問題文
A developer replaces the query a Source Qualifier transformation would have built with one typed out by hand. Entries for a join and for a test on the arriving rows had already been filled in on the same object, and the team has to say what becomes of them. In the same mapping an Expression transformation has to work out several different figures, and the team has to say how many expressions one such object will carry. Which pairing states both?
