Hello, I am quite new to KNIME and have found myself stuck with an SQL query issue. My 4 steps need to go as follows :
1)Establish connection to database
2)Run SQL query on database to retrieve information
3)Run another SQL query on top of the previously executed query to retrieve specific information
4)Write to file
Part 1 and 2 are running smoothly but I cannot figure out a way to apply the 2nd SQL query to the data set returned by the first SQL query. Is there a node that would allow this sort of workflow? I am trying to avoid using a correlated subquery(select within a select). Thanks for any help and please let me know if I need to clarify anything.
