Interbase XE7 performance issue
Hello!
Currently our company have some Interbase XE database servers. This summer we needed to create another database server. Unfortunatelly, Embarcadero ddn't provide Interbase XE licence, only Interbase XE7. When we bought and installed this version, we've faced huge performance troubles with our buisness operations.
After lot of researches, we found that query plans on same SQL queries are different on XE and XE7. For some reason XE7 tried to use two indices when XE used one.
For example,
*** SM INDEX (TBL_STORES_AND_MOVES_STORE_ST,TBL_STORES_AND_MOVES_CAT_ST) *** - XE7
*** SM INDEX (TBL_STORES_AND_MOVES_CAT_ST) *** - XE
Because of this issue, some queries on Interbase XE7 works 10-20 times longer then on Interbase XE, and this is impossible for us.
May we have some licence downgrade from Interbase XE7 to Interbase XE?

FireDac for FireBird
Hi all,
I'm new here. In fact, I used to be a .NET developer for to many years, and now I should get into Delphi and FireBird.
In order to achieve this, I download the RAD Studio 10.2.1 trial version and installed it on my home machine. The trial period should be enough to learn the basics and figure out how the things are running in Delphi, the syntax and, of course, how to connect and manipulate data in a database. In this case, the company is using FireBird.
After the installation, I found that a bunch of nice application samples were also installed. Nice indeed. I tried to run them all, but some of them couldn't be started, due some missing libraries.
After some thought exchange with my colleagues, I got the reason why: it lacks the FireDac for FireBird. Ok. So... uninstall everything and reinstall... something went wrong in the first time. Some problem.
Therefore, I realize that the FireDac isn't part of the trial version. As the rest of the company is using it a lot, it is supposed that I learn the maximum possible on every platform they are using, and that includes FireDac.
So... I'm asking... It is real that the firedac doesn't come with the trial version of the RAD Studio? Is there any way for me to install it for a kind of a trial period so I could learn the maximum about it?
Many thanks in advance for all the time spent and information that you can send me.
All the best,
Artur

Regarding Case# 00594888: Bcd Field Overflow runtime error with floating points data from Quickbooks
First: I have an commission program built with Dephi Enterprise Berlin on win32 platform. Database is Quickbooks Version Enterprise 2017 desktop pro has its own driver for odbc for read access called QODBC that is shipped and installed with Quickbooks. So, I am using FDConnection components and they have been working fine until I upgraded to Delphi 10.2 and recompiled the program. This created an BCD overflow runtime error with all BCD fields mapped from Quickbooks.
Next: I found that changing Delphi Firedac component fdconnection to ADOconnection and I did not get the BCD error, (worked fine). Also, I continued with Firedac component FDConnection using FDQuery and was able to use the FDQuey Data Mapping rules to change dtBCD to dtDouble and that also fixed the problem.
However, this means that I will have to make this change and retest everything, not cool.
Also, when I went to Studio 10.2 Tokyo the Firedac components that are working with Firedac ODBC conponent isn't working correctly for BCD fields.
Delphi maps these fields as BCDField (Precision 13 size 2) from Quickbooks database.
Trace file and after the trace below is a grid shot showing the data with the Bcd overflow results.
However, I did notices that values in the bcd field that have a Decimal value had the overflow error and whole numbers did not.
Trace:
--- new start of FireDAC Trace ---

My sqllite database responds with "DATABASE IS LOCKED". How are we supposed to update a record please?
I have a multi-device app with a FDconnection, Bindsource and 2 queries used to populate 2 listviews.
These use a very simple sqllite database with 3 tables in it.
I need to be able to edit records in one of those tables and then re-display icons on one of the listviews (by clicking colorbuttons).
I have tried setting Lockingmode=Normal in the FDconnection (in code on the beforeconnect event - as if you try to change that setting in the editor Delphi comes up with loads of field not found messages that then prevent you closing your project AND YOU LOSE ALL RECENT CHANGES).
I have tried closing the FDconnection, re-opening it and then running an "update table set field=nn" query. It falls over on the execSQL saying that the database is locked.
I have also tried using the same table query to do a
locate
append
Edit
fieldbyname('fieldname').asinteger:=tag;
Post

Same locked database error
Please could somebody help - as this ought to be easy. All I want to do is update data for goodness sake. All very easy in VCL.
This is for single user access on a single database on a mobile phone (whilst displaying the same data in 2 listviews).

ListView item anchored?
Hi,
Is there a way to have the ListView item positions adjust depending on the form size, or portrait/landscape presentation?
I have a ListView with all my items set correctly using the "Toggle Design Mode" option. But how to tell each item to stick to the right or left of the list when the view width increases?
I have columns with totals, but they remain in the same position when flipping to landscape mode on mobile devices?
In Portrait they're on the right of the screen, in Landscape, they stay in the middle of the screen instead of moving to the right.
Thanks for any clue.

Update subitems from TListView
Hi,
I made a form with a TListView and a ClientDataSet connected by LiveBindings. I would like to update the SubItems from TListViewItem with no cursor change. It's the same behavior of Twitter.
When I use the ClientDataSet.Locate method to select and to update the values, the TListView change the selected Item. Those values will change constantly, so I need to update those values with no cursor change.
Which is the best way to do this?

TButton images missing in Delphi 10S VCL app
Complex one here.
I have a large button image TImageList repository on a common form with 226 24x24 bmp images. I use these images to source imagery for all toolbars and TButtons in a rather large application. Some TButtons in forms are fed via TActionList items while others link directly to the TImageList object on the common form.
In my main application, all ToolBar buttons have their images. All form buttons have none when executing despite displaying perfectly in the form designer. Not just a blank image, but no image at all, with the Caption text centred in the button and no space for an icon.
However, in a test program in the same project group, linked to the same common form and using the same image repository, all TButton instances show their images as expected.
I have started debugging the VCL library code that paints the buttons in the main application (well - fails to...) and seen that a handle for the TImageList component is nil in the main application, but valid in the test program.
To add to the complexity, this is a 'suddenly' situation since these images used to show just fine in all circumstances.
Anybody have any suggestions how I can fix this?
