If you are talking about Windows, and you want to use libcurl from TNetHttpClient, and you are using RAD Studio 11 Update 2, and you have System.Net.HttpClient.*.pas source code. Then with a simple modification of System.Net.HttpClient.Linux.pas, you can use it on Windows. Is it what you want ?

Is on the Tools -> Options -> User Interface -> Form Designer -> Enable VCL Styles ? If yes, then try to turn it off. Does it help ?

Who is it - rubicon 4 ?

I saw this post in German Delphi-Praxis: https://www.delphipraxis.net/209869-firedac-moeglichkeit-die-abfrage-schneller-zu-machen-delphi.html So, anybody, who have account on both forums can answer there ... "Normally" constants vs parameters slowness is due to bad query execution plan when the parameters are in use. For example, Oracle (and not only) will stop to use indexes, when a parameter data type is not the same as a field one in a WHERE clause. This is because a type conversion is required, even if it looks "obvious". For example, a field is VARCHAR2 and a parameter is defined as ftWideString (eg, assigning it using Value / AsWideString instead of AsAnsiString). There are more examples ... From Oracle doc (https://docs.oracle.com/cd/B19306_01/server.102/b14211/ex_plan.htm#i3305): PS: As always, a Delphi version will be good to know ...

Did you read and fully follow to the comment at: <demos>\Object Pascal\Database\FireDAC\Samples\DBMS Specific\MSSQL\QueryNotify\Unit1.pas Most of these are SQL Server "limitations" / "requirements".

At moment ftTimeStampOffset is not supported by FireDAC

For Update: INT128 NUMERIC with precision 19..38 TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE (limited) DECFLOAT(16/34) native statement timeout More later, because all other will be "interface breaking changes". So, not for Update.

Delphi 11 Update 1 will support Firebird 4.

Why you dont want to change the REST.Client.pas unit ?
