  1. Add refreshquick to PgDAC

    The RefreshQuick method (https://www.devart.com/mydac/docs/devart.mydac.tcustommydataset.refreshquick(system.boolean).htm) seems very useful to refresh only the new records from big datasets. Ideally, make it possible to specify the name of the TIMESTAMP field so we don't have to create a duplicate - mine are called "created" for example). Maybe we don't even need the TimeStamp field for Postgresql ?

  2. SqlMonitor : No "...monitoring is started/finished" event

    When I create a SqlMonitor but with Active := False the component or unit is sending a string to the monitor to say, that it has started, although it's inactive.
    Now imagine that with some 50 or 100 clients and you want to check the SQL of 1 certain workstation.

    Couldn't that be turned off ?

  3. sql monitor: support query execution

    It would be helpful in the SQL Monitor to execute the query I'm seeing to see the result set my app receives.
    Sometimes I have to check something where the client is and I place the sql monitor to see, what SQL my app is sending and have to enter with a db explorer to check the sql with the parameters sent, what the result is. It would be cool, if the dbmon could have that built in, because the dbmon already has the sql and the params right there.

    This would often make my work much easier

  4. Implement ServerMode to Unidac

    hi,
    Devexpress servermode nearly 10 times faster than unidac native components.
    Is there any chance you can also implement servermode into unidac?
    thank you

  5. 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.

  6. 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.

  7. 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.

  8. 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…

  9. Add Support For SQL Server "Always Encrypted"

    SQL Server now has a new security feature called "Always Encrypted". This is a recognised Microsoft solution for encrypting certain sensitive database columns to meet European Union GDPR regulations. Please add "Always Encrypted" support into Devart SQL Server data access components. This is a recognised approved solution to SQL Server DBA's.

  10. 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. Add desing time support for custom SQLite functions with UniDAC.

    When you add a new sql function at runtime (TLiteUtils.RegisterFunction) you can't use it at design time in a UniQuery because the function is unknown.

  16. dbMonitor needs an upgrade, adding some basic common sense functionality

    It's about time dbMonitor had a long awaited upgrade with some really basic common sense pieces of functionality added.

    1) Add buttons to clear terminated processes and all processes. Come on guys, having to select each process one by one to clear it is, quite frankly, ridiculous and poor UI design.

    2) Parameters should be formatted according to the DB you're connected to.
    E.g. for Oracle
    Like this...
    :SrcSchema VARCHAR2(13) :='MY_SCHEMA' ;

    rather than this

    :SrcSchema(VARCHAR[13])='MY_SCHEMA'
    Why? Well it allows us developers to set up anonymous blocks quickly to test the same call, if say an error occurs. Currently I…

  18. Add DBMonitor support for notifications

    For debugging purposes we often add
    raise notice '%', some_variable
    which is handy because can give us back information without stopping the app like 'warning' or 'exception' would.

    It would be great if DBmonitor could catch such notice and show somehow.

  19. Debug info shown in DBMonitor

    Unlike other product such as ODAC, for virtualDAC, as now I am using VirutalQuery, if debug is set to true, it seems that dialog will be shown at each step, which make the debug in thread/service very difficult.

    Is it possible, like TOraMonitor of ODAC, we have have sort of TVirtualDACMonitor for VirtualDAC, to push the debug information to dbmonitor, the same behavior as of other product family?
