The new version of KNIME is looking great! I’ve already been able to simplify a number of my workflows, but there’s one function that I’m struggling with.
How do I execute a SQL query against each element in a column of data and return the results to a new column?
In PL/SQL, I would use something like:
cursor data_c is select data from table_knime;
fetch data_c into v_data;
exit when data_c%NOTFOUND;
select column from table_oracle where column = v_data;
The new Database Looping node doesn’t seem to be quite what I’m looking for. For a given column of data, it processes a request as :
select * from table_oracle where column in (data1, data2, data3,…)
Am I using this node incorrectly, or is there another way to loop through each element in a column and run the query only against that element?
