Oracle version in the format of Maj.Min.V.Patchset? what have you tried? table defs? sample data? sample query? did it work? errors? get a book - if morgan stanley is your employer, no wonder we are in such serious financial trouble - we have ignorant people asking these sorts of questions. The good news is that ignorance can be cured with a lot of hard work and willingness to learn. Install OracleXE on a PC or Linux box (same thing :) ) and start testing and reading and more testing and reading. BTW - Google can be your friend too...
