Обсуждение: Wildcard in date field???

Hello,

I need to make a query that will select items that have a date matching
the current month for example.

For June this means that any day between 2000-06-01 and 2000-06-30 are
ok. To do that I need a wildcard like "%" to replace the actual day in
the date field.

Ex.:  select * from item where date = '2000-06-%%';

but that doesn't work... What is the right way?

Thanks!

SELECT  * FROM my_table WHERE date_part('month', col_name::datetime) = '06' 
AND date_part('year', col_name::datetime) = '2000';

Looks for more detail in the manual for "date_part"

Multiple ways to do it, but here's one:
select * from item where date_part('month',mydate) = 6   and date_part('year',mydate) = 2000;
