注解

只能HistoryRetention由分发数据库上的 或replmonitor固定数据库角色的成员db_owner、发布访问列表中的用户 (PAL) 分发数据库检索，或者由对分发数据库中的 MSdistributiondbs 系统表具有 SELECT 权限的用户检索属性。

属性 HistoryRetention 只能由分发服务器上的固定服务器角色的成员 sysadmin 设置。

检索 HistoryRetention 属性等效于执行 sp_helpdistributiondb。

HistoryRetention设置 属性等效于执行sp_adddistributiondb或sp_changedistributiondb。
