MySQL returning Zeros when no data entered
We are developing a System for educational institutions. In this system, MySQL has been returning zeros whenever no marks are entered for a particular exam. How do we go round this problem because it shouldn't always be returning zeros when no mark has been entered. It should only do so in cases where it should but not in all cases.
How can we get round that problem?
