问题描述
我正在使用一个 Oracle 数据库，通过 Oracle SQL Developer 和 R 与它进行交互.这个数据库在几个人之间共享，但由于某些公司规则，我们都使用同一个用户与之交互.
I'm working with an Oracle database, interacting with it both from Oracle SQL Developer and from R. This database is shared between several people, but because of some company rules we all use the same user to interact with it.
在我们的一个表中，我们发现了一种奇怪的行为，即在没有我们知道的任何顺序的情况下不断插入一行.
In one of our tables we found a strange behaviour, were a line is constantly inserted without any order that we know of.
比如说，在 Table1 上，有时有一行值 Name = "Test" 创建了超过 8K 次，我们无法弄清楚为什么会发生这种情况.
Say, on Table1, sometimes there is a line with value Name = "Test" created >8K times, and we can't figure out why is this happening.
我想要做的是创建某种自动机制(触发器)，当在 Table1 上插入 Name = "Test" 的行时，会保存执行此操作的查询和日期/时间.
What I wanted to do is to create some sort of automatism (triger) that, when a line with Name = "Test" is inserted on Table1 saves the query that did it and the date/time.
推荐答案
如果有搜索期的存档日志.您必须使用实用程序 LogMiner.示例 1.
If there are archive logs for the search period. You must use the utility LogMiner. Example 1.
EXECUTE DBMS_LOGMNR.add_logfile(LOGFILENAME => '/oracle/app/oracle/product/11.2/admin/edcu/arc_redo_log/1_39306_769799469.dbf', OPTIONS => DBMS_LOGMNR.NEW);
EXECUTE DBMS_LOGMNR.add_logfile(LOGFILENAME => '/oracle/app/oracle/product/11.2/admin/edcu/arc_redo_log/1_39307_769799469.dbf', OPTIONS => DBMS_LOGMNR.addfile);
EXECUTE DBMS_LOGMNR.add_logfile(LOGFILENAME => '/oracle/app/oracle/product/11.2/admin/edcu/arc_redo_log/1_39308_769799469.dbf', OPTIONS => DBMS_LOGMNR.addfile);
EXECUTE DBMS_LOGMNR.add_logfile(LOGFILENAME => '/oracle/app/oracle/product/11.2/admin/edcu/arc_redo_log/1_39309_769799469.dbf', OPTIONS => DBMS_LOGMNR.addfile);
EXECUTE DBMS_LOGMNR.START_LOGMNR(OPTIONS => DBMS_LOGMNR.DICT_FROM_ONLINE_CATALOG);
