This is the ANSI standard, and if I understand correctly, this one has been implemented by other RDBMS vendors as well. When comparing the connect-by with the recursive with, I noticed a difference in the result set when using cycle detection. The connect by results are more intuitive to me,

问题 On AS400 in interactive SQL in a 5250 session, select * from myfile returns rows from one member only when myfile has more than one member. How can I get rows from a specific member?
