Hi,
It shouldn't be any issues.
I searched for it and found that it isn't a issue if we use just JOIN, but if we are using LEFT or RIGHT JOIN then this is issue as explained in lectures.
Hi Muhammad!
Thanks for reaching out.
The order of the tables does not matter as David pointed out. The order matters only when using LEFT / RIGHT JOIN.
Hope this helps.
Best,
Tsvetelin
