I think your query is in error.  Amongst other things, tou have the same 
condition listed twice:

SELECT cl.ProjID FROM ProjectsMine cl JOIN ProjectsALL ls ON
(
   cl.id = ls.id AND
   cl.login = 'id0' AND
   cl.id = ls.id AND                 <<<< DUPLICATE
   cl.XtraB != ls.XtraB
);

You cannot return a result which does not exist, and if you delete id=10 from 
the ProjectsALL table there will be no project in either table that has id=10.  
How do you expect to return an id of 10 when that id does no exist?

What exactly, in English, is it that you are trying to achieve (ie, what is the 
PROBLEM STATEMENT for which you are trying to find a solution)?
