Thanks for the answers.
The example was from the Zope Book.

employee_by_id -> Z SQL Method
emp_id -> Parameter key for employee_by_id
2 -> Parameter value for emp_id

The result of employee_by_id(emp_id=2) is a SQL
result. 

viewEmployee -> DTML Method

viewEmployee will use the result of the above
employee_by_id Z SQL Method and render the variables
first,last and salary to HTML, if I call the URL from
a browser.

But, giving the same URL
employee_by_id/emp_id/2/viewEmployee as a tal
expression like

tal:content="structure
employee_by_id/emp_id/2/viewEmployee"

will render nothing. There is also no error messages. 
Do you know what happens?

Thanks,
Ferhat
