SQL Subquery column equals operation

I am trying to do a SQL query for user with certain permission enabled flag. I know, I can do this:

select u.ID, u.Name, 
   (select p.Value 
    from Permissions p 
    where p.UserID = u.ID AND p.Key = 'CanEdit') as IsPermissionEnabled
from Users u

But it's not exactly what I need, can I do something like this:

select u.ID, u.Name, 
   ((select p.Value 
    from Permissions p 
    where p.UserID = u.ID AND p.Key = 'CanEdit') = 'True') 
   as IsPermissionEnabled
from Users u

It didn't work for me. So, how to change my query to make it work?

Best How To :

Try this query

select u.ID, u.Name, case when p.value>0 then 'True' else '' end   
   as IsPermissionEnabled
from Users u
left join permission p on p.UserID = u.ID and p.key='CanEdit'
