Chapter 8. Iterative Control
In this chapter you learned about simple loops, WHILE loops, and numeric FOR loops. You also learned that all these loops can be nested one inside another. Here are some projects that will help you test the depth of your understanding:
1)
Rewrite script ch08_1a.sql using a WHILE loop instead of a simple loop. Make sure that the output produced by this script does not differ from the output produced by the script ch08_1a.sql.
2)
Rewrite script ch08_4a.sql using a simple loop instead of a numeric FOR loop. Make sure that the output produced by this script does not differ from the output produced by the script ch08_4a.sql.
3)
Rewrite script ch08_6a.sql. A simple loop should be used as the outer loop, and a WHILE loop should be used as the inner loop.
The projects in this section are meant to have you utilize all of the skills that you have acquired throughout this chapter. The answers to these projects can be found in Appendix D and at the companion Web site to this book, located at http://www.phptr.com/rosenzweig2e. Visit the Web site periodically to share and discuss your answers.
