Dynamic dates in queries can be much more useful than explicit dates because they are based on the current date. The following methods handle common scenarios. The following examples use the Domain Time Token token, but could also use the User Time Token or GETDATE().
This technique can be used to calculate a date N days ago, such as 7, 30, or 60 days ago.
dp_DomainTime - 7
MONTH([date_field]) = MONTH(DATEADD(m, -1, dp_DomainTime)) AND YEAR([date_field]) = YEAR(DATEADD(m, -1, dp_DomainTime))
MONTH([date_field]) = MONTH(dp_DomainTime) AND YEAR([date_field]) = YEAR(dp_DomainTime)
MONTH([date_field]) = MONTH(DATEADD(m, 1, dp_DomainTime)) AND YEAR([date_field]) = YEAR(DATEADD(m, 1, dp_DomainTime))
