推荐答案

您可以使用我的 SQLite包装器（以及我的博客中的一些更多信息），它支持多个平台。在Windows中，您需要在应用程序中部署sqlite3.dll，在OSX上不需要这样做。您可以从svn获取源。用法示例：

You can use my SQLite wrapper (also some more info in my blog) which supports multiple platforms. In Windows you'll need to deploy sqlite3.dll with your application, there is no need for this on OSX. You can get sources from the svn. Example usage:

uses
  SQLiteTable3,
  {$IFDEF DELPHI16_UP}
  System.SysUtils;
  {$ELSE}
  SysUtils;
  {$ENDIF}

procedure Demo;
var
  slDBpath: string;
  db: TSQLiteDatabase;
  pstm TSQLitePreparedStatement;
begin
  slDBpath := IncludeTrailingPathDelimiter(GetHomePath) + 'test.db';
  db := TSQLiteDatabase.Create(slDBpath);
  try
    if db.TableExists('testtable') then
    begin
      pstm := TSQLitePreparedStatement.Create(db,
        'insert into testtable (name,number) values (?,?)',  //sql statement
        ['NewRec', 99.99]); //parameter values
      try
        pstm.ExecSQL;
      finally
        pstm.Free;
      end;
    end;

  finally
    db.Free;
  end;
end;
