One last try.
If there's a column called "shopping list" which is a comma-separated
list of items to buy in the store and I store '' in it. How many items
do you think that means you should go shopping for? Do you think
that's one item that should be rejected because it's an empty string?
Or do you think that's an empty list with zero items listed? </pre></blockquote><font color="#ff0000"><big>It can't be

What would it look like if it was a zero-length list? You can ask what
would it look like if it was a shopping list of one item called ''.
But I agree both are theoretically consistent, but one is actually
useful in 99% of use cases. The other is only useful in unusual cases. </pre></blockquote><br /><font
