Oracle中查询该表中的主键被哪些表引用，该表中的外键来源于哪些表

Oracle中查询该表中的主键被哪些表引用的SQL语句 select c.TABLE_NAME   from all_constraints p, all_constraints c  where p.table_name = '表名'    and p.OWNER = SYS_CONTEXT('USERENV', 'CURRENT_SCHEMA')    and c.OWNER = SYS_CONTEXT('USERENV', 'CURRENT_SCHEMA')    and c.constraint_type = 'R'    and p.CONSTRAINT_NAME = c.R_CONSTRAINT_NAME

oracle中查询该表中的外键来源于哪些表的SQL语句：

select cl.table_name   from user_cons_columns cl   left join user_constraints c     on cl.constraint_name = c.r_constraint_name  where c.constraint_type = 'R'      and c.table_name = '表名'

PS：查询owner的SQL语句： select SYS_CONTEXT('USERENV', 'CURRENT_SCHEMA') from dual
