I Need to write a qurey to sum one field according another field. For
example, I have a table with name, job and salary. I want to get a table 
with name and salary only. Each name will have only one entry here and the
salary will be the summation of all his job. How to write the Postquel ?
Is there any good tutorial about POSTQUEL ?

Thanks

Shuo-jen Wu
