there's a way....
def executesql(self, query, placeholders=None, as_dict=False, fields=None,
colnames=None)
taken straight from docstring
*The "fields" argument is a list of DAL Field objects that match the
fields returned from the DB. The Field objects should be part of
one or
more Table objects defined on the DAL object. The "fields" list can
include one or more DAL Table objects in addition to or instead of
including Field objects, or it can be just a single table (not in a
list). In that case, the Field objects will be extracted from the
table(s).
Instead of specifying the "fields" argument, the "colnames" argument
can be specified as a list of field names in tablename.fieldname
format.
Again, these should represent tables and fields defined on the DAL
object.
It is also possible to specify both "fields" and the associated
"colnames". In that case, "fields" can also include DAL Expression
objects in addition to Field objects. For Field objects in "fields",
the associated "colnames" must still be in tablename.fieldname
format.
For Expression objects in "fields", the associated "colnames" can
be any arbitrary labels.
Note, the DAL Table objects referred to by "fields" or "colnames"
can
be dummy tables and do not have to represent any real tables in the
database. Also, note that the "fields" and "colnames" must be in the
same order as the fields in the results cursor returned from the DB.
*
meaning basically that if your select returns 3 columns, id, name and event
of the table "whatever" you can get the "usual" object back from executesql
using either
fields = [db.whatever.id, db.whatever.name, db.whatever.event]
or
colnames = ['whatever.id', 'whatever.name', 'whatever.event']
Not sure if it's enough to trigger the json creation.
