Maybe this time I have nothing important to do, so, I was thinking about a Query that could break your patient and system resources, can be this Query the Wrost <g>???

   CREATE CURSOR Temp (ID i)
   FOR I=1 to 600000
       INSERT INTO Temp VALUES (RAND()*100)
   ENDFOR
   
   **** This is the Wrost Query ****
   SELECT * FROM Temp WHERE ID ;
        IN (SELECT ID FROM TEMP WHERE ID IN(RAND()*100, RAND()*100))
