Oracle：如何知道列何时添加到表中？
请问，当一列被添加到表中时，我是否可以检索历史记录？我现在在看倒叙。谢谢。您可以使用Oracle：如何知道列何时添加到表中？,oracle,Oracle,请问，当一列被添加到表中时，我是否可以检索历史记录？我现在在看倒叙。谢谢。您可以使用用户/所有/DBA_对象表来查找对表所做的最后更改。见下文： SELECT OBJECT_NAME, OBJECT_TYPE, TO_CHAR (CREATED, 'DD-MM-YY HH24:MI:SS') CREATED, TO_CHAR (LAST_DDL_TIME, 'DD-MM-YY HH24:MI:SS') LAST_DDL FROM USER_OBJEC
