If your M$ SQL Server is NOT running at 80-90% memory it is not configured correctly, that's what it is suppose to do. A maintenance plan is a must for any SQL Server database, rebuilding indexes for performance over time needs to be done for performance in general. It takes our production system a little over a minute to backup a 6-7GB database during the day, the reason it only takes 20-30 minutes after you force the clients to exit is all the IO to the database stops, you could be fighting IO through-put and the SQL trying to get a good 'snap-shot' of the database. Our production system is a small 16GB VMware VM running on a host with 14 other VM's all connected to a SAN running SSD's. (could I put more acronyms in there?) Is this a 24/7 system? They are making regular SQL backups right? You could just restore after that, if not there are bigger problems. (This could/should be a backup script job in SQL) Is this a physical server or a VM (Hyper-V/VMware/Proxmox)? They are not running some anti-virus that is looking at the database and/or backup folders are they? (anti-virus on the server is fine as long as the DB/backup folders are excluded, some cheaper A/V solutions are not smart enough to know not to to this) Does the database have lots of BLOB fields? If so are they on their own database partition(s)? (more of a performance issue if not) Never tried it but you may want to look into SQL Log Shipping instead of doing full backup/restore. It should be able to be configured to run on the same server with different database names.

RPG has advanced beyond columns a long time ago with RPG Free. I also started with RPG and COBOL on an IBM 4331, System/38 and AS/400 from the late 80's through early 2000's, good memories. Even used Delphi/400 back when it first came out and I was learning Delphi.

Ordered the paperback from Amazon to go with the other 3 on my bookshelf, after I read it of course.

If your daily machine, PC or MAC has 16GB of RAM, is a multi-core CPU and has 100-150GB of free space go with a virtual machine. There are free options like Hyper-V and VirtualBox even VMwares Workstation/Fusion is free for personal use. Delphi will run in a VM with 4-6GB of RAM and a 2 cores, not speedy but it will run. You can get a real copy of Windows 10/11 for cheap online and it's easy to backup with just a file copy.

Use the TFDConnection object's GetInfoReport() method, it takes a string list. It shows everything you want to know about the connection and the driver it used/picked. We have this on our login/splash screen hidden behind a TLabel double-click event because we were having the same types of issues. Also look into the FDDrivers.ini file configuration. ================================ Connection definition parameters ================================ DriverID=MSSQL Database=******* User_Name=******* Password=***** ODBCAdvanced=TrustServerCertificate=Yes; MARS=Yes Server=192.168.56.109 VariantFormat=String ExtendedMetaData=True ================================ FireDAC info ================================ Tool = RAD Studio 12 FireDAC = 29.0.51961.7529 Platform = Windows 32 bit Defines = FireDAC_NOLOCALE_META;FireDAC_MONITOR ================================ Client info ================================ Loading driver MSSQL ...

Depends on the complexity of the data needed to create the record(s). The our app can have many child records for a parent, but requires at least one child, so we use a 'wizard' type screen for creating these initial records. Our app is 25+yrs old, we have a mix of DB-aware for the the oldest forms, client datasets and even TMS string grids have been used to store data, but for 95% of all your 250+ tables we use one form for all create, view and edit of data. If a table contains multiple records we use a grid of some type with a panel that we show/hide depending on the status of the selected record to create/edit the data. We force the users to click an Edit button to change 99% of any data and then an Save or Cancel button.

You may want to look at frames. https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Working_with_Frames Different functionality and usage than creating a real component but may be what you are looking for. I have never used frames myself, but have several custom components to combine TEdit's, TComboBox's and TButton's into a TPanel that are added to a TScrollbox on the fly with different data in each.

Depends where the TFDConnection is defined, are you using a shared data module or creating it in the form? Is it pooled?

The problem is the procedure is declared to a class that does not exist: Should be: procedure TfrmDatabaseTutorial.ShowSelectResults();

We use a set of shared resource files, one for the EXE's and another for the DLL's (the filetype changes) and leave the IDE out of it. We have our own mass build process for production (the only time we care about the version numbers and things) with the option to update the version number, it changes and rebuilds the resource files before starting any compiles so we always have the correct versions for production.

No, not just for that feature I really like the component naming, renaming and replacement features. Makes migrating/upgrade older projects faster and the Tab Order as a tree saves time.

We prevent this issue with GExperts -> Set Component Properties and having it set the Active and Connected properties to False on all DB components before compiling. It does it automatically so we don't have to remember to do it 🙂 One of the best features of GExperts for us.

Your joking right? Is your database so large that it is not in a virtual server (hopefully on redundant hardware) with at least some sort of enterprise backup solution at a VM level? Is the client so small or so cheap they do not understand this is not a software vendors job? This sounds like a 'sales job' making you to come up with a solution for a non-problem or a completely incompetent IT service. I am betting on the latter. Sarcasm: Tell them they need an SAS 18TB LTO tape drive attached to the server and something old-school like Restrospec or Backup Exec installed on the server for file-level backups and about 10-12 hours of down time each night to do the backups. Don't forget to include someone has to swap that tape every day and they will need at least 100+ tapes for daily's, weekly's and monthly offsite storage. Maybe you should offer to pickup the backups every morning and keep them safe offsite for them, for a extra fee of course. Sorry I slipped into a 1990's rant there, just glad I do not have to deal with this type of thing anymore. Not making fun of anyone who still has to deal with tape backups I know their value to large organizations and disaster recovery plans.

We have also been using ReportBuilder Enterprise for 15+ years since QuickReports was not capable of somethings we wanted to do so many years ago. 100's of reports later and that doesn't count the 'End User' reports the users have created themselves. When COVID hit switching to emailing reports and invoice's saved so much time and paper, we have gone paperless and are not going back. We have not had any performance issues (that were not self-inflicted) and when we have had technical issues, support is fast and responsive with patches. I would also recommend ReportBuilder.
