Is there any way to check for a field with nothing in it?

[Quoted] [Quoted] If I insert a new line, and put nothing into a particular field, what is its value? Is that what NULL is? (like, there's simply 0 bytes allocated for its space?)

How does one check for a NULL field, or ALL NULL fields in a particular line in a table?
