Switch operator - how does it work?

Hi Experts,

the switch-operator is available in VC 7.0 since the last service pack, too. Unfortunately, I don't really understand how it works.

Can somebody give a detailed example on how it works? I couldn't find any useful hints in the other forum, so I post it here.

I have the following requirement:

Query A deliveres prices in currency A, Query B deliveres the same prices, but converted to currency B.

Depending on the user that logs on, I want to "pour" the data from Query A into my model or the data from Query B.

Is this a possible scenario for the use of the switch-operator? How would I do it?

Thanks in advance and best regards,
