Multiple Values Returned from Stored Proc

I need to return 2 values from a stroed proc. Can you have more than one
output parameters in a stored proc? If not, would bringing back a dataset b
e
better than two round trips to the database to get the 2 values I need?

Output variables are generally faster to return than generating a 1 row
result set. You can have more than one output parameter in a procedure.
I would tell you to determine if, in fact, the results should be
returned as a resultset or as output parameters. If you think that
additional values may need to be returned in the future or if you think
there might be a time when more than one row needs to be returned, it's
better to use a resultset so you don't have to mess with the interface
of the procedure.

a
suitable procedure to call to bring back two output parameters. If this is
correct, I will need to extend the Application Block to include a procedure
to do what it is I need. Is this correct?

I plead ignorance. I have never used the Microsoft Application Block for
DataAccess. I don't know how the object model looks. I assume it's a
high-level view of ADO.Net. Where do you define parameters for the
stored procedures. Make sure you're using the latest release, now called
the "Enterprise Library Patterns and Practices Library"
