Query Documents from Azure Cosmos DB only returns on item

Hello,

 

I have a Flow retrieving data from Cosmos DB - if I run the below query in the Data Explorer of Azure, it returns two items:

SELECT * FROM c WHERE c.OrderID in ("123","456")

If I run the same query using Query Documents in Flow, it only returns 1 item:

I have tested this with various Order ID collections - sometimes providing 10 or 20 in the IN ("....", "...") statement and sometimes the Query Documents returns 2 or 3 items, but never the full amount. 

 

Appreciate this is a bit vague, but any idea what's going on and what could be the issue? 

 

Thank you,

Manuela

I got quite a few eyes on this for you, and ended up with the following suggestion. Please check to see if this works, if so, you may mark this as an acceptable solution.

 

Thank you for your patience as we investigated,

Recommendation:

There is ‘x-ms-continuation’ in the response of the operation. This string token is returned for queries if there are more results to be read. You may retrieve the next page of results by resubmitting the same request again with the ‘x-ms-continuation’ parameter set to this value (see red bordored area in the screenshot below).

Re: Query Documents from Azure Cosmos DB only returns on item

The query you're using within Flow probably has a formatting issue. As the Azure CosmosDB Connector documentation points out, the query parameter needs to be in string format. You may need to perform a convert to string expression - as it seems that only the first number in your query is returning.

If you provide us a detailed/expanded screenshot of your Flow, and any errors your Flow has we may be able to provide further assistance.

Re: Query Documents from Azure Cosmos DB only returns on item

Hi @ManuelaPichler ,

 

I was wondering if there would be a non-existent situation in OrderID you configured.

You could try to test each ID individually to get the expected items.

Use array variables to store these OrderIDs, then traverse the array, use Apply to each to query each ID to see if it can get the expected item.

Please take a try.

Re: Query Documents from Azure Cosmos DB only returns on item

Hello,

 

thank you for your reply! I have tried running the queries individually and all OrderIDs exist, I tried both IN and = on the query for an individual Order ID and it returned a record for all IDs that I tried to use in the concatenated IN. I also tried changing the IN statement to an Order ID = ... OR Order ID = ... and that didn't work either, only returning a subset.

SELECT c.SegmentDetails, c.Fulfillment , c.Seat, c.OrderDetails, c.Tickets, c.FarePrice  FROM c
WHERE c.OrderID IN ("individual number")

and

SELECT c.SegmentDetails, c.Fulfillment , c.Seat, c.OrderDetails, c.Tickets, c.FarePrice  FROM c
WHERE c.OrderID = "individual number"

It's also not a case of it always just returning 1 record, on the below query I'm passing in about 10 Order IDs and the action returns 2 items, despite all 10 existing.

Here's the action, the parameters get parsed in from PowerApps, but even if I hard code them directly in the query the result stays the same.
