i am new at sqlserver and i just started learning it , and i have a question .
**i want an SQL query that can bring up all rows that were added in the past 6 months. in table ‘users’ the date is in field ‘joined’ but its in UNIX time stamp format

**and i want then like another SQL query the same as above but it also with the results sets the field ‘activate’ in each row to ‘yes’

i tried that code :

select * from users where time_of_post is like '07/**/2011'

** = anyday but i can`t implement it right .

Thank you a lot for your help in advance .

    select *
from users
where datediff(mm, time_of_post, getdate()) <= 6

    What you want to use is the DATEDIFF() function, and get the difference between today’s day (GETDATE()) and the stored dates (time_of_post). If that is less than or equal to 6 months (as denoted by the first parameter, mm) then that should be what you’re looking for.

    EDIT:

    If you’re looking to use this logic for an UPDATE, you’d do something like this:

    update users
set activation = 'yes'
where datediff(mm, time_of_post, getdate()) <= 6
and activation <> 'yes'
