NOTE: You will need to execute the SQL statement below in
order to copy the ‘customers’ table (f_customers). This will
leave the f_customers table as is, while you modify the copy
(copy_f_customers).
CREATE TABLE copy_f_customers
AS (SELECT * FROM f_customers);
Table copies will not inherit the associated primary-to-foreign-
key integrity rules (relationship constraints) of the original
tables. The column data types, however, are inherited in the
copied tables.
If a change is not possible, give an explanation as to why it is
not possible.
