Tsql T-SQL右键联接到选定列中的所有条目

我有下面的查询，它生成下面的输出

SELECT
    TBLUSERS.USERID,
    TBLUSERS.ADusername,
    TBLACCESSLEVELS.ACCESSLEVELID,
    TBLACCESSLEVELS.AccessLevelName
FROM
    TBLACCESSLEVELS INNER JOIN 
    TBLACCESSRIGHTS ON TBLACCESSLEVELS.ACCESSLEVELID = TBLACCESSRIGHTS.ACCESSLEVELID INNER JOIN
    TBLUSERS ON TBLACCESSRIGHTS.USERID = TBLUSERS.USERID

输出是这样的

29   administrator   1           AllUsers           
29   administrator   2   JobQueue                   
29   administrator   3   Telephone Directory Admin  
29   administrator   4   Jobqueueadmin              
29   administrator   5   UserAdmin                  
29   administrator   6   Product System             
27   alan            1   AllUsers                   
97   andy            1   AllUsers                   
26   barry           1   AllUsers                   
26   barry           2   JobQueue                   
26   barry           3   Telephone Directory Admin  
26   barry           4   Jobqueueadmin              
26   barry           5   UserAdmin                  
26   barry           6   Product System             
26   barry           7   Newseditor                 
26   barry           8   GreetingBoard              

我想做的是修改查询，以便获得所有访问级别，而不管该用户是否有条目。我还想做的是某种exist案例，这样我可以得到如下输出：

因此，规则总是显示AccessLevel的所有条目，并且ACCESSRIGHTS中存在的位置会生成一个true/false来显示这一点

我希望这是有意义的，希望您不需要表定义，因为我需要处理的所有内容都在原始查询中。我只需要一种方法来稍微操纵它，并在正确的位置获得连接

多谢各位。 步调

SELECT  u.USERID,
        u.ADusername,
        al.ACCESSLEVELID,
        al.AccessLevelName,
        CASE WHEN ar.accesslevelid IS NULL THEN 'False' ELSE 'True' END AS Access
FROM    tblusers u
CROSS JOIN
        tblaccesslevels al
LEFT JOIN
        tblaccessrights ar
ON      ar.ACCESSLEVELID = al.ACCESSLEVELID
        AND ar.USERID = u.USERID
