I have a table with several columns.

Sometimes some of these column fields may be empty (ie. I won’t use them in some cases).

My questions:

  1. Would it be smart to set them to NULL in phpmyadmin?

  2. What does the “NULL” property actually do?

  3. Would I gain anything at all by setting them to NULL?

  4. Is it possible to use a NULL field the same way even though it is set to null?

    1- Would it be smart to set them to
    NULL in phpmyadmin?

    All fields are null by default unless you specify a default value for them or insert some value for them. No need to do this…

    2 -What does the “NULL” property
    actually do?

    Null means that you have not assigned any value to it.

    3- Would I gain anything at all by
    setting them to NULL?

    As said before, all fields are null by default unless you specify a default value for them or insert some value for them. I don’t think you are going to gain anything.

    4- Is it possible to use a NULL field
    the same way even though it is set to
    null?

    What would you gain out of a field having value of NULL? No need for this too.
