Hello, 
I would like to know if it is possible to query two tables from different DB in a single query. How can I do? The DB are both SQL. I just use KNIME therefore have not yet experienced. 
Thanks

Querying tables from different databases in one query is not possible (this is not a KNIME limitation, the databases just do not support it).
