Ramesh Reddy commented on TEIID-2983:
-------------------------------------
Is there a way re-write multiple aggregate statement above? right now I can only think
that that needs to split into two statements.
MongoDB can group by multiple elements in a group, then we can do a sum like
{code}
{$group:{ "_id" : {col1:"foo", col2:"foo2"} ,
"_m0" : { "$sum" : 1}}}
{code}
but not sure the it equals to
select count(foo1), count(foo2) from bar
Right now I set to ignore the second aggregation on hind sight, but may be I can throw an
exception in that case to show translator does not have support. I probably should also
support DISTINCT case there.
MongoDB: Function "count()" returns sum instead of number
of rows

Project: Teiid
Issue Type: Bug
Components: Misc. Connectors
Affects Versions: 8.7.1
Reporter: Van Halbert
Assignee: Ramesh Reddy
Labels: Beta1

Function "count()" returns sum of rows instead of number of rows
Query [1] returns sum of values of all rows of IntKey column.
Query [2] correctly returns number of rows
