ERROR 1114: The table 'SQLb07dc_0' is full

[Chappuis J.-Vincent]

Hi,
I have this error when I execute a query : ERROR 1114: The table 'SQLb07dc_0' is full
I can execute other queries without problems but when I want to execute the query :

SELECT DISTINCT person.*
FROM person, training, cursus 
where training.BRANCH_ID=101
and training.CURSUS_SID=cursus.CURSUS_SID 
and cursus.STUDENT_SID=person.PERSON_SID;
 
there is always the same error message. 
How can I do to reset the table 'SQLb07dc_0' or to reset the sql buffer ?
 
Regards
