Thanks for the update.

FireDac Array DML Update query - omitting certain fields
weirdo12 replied to Mark Williams's topic in Databases
If you want to be as flexible/portable as possible you could consider using a FireDAC macro like this: email = { fn IFNULL(:EMAIL, email) } -
FireDac Array DML Update query - omitting certain fields
weirdo12 replied to Mark Williams's topic in Databases
😄 So just supply the current value when the value doesn't change. I do like the statement that uses COALESCE because it makes it very obvious that that is what is happening. Are you targeting a specific database server? -
They are retooling the C++ compiler chain. I get the impression that C++ is becoming more important - not less - even if it might seem like a 2 steps forward, one step back (for the moment). My gut feeling is the future has never been brighter for C++Builder.

Why not just supply the current value where you don't want a value to change? -
Thank you, Roger.

We still use an old Northern Telecom phone system and have an operational fax machine on a stand alone line here at work here in Toronto. 😄 -

Great to hear that things are getting fixed up! -

I'm still surprised it hadn't been mentioned already as a possible cause... -

I just did a search of the terms 'ransom' and 'ransomware' and they haven't appeared in this thread. I'm kinda surprised. 😉 You'd think that the documentation would be back up by now. -
FDTable: EFDException with message '[FireDAC][Stan][Eval]-117. Empty expression'
weirdo12 replied to Stano's topic in Databases
Thanks for the update. -
You can build your file name like this as well: var file_name : String; file_name := TPath.Combine('D:\Delphi_11_Community\MyProjects\Dinobase\dino_images', sName); file_name := TPath.ChangeExtension(file_name, "jpg"); dinoImage.Picture.LoadFromFile(file_name);

Drop a TFDQuery component on your form. If it's the first one, it will be named FDQuery1. Set FDQuery1.Connection property to the TFDConnection you use to connect to the SQLite database. Then, in your code, replace Query. with FDQuery1.

[FireDAC][Phys][ODBC][Microsoft][ODBC SQL Server Driver]Connection is busy with results for another hstmt
weirdo12 replied to gkobler's topic in Databases
In the version that works, what happens if you don't call fdqImportData .Close after copying the data to the TFDMemTable? -

I'm glad you found a solution. You could have a look at this thread and see if there's anything that might help with the original problem: -

weirdo12 replied to gkobler's topic in Databases
And you are using the MARS=Yes parameter on the connection? Have you tried version 17 of the SQL Server ODBC driver? -

Try executing you commend on your TFDConnection and see what you get: FDConnection1.ExecSQL('UPDATE dbo.TDexAllocationTicketOut SET ReadDT = GETDATE() WHERE IDInt = :idInt', [fdqImportData.FieldByName('IdInt').AsInteger]); You might have to fix my Pascal. I didn't test it. -

Why do you need to use the mydb schema name?
-
Can you copy and paste or attach all of your .pas source code here once again.
-
schema-name == The database in which the new table is created. Tables may be created in the main database, the temp database, or in any attached database. https://sqlite.org/lang_attach.html

It's weird. If I send multiple PDF attachments using smtp.outlook.com or smtp.office356.com, all attachments appear identical to the last file attached. For example, if I send 3 attachments, the first 2 will appear to contain the contents of the last file that was attached to the email. The file names are not altered. I've tried sending .ini and xls files too. Same thing happens. I can send a message as expected using smtp.gmail.com, Mailjet, SendGrid and our ISPs smtp server. Nothing in my code detects what server is used to send a message.
