Say I have a ContactDetails table with the following fields:
ContactID, ContactName, DateOfBirth, SpouseName, SpouseDateOfBirth, ChildName, ChildDateOfBirth (and some other fields not worth mentioning)
I pass in 2 parameters: eg. fromDate='19001111' and toDate='20071111'
If DateOfBirth is between fromDate and toDate I want to return ContactName and DateOfBirth
AND If SpouseDateOfBirth is between fromDate and toDate I want to return SpouseName and SpouseDateOfBirth
AND If ChildDateOfBirth is between fromDate and toDate I want to return ChildName and ChildDateOfBirth
If it is possible, how would a query look which returns these columns?
