来自Brent Ozar Unlimited网站的以下脚本遍历所有数据库,并按数据库列出孤立的用户,以及drop命令将其删除。可能有一种更整洁/更新颖的方式来处理此问题,但这似乎在2005-2012年正常运行。
DECLARE @SQL nvarchar(2000)
DECLARE @name nvarchar(128)
DECLARE @database_id int

IF NOT EXISTS
(SELECT name FROM tempdb.sys.tables WHERE name like '%#orphan_users%')
BEGIN
CREATE TABLE #orphan_users
(
database_name nvarchar(128) NOT NULL,
[user_name] nvarchar(128) NOT NULL,
drop_command_text nvarchar(200) NOT NULL
)
END
CREATE TABLE #databases
(
database_id int NOT NULL
, database_name nvarchar(128) NOT NULL
, processed bit NOT NULL

INSERT

我想首先感谢Mark发布脚本。从头开始编写它节省了我很多时间。由于遇到了一个错误,指出“数据库主体在数据库中拥有模式,不能删除”错误,因此我对其进行了一些修改。我修改了脚本以生成SCHEMA错误和Role错误的命令(如果您也应该获得该命令)。
希望这对外面的人有所帮助。
