QUEL is more powerful than SQL.

Reasons: (Behold!  All yee IBM people...):

- QUEL is *proven* to be funtionally equivalent to the relational
  algebra.  Therefore, anything that can be expressed in the relational
  algebra can be expressed in QUEL.

- QUEL is more consistent in its design (talk to E. Wong about it).  In
  SQL, problems are solved ad hoc instead of being part of the initial
  design.
