without any specs or DDL, it looks like you have a split attribute
design error. Are "fixed" and "non-fixed" attributes of a work-space
or are they really separate entities? You posted another question
about using COALESCE() to combine two tables with a long list of
common attributes, so it is suspect.

A split attribute is having tables like MalePersonnel and
FemalePersonnel instead of Personnel. This leads to writing UNIONs and
tons of COALESCE() expression to build a correct set.
