I dont understand what I'm doing wrong in the following situation.
If I put this:
case(whens={exclude_table.c.minutes_limit != None:
exclude_table.c.minutes_limit}, else_=5000).label
(name='minutes_limit')
in the select clause of my query, I can't say:
having=(func.sum(cdr_table.c.duration) / 60) >= 'minutes_limit',
later on as I get the following error:
sqlalchemy.exc.DatabaseError: (DatabaseError) ORA-01722: invalid
number
I got around the problem by doing this:
stupid = case(whens={exclude_table.c.minutes_limit != None:
exclude_table.c.minutes_limit}, else_=5000).label
(name='minutes_limit')
and referring to "stupid" in the select clause and the having clause.
What is the right way of referring to the labeled CASE clause?
The complete query:
query = select( [cdr_table.c.nodeid_ingress,
node_table.c.deviceid,
customer_table.c.name,
stupid,
(func.sum(cdr_table.c.duration) / 60).label
(name='duration_minutes'),
location_table.c.datestarted,
location_table.c.dateended
],
and_(node_table.c.nodeid != None,
customer_table.c.customerid != None,
cloud_table.c.networkid == 1,
between(cdr_table.c.callconnected,
location_table.c.datestarted,
case(whens={location_table.c.dateended != None:
location_table.c.dateended},
else_=func.sysdate()))
),
from_obj = cdr_table.outerjoin(
node_table, node_table.c.nodeid ==
cdr_table.c.nodeid_ingress
).outerjoin(cloud_table, cloud_table.c.cloudid ==
node_table.c.cloudid
).outerjoin(node_contract_table,
node_contract_table.c.nodeid==node_table.c.nodeid
).outerjoin(location_table,
location_table.c.trunkid==node_contract_table.c.trunkid
).outerjoin(customer_table,
customer_table.c.customerid==location_table.c.customerid
).outerjoin(exclude_table, exclude_table.c.customer_name
== customer_table.c.name),
group_by=[cdr_table.c.nodeid_ingress,
node_table.c.deviceid,
customer_table.c.name,
'minutes_limit',
location_table.c.datestarted,
location_table.c.dateended],
having=(func.sum(cdr_table.c.duration) / 60) >= stupid,
order_by=[cdr_table.c.nodeid_ingress,
node_table.c.deviceid,
customer_table.c.name, 'minutes_limit',
location_table.c.datestarted,
location_table.c.dateended]
)
