Calculations in a query

[jmmmmm]

I would like to do a date calculation between 2 fields in the query and return a result based on the calculation:

ex:

table x
field date
field duration


SELECT * FROM x WHERE [date + duration] >= (somedate)

Is this possible?

yes that is possible, you need to join both the tables for same.

hi
your query is possible if the duration is number of days only.

if you want to calculate for different kinds of duration like days, weeks, months and years then

-- duration is number of days
SELECT * FROM x WHERE DATEADD(day, duration, date ) >= (somedate)
-- duration is number of weeks
SELECT * FROM x WHERE DATEADD(day, duration * 7, date) >= (somedate)
-- duration is number of months
SELECT * FROM x WHERE DATEADD(Month, duration , date) >= (somedate)
-- duration is number of years
SELECT * FROM x WHERE DATEADD(year, duration , date) >= (somedate)
