Sorry that that was your first experience. I have opened an issue for this for you: https://github.com/PRQL/prql/issues/3074

The correct link is the following: https://prql-lang.org/book/project/integrations/prefect.html

TBH, that one is not much of an integration yet. It essentially boils down do.

    $ pip install prql-python

and then

    import prql_python
    PostgresExecute.run(..., query=prql_python.compile(prql))

I don't personally work with Prefect, so if you have any ideas about what you would like to see here, please comment on the issue or on Discord. We're also very open to Pull Requests and they usually get merged fast ;-)

Disclaimer: I'm a PRQL contributor.

Thanks! We just did a big refactoring so we do have some links failing in our tests. Just PR-ed a fix to this one: https://github.com/PRQL/prql/pull/3075
