Even without DB2 installed, you can read the documentation for it on the
web. There's quite a lot of useful info in IBM's docs. For example
http://nscpcw.physics.upenn.edu/db2_docs/db2s0/withsel.htm
and the example starting at
http://nscpcw.physics.upenn.edu/db2_docs/db2s0/db2s0446.htm
(The docs are probably also readable directly from IBM, but this is the
first copy I found by googling...)
