Oracle 视图 REDACTION_VALUES_FOR_TYPE_FULL 官方解释,作用,如何使用详细说明
本站中文解释
Oracle视图 REDACTION_VALUES_FOR_TYPE_FULL 是一种数据屏蔽的快捷方式,它可以将敏感信息屏蔽掉。其中的REDACTION_VALUES表定义了要被屏蔽的数据以及屏蔽后需要显示的字符。
使用方法:
首先,创建一个REDACTION_VALUES表,其中包括被屏蔽的值、屏蔽后要显示的字符串以及被屏蔽值的数据类型 (注意区分大小写)。
然后,使用REDACTION_VALUES表中的数据,在Oracle数据库中创建一个名为“REDACTION_VALUES_FOR_TYPE_FULL”的视图,其中显示的列包括了被屏蔽的值以及屏蔽后显示的字符。
最后,在SQL语句中使用 REDACTION_VALUES_FOR_TYPE_FULL 视图,将 REDACTION_VALUES表中定义的数据进行屏蔽,从而保护数据的安全性。
