Need Homework Help SQL ASAP

Hello
I need some help with this assignment. I have to modify the PRODUCT_t table by adding an attribute QTY_ON_HAND and can be used to track finished goods inventory. The field should be an integer field of 5 characters and should accept only positive numbers. So far I have something like this:

INSERT into PRODUCT_t
(QTY_ON_HAND, )
("3", integer(5));

Could someone please show me how to write the entry.

Thanks

Think you need ALTER TABLE command. Check this link:
