Looking to learn something new?
If I get a set of values from a database and one of the values is NULL will it do any harm if I don't do anything to it?
I'm getting an array of values from a database and I'm using those values in multiple scenarios, the database always returns the same columns even when it returns NULL, it's worth noting that when the column returns NULL that column is not used in any way, shape or form. I could write a function so that the database doesn't return NULL on empty columns but that would be way too many lines of code but I'm not even sure if it does cause any problems. Because if not it's not even worth doing it.
So... will it bring any kind of problems to the website? Thanks in advance.
