Hi Everybuddy,
I am having a little problem I can not find a solution for.
I am trying to use the SQL-LIKE statement in gadfly. After googling
around I found out that it is not supported, and that on is supposed to
use a regular expression. All great, but there is nowhere a reference
to be found on how to do this. No examples, no nothing, just the
comment to use regular expressions.
As it currently stands what you need to do is evaluate the query
using gadfly, pull the query out into "normal" python, and then use
a python loop and string operations (such as regular expressions) to
choose the results you want (and throw out the others).
This will work for analogues of simple positive queries such as
select a,b
from t
where c like '%this%'
but may not for fancy queries involving "not in" and so forth -- which
would require a proper implementation of "like" in gadfly. Sorry.
Probably the "right" way to fix this is to allow the importation of an
arbitrary function into gadfly from python, which wouldn't be too hard
but isn't trivial.

ps: my copy of MSAccess doesn't support "like" properly either, fwiw...
