBGrids, ExtCtrls, DBCtrls, IBDatabase, CheckLst;

type
  TFIB_Table = class(TForm)
    IBTable1: TIBTable;
    Button1: TButton;
    DBGrid1: TDBGrid;
    DataSource1: TDataSource;
    IBDatabase1: TIBDatabase;
    IBTable2: TIBTable;
    DataSource2: TDataSource;
    DBGrid2: TDBGrid;

    Label1: TLabel;
    Label2: TLabel;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  FIB_Table: TFIB_Table;

implementation

{$R *.dfm}

procedure TFIB_Table.FormCreate(Sender: TObject);
begin
 IBTable1.Open;

end;


//获取IBTable1组件的索引，并将索引字段名称显示在编辑框中
procedure TFIB_Table.Button1Click(Sender: TObject);
var
 I:Integer;
begin
    IBTable1.Active := False;
    Memo1.Text :='';
    IBTable1.IndexDefs.Update;
    //获取IBTable1组件的索引
    for I := 0 to IBTable1.IndexDefs.Count - 1 do
    begin
      //将索引字段名称显示在编辑框中
        memo1.Lines.Add(IBTable1.IndexDefs[I].Fields)   ;
       end;
    IBTable1.Active := True;
end;

end.
