debasisdas, great link again
Thanks for such a great explanation
nice and helpfull answers
pulkit007 thanks for this tip, looking for something like that for a while
SQL - Structured Query Language
I am doing something similar, very helpful answers here.
debasisdas, thank you very much for thoose links
I prefer NOT IN
and create a relation between keys
What if I want to select emplyees who have same country but they need to have different city?
Also two or more foreign keys can give you primary key.
Hm it is hard to tell....
Thanks for all the answers, I am solving the same problem.
Aren't primary keys always generated?
select department_ID, max(employee)
from department
I guess, maybe if you would give us more info, it will be easier
