I'm not able to make not null constraints

[@muhammadyasar9764]

Thank you sir.

I have a doubt, if we we want to drop the constraint that has been applied to column 2, can it be done? If so, how? Because we have not assigned a constraint name for the col2.

Why not null constraint can only be passed at column level plz explain

[@gauravchandrawale7021]

Coz we first create ttable ...and table is always empty...after creating table we put data into the column

[@shaheenshaikh6701]

Why we used modiy firstname why alter table employees add constraint constraint_name cons_type .

[@nikitakumari-rv7li]

Why not null constraint is column level constraint and not table level constraint?
