Constraints define the conditions or predictions under
which data is valid.
column level constraints are applicable to single column
only like if we want to make Unique constraint on column
level then as shoen below:-
<column Name><data type>Unique
At table level
Unique(<coulmn>,<column>);
Table level constraints means when constraints apply on
more than single column.
