Hi Joey great video
Is it possible to have a many to many relationship in self join tables, for example if a employee has 2 or more managers
Suppose we have 3 server, in this servers all the databases and tables name can we retrieve ?
Thanks
Do you create employee-I’d as primary key and managerid as foreign key? If so How these number would be not unique?
Thanks for this, is there a video for categorical data?
Couldn't understand is null part...
