i have tested it now and i suppose result is wrong
 
------------------------------------
 
SELECT
EXISTS() return False
FROM
WHERE
...
 
------------------------------------
 
but
SELECT
NOT EXISTS() return NULL!!! instead of True
FROM
WHERE
 
------------------------------------
 
i suppose it is an error and should be reported to the tracker?
