SQL / JPA "conditional" uniqueness a thing?
I have a OneToMany Relation Ship in my entities. There is a entity article an a entity draft. Every draft has a unique version in connected with an article.
aritcle_id | draft_id | version ------------------------------- 1 | 1 | 1 1 | 2 | 2 1 | 3 | 3 2 | 4 | 1
If I make the version 'unique' it is version-row-far unique is it possible to declare it article-row-far unique? So you can have duplicated versions but only if the version is attached to another article?
Postgresql error: column must appear in the GROUP BY clause or be used in an aggregate function
Message table from where i want to get recent contacts for 'user1', now the table looks like this:
| id | receiver | sender | time | |----|----------|--------|------------| | 1 | user1 | host1 | 2020-07-02 | | 2 | host2 | user1 | 2020-07-03 | | 3 | user3 | host3 | 2020-07-04 |
I managed to get the expected result by using mysql:
SELECT CASE WHEN receiver = 'user1' THEN sender ELSE receiver END AS id, max(time) AS time FROM message WHERE receiver = 'user1' OR sender = 'user1' GROUP BY CASE WHEN receiver = 'user1' THEN sender ELSE receiver END;
But when i run this query on postgres i get the error: Postgresql error: column receiver must appear in the GROUP BY clause or be used in an aggregate function. Any solution to fix this problem?

Avoid custom cursor to disappear when reaching border of window
I'm having a custom cursor (an svg arrow) in my page. The problem comes when I reach the border of the browser/window with the limit of the image; it disappears and turns into a default cursor pointer.
Is there a way I can avoid the cursor to break/disappear when doing that?
