  1. Allow Joined tables' columns to be updated in TDBGrid, as ADO allows

    When using TADOConnection / TADOQuery to create datasource for TDBGrid, columns from main tables as well as joined tables may be edited in the grid. With TUNIxxx components, only the first table in the query can have its columns updated in the grid.

  4. Install directories

    You guys use several uncommon directories for 3rd party components : 1: windows\System32 for some BPL
    2: Delphi\Lib for some dcp
    3: Delphi\Bin for some other BPL
    4: UniDAC for dcu

    How about using
    BDSCommon\BPL for all bpl
    BDSCommon\DCP for all dcp
    leaving the dcu in the lib of the unidac install directory

    To explain : As a developer i work with several virtual PCs that I have to update. I use a local SVN for that. Installing unidac is always a hassle because after the install I first have to copy everything where it's supposed to be and then…

  6. pack data between server(LINUX) and client(Windows)

    I would like to develop server program at LINUX(Lazarus) and client program at Windows(Delphi). I need to pack dataset on server site. I am using unidac with sql to access relational database. It is better to save returned dataset to memorystream quickly and transfer the stream to client. Also I want to restore memorystream to uniquery dataset quickly.

  8. creating native provider for advantage database

    The ODBC-provider for ADS has some restrictions, for example can't access encrypted free tables).
    Also FireDac has already an native provider for ADS.

  9. 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.

  10. 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…

  11. 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.

  13. Ability to localize TCRDBGrid

    CRDBGrid have only one popup where it shows "Filtered", "Filter Bar", "Search Bar" as a text and everything else is pictures on it. Or, field names which can be set by programmer.

    It would be nice to be able to localize these texts in the object inspector. Should be pretty easy to implement, and would be a nice addition to the component.
