Hello @Arunkumar ,

Thanks for the question and using MS Q&A platform.

Could you please run the same query in Azure Cosmos DB => Data Explorer and see if the query works as excepted?

You can run the same query on ADF data flows as shown below:

SELECT * FROM [items] - throws error message
SELECT * FROM items - works as excepted

In case, if you are still facing the same error message, could you please share the complete error message which you are experiencing along with the screenshot?

Hope this will help. Please let us know if any further queries.

Hello @Arunkumar ,

The collection is selected on the Dataset level and not at the query level.

Note: Case is the collection name and not the items available in the collection and the query should be SELECT * FROM c or SELECT * FROM items.

Hope this will help. Please let us know if any further queries.
