How to deal with PK and Sequence in Oracle? How to generate XML schema from an existing DB(oracle)?

[Annie Zhang]

Hi,

I have 2 questions:

I'm using oracle and torque. What's the best approach to use sequence to generate PK 
ID ?

How to use ant task "project-jdbc" to generate torque's xml database schema from an 
existing DB(oracle)?

thanks in advance.
