4 showed that SQL has an EXISTS keyword that corresponds to . There is no similar word in SQL to represent the in Listing 7-30. However, it is possible to rephrase statements containing every. The phrase every tournament has a corresponding row in the Entry table is the same as there is no tournament without a corresponding row in the Entry table. (I did say this could be a bit hard on the brain.) We can use this to rephrase our description of the values we want to retrieve: Write out the value of m.LastName, m.FirstName from rows (m) in the Member table where for every row there does not exist a row(t) in the Tournament table there exists for which there does not exist a row (e) in the Entry table with e.MemberID = m.MemberID and e.TourID = t.TourID. The equivalent expression in calculus notation for this alternative is shown in Listing 7-31.

Many scripts are simple one-offs that you write once, use, and forget. Others become part of your weekly or even daily use over time. When you find that you are using a script over and over again, you often find it helpful to pass in command line options. There are three main ways that this is done in Jython. The first way is to hand parse the arguments that can be found from sys.argv as we did above in chext.py, the second is the getopt module, and the third is the newer, more flexible optparse module. If you are going to do more than just feed the arguments to your script directly, then parsing these arguments by hand can get pretty tedious, and you ll be much better off using getopt or optparse. The optparse module is the newer, more flexible option, so we'll cover that one. The getopt module is still useful since it requires a little less code for simpler expected arguments. Here is a basic optparse script: Listing 9-12. # script foo3.py from optparse import optionparser parser = optionparser() parser.add_option("-f", "--foo", help="set foo option") parser.add_option("-b", "--bar", help="set bar option") (options, args) = parser.parse_args() print "options: %s" % options print "args: %s" % args running the above:

{m.LastName, m.FirstName | Member (m) AND NOT (t) Tournament(t) (NOT (e) Entry(e) AND e.MemberID = m.MemberID AND e.TourID = t.TourID) }
