Hello
I have two tables "Uczniowie" and "zdawalnosc" table "zdawalnosc" is empty and needs to do the query that will help in addition to her.
The problem is that when I needed to just "uczenid" I have used LEFT JOIN and it was on, and now I have two columns which needs thus to add.
When I had a relationship sql script looks like this:
Code:
SELECT Uczniowie.*, zdawalnosc.*
FROM Uczniowie LEFT JOIN zdawalnosc ON Uczniowie.Identyfikator = zdawalnosc.uczenid;
but how to do it with two relationships?
