## Logical Functions: IsGeneration(): Conditional Logic within Calculations - Page 3May 7, 2007
Per the request of our client colleagues, we will first construct
a simple query to provide an illustration of the use of the 1.
Type (or cut

The
The above query returns the Recall that we have said that we might accomplish our ends
through alternative methods. The approach we are taking here allows us to
parameterize either or both of the In the

contextual backdrop we have established for introducing the In recalling the requirement, the analysts tell us that,
among other averages under immediate consideration, one need involves The developers / authors within the group cite the foregoing
example as useful, once again, in the exploration of a function with which they
are becoming familiar. They would like to extend their understanding of the IsGeneration() operator, once
again within the definition of a calculation based upon conditional
logic, to meet this end. 4.
