Hi,
I'm having some trouble figuring out the best way to fetch data from a
selectable stored procedure on a PG database.
The only solution I found is the following::
results = metadata.engine.text(
'select iddip, day, amount '
'from diary(:iddip,:fromdate,:todate,:live)'
).execute(iddip=iddip, fromdate=fromd, todate=tod, live=True)
that does indeed return what I need. I can easily decorate the raw sql
with some joins and I'm done.
OTOH, this seems a little ugly, and I wonder if a better, more alchemic
approach exists.
I tried to get there using select(), for example::
results = select(['iddip', 'day', 'amount'],
from_obj=[
"diary(:iddip,:fromdate,:todate,:live)"],
engine=metadata.engine
).execute(iddip=iddip, fromdate=fromd, todate=tod, live=True)
but that gave me a KeyError on 'iddip' no being given.
Given that for all practical purposes such an SP is equivalent to a
Table + an intrinsic set of bindparams, how can I best express and use
such a source of data in SA?
Thanks in advance for any hint, and of course for a great product too!
bye, lele.
