Mnesia question

[Mickael Remond]

Hi,

I have got a question about an error in my mnesia queries.



When I try to make a joint query on two tables I get this error message
:

=ERROR REPORT==== 25-Apr-1999::14:38:23 ===
!!! Error in process <0.188.0> on node 'master@REDACTED' with exit value:
nocatch
** exited: nocatch **


The code I am using for this query is :
task(User) ->
   Q = query 
         [ T ||
               T <- table(tasks), 
               U <- table(users),
               U.id = User,
               T.user_id = U.id ]
       end,
   F = fun() -> mnemosyne:eval(Q) end,
   mnesia:transaction(F).



The data is the database seems correct. When I make a simple query, the
function is working, but I did not manage to make this two tables query
to work.
Do you have any clue on what I am doing wrong ?

Thank you in advance.
