sql - 加入 oracle 元数据表

Question

我正在尝试加入元数据表以查询表上的统计信息，例如触发器计数、序列、包、过程、视图等，但我找不到加入表的键。这是我的查询

SELECT * 
FROM user_constraints   a
    JOIN user_tables    b ON a.table_name = b.table_name
    JOIN user_triggers  c ON a.table_name = c.table_name;

我想做一个大查询来拉回所有主要元数据表中的所有数据谢谢

尝试这个：

-- constraint references
select to_char(sysdate, 'DD-MON-YYYY') date_evaluated
