  3. Support for OpenSSL 1.1

    UniDAC currently only supports OpenSSL 1.0.2. This version won't be supported past 2019-Dec-31.

    To avoid problems UniDAC should support OpenSSL 1.1

  4. 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.

  11. 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…

  12. 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.

  13. Fix TMyDump

    TMyDump.Backup() writes all Views in alphabetical order. However, if there are inter-joins among Views the database may not be restored, as the Views must be restored according to their dependencies.

    I strongly suggest fixing TMyDump.Backup. The algorithm should analyze the dependencies among Views and account for the correct order of joins.

  18. New MasterConnection that uses master and slave connections

    A new component (MasterConnection) that uses master connection for read and write changes to DB , while uses slave connections to write and update only for online backup and fail safe recovery point.
    use case:
    An application can use local SQLite server for all operation (read and write) due the performance performance advantage ,while a remote MySQL server along with a Cloud SQL provider receive all and only all (write operations -insert/update/delete)

  20. New component "Dump"

    It would be great to have the existing component "TDADump" in UniDac for IBDac
    but with more functionality that would be "Update or Insert"
    this component could do export and import SQL data from one table to another table.
