Access to QRDS and the MySQL table in one query

I have setup QRDS, I can use it.
For example, I have made a query that returns to me a list of specific collections.
I can access to the results by a query
SELECT * FROM query_63
And it works well.

After that, I have to query from another big table in DB, but only from the records where CollectionID is in the List.
I made a simple query:
WHERE CollectionID IN (SELECT * from query_63)`

But it can not receive the result, because if I choose the source the MySQL - it can not see the QRDS source. How can I point to the QRDS source from the query?

Error running query: **Table 'videodb.query_63' doesn't exist**
