Here is my schema:

```sql
CREATE TABLE article_to_warehouse (
  article_id   INTEGER
, warehouse_id INTEGER
)
;
```

How do I add a `UNIQUE` constraint?

In December, a lot of people make plans and ask about what you want for the next year. But a year is a long time, and maybe it's not a good idea to have a rigid plan for such an extended timeframe.

Rigid plans lead to frustration when, inevitably, circumstances force us to change our perspective to varying degrees. Dreams are put on hold, objectives shift and adapt.

So I am not asking about the entirety of 2023. I'm asking instead: what do you hope to achieve in the first semester of 2023?.

As usual, anything goes. Big or small, personal or professional. Whatever you want to accomplish is good for this thread.

I'm curious to learn what's on your mind. Cheers! ;)

What were your highlights for the year? What were the best things you watched? What surprised you? What let you down?

Reflect back on the year and talk about anything and everything related to the movies you watched in 2022. You do NOT have to limit it to 2022 releases -- anything you watched this year counts.

I usually browse Tildes logged out, however today I decided to log in to participate. Before doing so, I wanted to explore Tildes' user interface a little. I opened the "Invite Users" page and was greeted with a message stating: "You aren't able to generate more invite links right now.".

To the best of my knowledge, I have never invited anyone before. I have a strong, random password on my Tildes account so I believe it to be unlikely I was compromised.

Are invites globally disabled, or could a site administrator take a look at my account and check what's going on?
