query would result in illegal record length

  Explanation:  Solving  the  user's  query  would  result  in  an
  illegal record length being used for an RMS operation.

  User Action:  The user will  have  to  reconsider  the  database
  design,  environment  or  query  structure.  This error would be
  obtained as the result of a conjunct match strategy  which  does
  not  have  enough VM.  This can be resolved by providing a large
  enough value for the logical  RDMS$BIND_WORK_VM).   Alternately,
  the  problem  might  be alleviated by dropping the indices which
  are used for query resolution or by reducing  the  size  of  the
  columns being joined.
