Oracle删除表时候有外键 不能删除

 

SELECT
    A .constraint_name,
    A .table_name,
    b.constraint_name
FROM
    user_constraints A,
    user_constraints b
WHERE
    A .constraint_type = 'R'
AND b.constraint_type = 'P'
AND A .r_constraint_name = b.constraint_name
AND A .constraint_name = UPPER (
    'ACT_FK_VAR_PROCINST'
)

找到对应表 直接删除
