Find tables without a Primary Key

Find tables without a Primary Key

Find tables without a Primary Key

(OP)
Is it possible to query a whole schema and find which tables if any do not have a primary Key.

Thank you

Ian

RE: Find tables without a Primary Key

Sure

select a.table_name
from user_tables A
where not exists
(select null
from user_constraints b
where a.table_name = b.table_name
and B.constraint_type='P');
