Delphi X10.2 + FireDAC 使用 SQL 语句 UPDATE

MainForm.Conn.StartTransaction;
UserManagerQuery.SQL.Clear;
UserManagerQuery.SQL.Text := ‘UPDATE tabusers SET ‘ + //
          ‘username=:username, userpwd=:userpwd, usernickname=:usernickname, ‘ +
          ‘useroffice=:useroffice, userprofiles=:userprofiles, ‘ +
          ‘userpermission=:userpermission, useronline=:useronline ‘ + ‘WHERE ID=‘
          + edtID.Text;

          UserManagerQuery.Params[0].AsString := edtUserName.Text;// name

        if Using_Default_Pwd then
          UserManagerQuery.Params[1].AsString := Default_Password
        else
          UserManagerQuery.Params[1].AsString :=
            MD5Print(MD5StringA(AnsiString(edtUserPwd.Text))); // password

        UserManagerQuery.Params[2].AsString := edtUserNickName.Text; // nickname
        UserManagerQuery.Params[3].AsString := edtUserOffice.Text; // office

        MS := TMemoryStream.Create;
        ImgUserProfiles.Picture.SaveToStream(MS);
        MS.Position := 0;
        UserManagerQuery.Params[4].LoadFromStream(MS, ftBlob); // profile
        MS.Free;

        UserManagerQuery.Params[5].AsString   := edtUserPermission.Text; //permission
        UserManagerQuery.Params[6].AsBoolean  := False; //online

        UserManagerQuery.ExecSQL;
        MainForm.Conn.Commit;

　　真TMD的爽，快抛弃 EDIT/POST 这么落后的玩意吧。
