Sql server 如何获取所有实例数据库的用户列表

我想程序应该是这样的：

declare @db varchar(100)
declare @user varchar(100)
declare c cursor for select name from sys.sysdatabases        

open c

fetch next from c into @db

while @@fetch_status = 0
begin
    print @db   
    exec ('use ' + @db)

    declare u cursor for select name from sys.sysusers
        where issqlrole <> 1 and hasdbaccess <> 0 and isntname <> 1

    open u   

    fetch next from u into @user

    while @@fetch_status = 0
    begin
        print @user
        fetch next from u into @user
    end

    print '--------------------------------------------------'
    close u     
    deallocate u    
    fetch next from c into @db
end

close c
deallocate c

但问题是exec'use'+@db不起作用。我总是得到当前所选数据库的用户列表。我该如何解决这个问题

备注：我希望此代码在2000和2005 sql Server上都能运行。

您也可以使用未记录但使用良好的sp_MSforeachdb存储过程-请参阅或参阅另一个：

那个？是将添加到命令中的数据库名称的占位符，因为它将针对系统中的每个数据库执行。

这里是一个很好的查询，如果您没有帐户，这是一个免费注册，也是一个非常好的资源

把所有东西都放在临时表中，然后你可以用它做任何你想做的事情

下面介绍如何创建SQL Server实例中所有数据库的所有用户的列表。我想这就是你要找的

如果您想要所有实例的所有数据库的所有用户的列表，您应该能够修改脚本来实现这一点。只需扩展脚本中使用的技术

+1太棒了！我试图找出一种方法，使stee1rat代码以某种方式工作，同时学习，然后你想出了这个强大的sp_MSforeachdb存储过程！谢谢太棒了！非常感谢你！现在，我可以使用一个简单的命令exec sp_msforeachdb'use？；轻松地删除所有数据库中的用户？；exec sp_dropuser testuser123”：我只是想知道为什么这个过程没有文档记录？它非常有用：如果LEFTCASTServerproperty'ProductVersion'作为VARCHAR1，1='9'替换为ELSE，如果LEFTCASTServerproperty'ProductVersion'作为VARCHAR2，2='11'，这一行在SQL Server 2012中仍然有效。当然，检查可以更一般化。
