Dear Friends,
I am very new to KNIME and trying to connect MongoDB through MongoDB reader to extract few data from the collection.
But I am receving the below error:
“ERROR MongoDB Reader 2:1 Execute failed: Cannot parse query:db.getCollection(‘callingbatchdetails’).count()”
Able to successfully execute the above query through MongoDB.
Please help…
Can anyone guide where am i going wrong in using the MongoDB reader component
I only gave the MongoDB nodes a quick attempt a while ago, but as far as I remember you can only perform .find() operations. As they don’t support aggregation queries either, I’m not sure whether there’s any viable workaround.
Without wanting to sound harsh, but I found them hardly usable for any real-world use cases.

is there any other alternative available in KNIME through which i can connect to MongoDB.
The node’s description states that it uses Jongo as the query language which is different from the Mongo shell language.
Hi,
I tried using the mongo query language as well but getting the same error. Can you please guide.
