You need to output only a list of field names, arranged in a single column, for a reporting function. You have already imported the data using a Database node and know it has 25,000 records.

Which node sequence would yield the desired output?

Which node will you use to accomplish this task?

You want to illustrate the strength of the relationship between blood pressure and prescription drug to which a patient responded. The blood pressure variable has been binned into ten values.

Which node should be used?

Which node will exclude the undesired records?
