Question

I have the date when an article was created in a DB table. I have articles since the August until today.

I tried to create a SQL query, in ActiveRecord, to get the articles that were created today.

For example, today is the 14th of January and I tried to get those articles that were created on the 14th of August, 14th of September until today.

I tried something like this:

today = Date.today
day = today.strftime('%d')
day_next = (today + 1.day).strftime('%d')

Article.where('created_at >= ? AND created_at <= ?', day, day_next) #day = 14, day_next = 15

But this doesn’t return the right statement, because articles were released on the 14th of December and the 14th of October. This query returns me nothing.

Answer 1

You’re overthinking this. Assuming created_at is a normal datetime/timestamp field you should just convert created_at to its day using DAY() and then compare it directly to a normal Ruby Date object.

day = Date.today

Article.where 'DAY( created_at ) = DAY( ? )', day

# or just...

Article.where 'DAY( created_at ) = DAY( CURRENT_DATE() )'
