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 you1 vote -

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

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 ?

Threadsafe TUniAlerter for multithreaded applications
TUniAlerter.OnEvent is always called in the main application thread regardless in what thread TUniAlerters is created or used.
Devart advice is to use a synchronize, but that is not always possible or wanted. Why or you otherwise using threads?3 votes -
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 ?

Make CachedUpdates work on master-detail datasets without requiring LocalMasterDetail
Scenario: 100K customer (master rows) with an average of 10 contact (detail) rows each... totaling about 1M detail rows.
Without CachedUpdates I set LocalMasterDetail to false, and each time I scroll on the master dataset UniDAC fetches the 10 or so detail rows from the database. I can insert, modify and delete rows and all is saved immediately (on Delete or Post).
With CachedUpdates I have to set LocalMasterDetail to true. This means UniDAC will fetch 1M detail rows and filter them out locally. With large networked databases this is really not feasible as it generates too much network traffic…

Green tick mark for answered queries?
Perhaps it's an idea to have an indicator on each specific post to show whether a topic has been answered?
This could be as simple as a check box indicating the post has been answered - filled in by the original requester when the requester is happy with the response(s).
Once the tick box is completed the post could be flagged with an icon - e.g. a green tick mark - and thus considered 'closed'.
Would help responders to skip those posts already answered and those wishing to find answers to skip those posts that have not yet been answered.…1 vote -

Do not create duplicate parameters when a parametername is used multiple times in a query text
When you have a query like
select *
from mytable
where COALESCE(DVALIDFROM, :PeriodTo) <= :PeriodToThen the params property of a TMSQuery component now contains the parameter 'PeriodTo' twice. This behaviour differs from the behaviour of TUniQuery. I think the behaviour of TMSQuery needs to be changed such that is has the behaviour of TUniQuery.

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.

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.

Allow to connect with another Windows User
When TMSConnection.Authentication is auWindows the username is the currently logged in user, it woudl be good to have a way to connect as another user. There could be a new property TMSConnection.ImpersonateUser, if this is set and auWindows is set the connection will be done as if that user is logged in.

dbMonitor -- update/insert/delete statements should be reflected in UpdateTransaction
if you apply two different transaction in TIBCQuery.Transaction and TIBCQuery.UpdateTransaction property, then dbMonitor will show update/insert/delete statements in TIBCQuery.Transaction branch.
Actually it should be shown in TIBCQuery.UpdateTransaction branch
RUS
Если вы применяете две различных транзакции в свойствах TBCQuery.Transaction и TIBCQuery.UpdateTransaction то dbMonitor показывает выражения update/insert/delete в ветке транзакции TBCQuery.Transaction.
Однако хотелось бы видеть в ветке TIBCQuery.UpdateTransaction3 votes -

After append event
When working with DevExpress VCL Tools the Append and Insert are different, and no im forced to use Insert instead of Append in the CX grid because the append have no corresponding event in Unidac, i cant catch it. The insert and append behaves different in the CX grid.
