Answer Posted / rajan sharma
Column level are those constraints that are inserted after
the declaration of the data typeot
Syntax :
CREATE TABLE table_name
(Column_name Datatype NOT NULL )
Example : Not null,pimary key,foreign key, unique and check.
Table level constraints are those that are inserted at the
end of the table.
Example : pimary key,foreign key, unique and check.
