When using with in relational queries the `orderBy` function is not typed.
I'm trying to query with relational queries and I've made sure to define the relations correctly.
The types work for when I'm selecting columns.
I also can't see the
where
to filter the table.14 Replies
And this is the error when I hover over the
orderBy
:Try
orderBy: (plant, { desc }) => desc(plant.name),
You have it as
orderBy()
but its not a function, see here https://orm.drizzle.team/docs/rqb#order-byRelational queries – DrizzleORM

Both of these are function so it shouldn't make a difference... they just have different syntax.
@mast1999 did you try the approach shown in the docs?
Yep
It still errors.
It won't work because plant is a single entity and not array of those
At least I think so
I had the same issue with filtering relations
@mast1999 whats the error if you use "orderBy: (plant, { desc }) => desc(plant.name)," ?
Anything besides
with
, extras
and colums
won't work on relations that are a single-entity thingy in my experience
¯\_(ツ)_/¯Yeah, I heard that they removed it to help the typescript perf.
we didn't remove them, they weren't present from the start. It's a
one
relation, which always returns either zero on one item, so there is nothing to filter.
- but what if I want to filter the result by a column from a plant
relation?
- you cannot, we don't support filtering by nested columns. If it was a many
relation, you could've added where
on its level and filter the nested array items, but you cannot filter the outer items by a nested relation's field.
so, for example, if you have a users -> cities many-to-one relationship, you can query all the cities with all users and apply filters to either cities, users or both, but you can't filter the list of cities by a user's field. You can filter cities by a city's field and users by a user's field.
the easiest workaround here would be to filter the resulting set in the code after you receive it from the DB.Got it.
Thanks for the clarifications!
If this isn't pointed out anywhere in the docs I think we should point this out.
Others might make the same mistake.
yes, the relations section will be massively reworked
Hi. Just wanted to share an easy workaround using the
sql
operator while we wait for the rework!
Suppose we have two entities. Order
and each order has many Product
s related. Let's say i want to sort all orders by their first product's name (You can also do aggregations, and other stuff but im gonna go with this for the sake of the example).
The code would look something like this for PostgreSQL:
Note: There's an important DB performance issue here, since we're using a correlated query. In case this workaround does not work for you, please consider using a custom sql
query until the team finishes the rework!
