可以依照SCHEMA展出没有设PK的TABLE
def schema_name = &&owner_name
col sname format a30 heading 'Schema'
col tname format a30 heading 'Table Name'
select
dt.owner sname,
dt.table_name tname
from
sys.dba_tables dt
where
dt.owner like upper('&schema_name') escape '\'
and
not exists
(select 'x' from sys.dba_constraints dc
where dc.owner = dt.owner
and dc.table_name = dt.table_name
and dc.constraint_type = 'P')
order by 1,2
/
执行结果
Schema Table Name
