Have WITH statements been deprecated?

When I run:

WITH user_first_video AS (
    SELECT
        userId,
        MIN(DATE(createdAt)) AS first_video_date
    FROM VideoProject
    GROUP BY userId
)

select * from user_first_video

I get:

VT12001: unsupported: WITH expression in SELECT statement

I remember WITH expressions used to be possible in Metabase. Has this been deprecated?

Isn't it a Vitess, and not Metabase, warning ?

Metabase doesn’t parse the sql you write, this is something an error at the database level
