Need help with select statement or query

Question

Not familiar with what to call it, but here is what i need...
To give our analyst a better idea of warranty on some of our
equipment, i
would like to add to the page a column that displays if the
device is still
under warranty
I currently capture the date the equipment was returned from
repair, so what
could i use within my select statement or query to display a
warranty
expiration date or display on the page...
example :
Returned from repair 10/20/2006 warranty expires on
11/20/2006
each equipment has different warranties, so i need a formula
or something to
say... device #1 has 60 day warranty ( so 10/20/2006 + 60days
=
12/19/2006 )
I would imagine this to be a query
Table 1 would contain the equipment type and warranty time
Table 2 would contain the current status of the equipment
Query would take the back from repair date + warranty =
expiration date

Answer 1

Simple. Join the two tables and create a derived column for
the expiration date. The exact syntax is dependant on your DBMS, so
check the manual for whichever you are using and look at the date
functions. There will be a function that will allow you to add a
number of date units (day, month, year, etc) to a date
field.
