DATE or is it DAY?

DATE or is it DAY?

DATE or is it DAY?

(OP)
Hello,
I am extremely new to Informix, so forgive me if my question is the most stupid one you people have had for a long time.
I am looking for a way to write 'yesterday'.
Suppose I have this querry: select * from TABLE where row_date='yesterday'. How do I write 'yesterday? I have tried DAY-1, DATE-1 but that does not work. Can someody point me in the right direction?

RE: DATE or is it DAY?

Try:

select whatever
  from table
 where datumsfeld=today-1;

Superb! Thanks, that helped.

Is there also a similar command for 'last month' ? Something like 'thismonth-1' ?

RE: DATE or is it DAY?

Bis:

Yes.  Use the internal Informix month function.  This command:

select * from table where month(datumsfeld) = 3

gets all data from 'table' where the 'datumsfeld' date column is march.  There's also corresponding day and year functions.

Regards,

Ed
