Question

I have a table that has a column with the timestamp in sqlite3. It is default to the CURRENT_TIMESTAMP such that when the row gets inserted, the current time is inserted. Now I am trying to fetch the rows that have been inserted 2 days ago or more. I wonder if that makes any sense.

Reading the documentation I came up with:

SELECT * FROM test WHERE timestamp < strftime('%s', '-2 days')

but apparently that’s wrong. I came up with this query because that is similar to the way in which I am doing the test in my actual code:

strtotime($timestamp) < strtotime("-2 days").

But I was hoping that sqlite3 included some built-in checks for this type of situation.

Thanks, I appreciate any responses.

EDIT: Figured it out: SELECT * FROM test WHERE timestamp < date('now', '-2 days')

I’ll keep this open in case someone can come up with something better.

Answer 1

So I think I figured it out, it works fine for me. I don’t know if this is the best way of doing it, but seems pretty straightforward and like I said, works:

SELECT * FROM test WHERE timestamp < date('now', '-2 days')
