Date function in Ingres DB

[Gabriel Tomoloju]

Hello guys,
How do i do i check in my where clause if:
a date_field in a table is less that 3 past months from today.
Note: I am using INGRES DATABASE

select * from tablename
where
date_field is less that 3 months from today.


Thanks.

Hi Gabriel,

It's a long time since I've used Ingres (6 or 7 years!), but if memory serves you can do it with something mad like:

where date_field < 'today' - '3 months'

It might be today() without the quotes, however. I'm pretty sure that today - 3 is 3 days ago. Try it.

Anyway, Ingres date stuff is (or was, at least) done using really nasty implicit conversion from strings. It makes the code read OK though.

Hope this helps.

Jules
