Oracle 视图 ALL_TRIGGERS_AE 官方解释，作用，如何使用详细说明

本站中文解释

ALL_TRIGGERS_AE视图用于显示在当前用户或其它用户中已编译的Autonomous Transaction Processing（ATP）和传统数据库中的触发器，包括触发器的完整详细信息（trigger_type, triggering_event, table_owner,base_object_type,table_name, Table_type）。

使用ALL_TRIGGER_AE视图时，可以轻松地查询和管理当前用户或其他用户的触发器，以查看相应的详细信息：

–查询当前用户中所有表的管理触发器。
SELECT *
FROM ALL_TRIGGERS_AE
WHERE trigger_type = ‘MANAGE’
AND base_object_type = ‘TABLE’;

–查询所有用户中表的管理触发器。
SELECT U.username, T.*
FROM all_users U, all_triggers_ae T
WHERE T.trigger_type = ‘MANAGE’
AND T.base_object_type = ‘TABLE’
AND U.username = T.table_owner;
