Lars, to answer your question - no.

Did you consider just using SQLite?

If you can, purchase this: http://www.jensendatasystems.com/firedacbook/

I see this is an old question 😉 Anyway, I should have asked: Is there a particular reason you are using Firebird?

Why are you using Firebird?

Refresh meaning you call TFDQuery.Refresh?

Take a look at this line in the link Lars posted: CREATE INDEX / DROP INDEX. Instead of the SQL indexes, use the dataset indexes. Seems to me that means if the TFDMemTable has indexes they will be used.

Gross margin as a percentage: Gross Margin % = (Revenue – Cost of Goods Sold) / Revenue * 100 (Sell - Cost) / Sell * 100

You should take some time and read this topic: Configuring Drivers (FireDAC) - RAD Studio (embarcadero.com)

Create a new project and go through the pain of adding your source files to it. Not ideal, but you'll be happy for taking the time to do it.

Code completion works great in 10.4.2 - with Clang compiler projects.

I have no comment on the debugger parts of the question.

It's VERY fast - when using a Clang compiler.

Is this error produced from a new VCL application project? What version are you using?

I actually moved some software from the Classic compiler over to the 32-bit Clang compiler using 10.4.2! The project uses DevExpress, JEDI, AsyncPro, OnGuard, and Indy components.

Did you search your code for #pragma link "Data"?

FYI, this issue remains unresolved in 10.4.2. I added some more details to the report today.

DevExpress has published their potential road map for 2019 with an important question: do you need a FireMonkey Grid in 2019? https://community.devexpress.com/blogs/vcl/archive/2019/01/28/vcl-controls-2019-roadmap-your-vote-counts.aspx

That blog post has 156 comments so far so good job making your preferences known. The only VCL blog post that is even close to having that many comments is from back in 2011 when they changed to the subscription model and that only had 90 comments!

I suppose you mean 18.1.3. So which components do you use? I don't see the issue that you are describing. I'm using the Grid, Inspector, Bar Manager, Skin Controller, Printing, part of Scheduler. I'm using 18.1.6 with C++Builder Seattle 10 (No Update) and Tokyo 10.2.3.

What DevExpress components are you actually using with your project?
