  2. Add "Inverse Null Sort" (f.e.: "IN") function to IndexFieldNames

    As the "coInvertNullOrder" flag -for client side sorting the dataset- is already imlpemented for some of the providers, it would be nice to be able to control the default method how NULL values are sorted (comes as first or comes as last).

    The best approach would be to be able to control this over f.e. with an "IN" postfix in the IndexFieldNames, per field.

    Like: "SomeField DESC IN;OtherField ASC"

    Thx.

  9. Add delta support like Firedac for cachedupdates, better yet as a Tunidatasetoption

    Your implemantation of cached updates with Updatebatchsize is super fast in comparison to firedac. But sometimes we need to see query delta to apply changes to other datasets without using stored procedures.

  14. Автозагрузка свойств поля TField

    У компонентов FIBPlus есть замечательная фича.
    Когда в базе (Firebird) меняешь размер поля, то не нужно корректировать этот размер у DataSet компоненты. Компонента (TpFibDataSet) сама подтянет новый размер поля в дизайнтайме.
    Было бы здорово, чтобы компонента TUniQuery тоже такое умела.
    Вообще, желательно, чтобы подгружался не только размер поля, а и другие параметры и не только текстового.
    Я работаю с UniDAC примерно с 2012 г и удивлён, что этой фичи ещё нет.
    У FIBPlus много вкусного, жаль, что они больше не развиваются.

    Под словом "подтягивать" я имел ввиду брать из базы, из системных таблиц читать разные параметры поля и применять их…

  15. Автогенерация InsertSQL, UpdateSQL

    Я знаю, что у TUniQuery есть возможность сгенерировать доп. запрос на основе SelectSQL.
    Но это неочевидно, в справке нет. Нет готовых методов.
    Приходится открывать предварительно сам запрос, что есть не совсем правильно.

    [code] UniQuery1.Open;
    UniQuery1.SQLUpdate.Text := TDBAccessUtils.SQLGenerator(UniQuery1).GenerateSQL(TDAParamsInfo.Create(TDAParamInfo) , _stUpdate, true);
    UniQuery1.SQLRefresh.Text := TDBAccessUtils.SQLGenerator(UniQuery1).GenerateSQL(TDAParamsInfo.Create(TDAParamInfo) , _stRefresh, true);
    [/code]
    да и без UniQuery1.Open вываливается AV :(

    Было бы здорово, если бы было что-то вроде:
    UniQuery1.GelerateAllSQLs.
    UniQuery1.GelerateInsertSQL;
    UniQuery1.GelerateUpdateSQL;
    UniQuery1.GelerateDeleteSQL;
    и т.д.
    и без обязательного открытия набора данных.

  18. Cloned Cursors

    Today i'm more and more using TClientDataset because of the cloned cursor and Unidac just for for synchronize and transport between the back end database and the TClientDataset. With a cloned cursor multiple components can share the same data-space and the speed and memory gains are huge, but i would preferer to do this in the unidac and not have another extra layer of technology.

    A tQuery with all the functionality of tClientDataSet would be very nice and Firedac is moving that way.
