Hi...
Zitat:
The error was in the connection settings
This is what i mean with the INI File. If is the connection hardcoded...what happens when you give your friend the EXE? Exactly that... That's why the settings should be written to an INI.

Zitat:
There is only one last question
The difference is:
With a table all records are always read...even those from 10 years ago.
With a qery you can get only the records of the last year...if you want.
Otherwise the "operation" is the same...
Zitat:
We write two queries the first to show the students and their grades And the other to show the students and their group or only one query ?
If you want so... The SQL, with a query, creates the data.
Zitat:
because if we write one query the result it will be wrong
This not a TQuery problem...it a SQL problem. Also the database structure must fulfill rules. (ForeignKey) I dont know what you want to see...
SQL information (you know):
https://www.w3schools.com/sql/
Database information:
https://en.wikipedia.org/wiki/Database_normalization
Zitat:
I almost visit GitHub website and i didn't know it is a repository
Once again to Git:
You don't have to use it. But you can use it to view the changes since the last save in the repositoriy. See picture1. More important is that you can reset the changes.
GIT is decentralized. You have one repository locally and one "copy" externally (GitHub, BitBucket)
You start only locally with GIT. (Setup: GIT + GUI Tool TortoiseGIT). Only if you cooperate with others, it is necessary to store the source code externally.
What is GIT:
https://fr.wikipedia.org/wiki/Git

Difference Tool:
BeyondCompare ...shipped with Delphi.

...to much?

Who says programming is easy? You have to learn every day.
