是否可以找到在Oracle数据库的表中创建特定行的日期。 （在列中未插入创建日期时间）。
答案 0 :(得分：1)
您可以在查询中使用ORA_ROWSCN伪列。看：
SELECT SCN_TO_TIMESTAMP(ORA_ROWSCN), last_name FROM employees
WHERE employee_id = 188;
还请查看有关以下内容的文档：https://docs.oracle.com/cd/B19306_01/server.102/b14200/pseudocolumns007.htm

如果在Oracle RDBMS上启用了插入日志/审计功能，则可以。
AUDIT INSERT, UPDATE, DELETE ON MySchema.MyTable BY ACCESS;
然后开始审核日志以进行记录。此刻之后，您可以从
查询select * from sys.aud$

例如1.插入。使用闪回功能。
insert into test2(p1,p2,p3)
values(1,'test_insert','test')
==>
1 row(s) inserted
SELECT versions_xid XID, versions_startscn START_SCN,
versions_endscn END_SCN, versions_operation OPERATION,
p1, p2, p3, ROWIDTOCHAR(ROWID)
FROM manager.test2
VERSIONS BETWEEN SCN MINVALUE AND MAXVALUE;
XID, START_SCN, END_SCN, OPERATION, p1, p2, p3, ROWIDTOCHAR(ROWID)
