How to search data from database on KNIME ?

Dear all, I have a sdf data, I want to know does this data exist in database! I use "SDF Reader" first , but I don't know how to connect the database and search the data ! Who can tell me what objects should I use on KNIME ? Wendy

Hi Wendy,

I think, the Database Looping node can help in this case, because it allows querying a database given a set of IDs.
