He got it right (which makes sense; he coined the term); OP didn't.

I am aware, but the person I'm replying to mentioned a specific device, which I also have.
Where was it? Haven't find it on mine
It says right there in the thumbnail: it's mm-wave radio. They're radios that talk to each other and form a mesh network.
Another satisfied Framework user here, wondering what kind of struggles you've been facing; I haven't had any problems at all.
Sauerkraut is apparently a reasonable way to store vitamin C for a long time. I imagine cabbage in its own doesn't keep too well.
I've only ever seen Chile as the country.
I really didn't think that's correct--though it's been a few years since I did SQL regularly.
SELECT *
FROM articles
WHERE last_updated >= %s
AND created_at IS NOT NULL
UNION
SELECT *
FROM articles
WHERE id IN (1, 2, 3)
AND created_at IS NOT NULL
That should give a list of all articles updated after whatever date (regardless of ID), appended to a list of all articles where the ID is 1, 2, or 3 (regardless of when they were last updated). I would expect to see extra articles that only fit one criteria or the other, and also duplicate articles.
I included the join quote because an inner join would be the way to do this, rather than a union--though it would likely be less efficient than just filtering on the required parameters.
If I'm wrong here, I'd love an explanation of why.
UNION is used to append the result of one query to the result of another: https://learn.microsoft.com/en-us/sql/t-sql/language-elements/set-operators-union-transact-sql?view=sql-server-ver17
A UNION concatenates result sets from two queries. But a UNION does not create individual rows from columns gathered from two tables. A JOIN compares columns from two tables, to create result rows composed of columns from two tables.
Your two queries are not equivalent.
Sure seems to be. I see it advertised here and there pretty often.
This is the opposite of bag holding though, isn't it? Since it's an expanded offering to sell?
