[Zope] What's the return object after calling a SQL Method?

[T. C. Huang]

Dear Zoper:

  What's the return object when one runs a SQL query? How can one
accesses the return object for further processing in another DTML
Document?

  By using Z Search Interface, I can get a tabular query report after a
SQL query method. How can I do if  I want to get one of the items in the
report for further processing in another DTML Document (for example, I
want to update some column value of the selected record)?
