Cannot reference attached DuckDB databases in sources.yml

[Phil-T1]

Hi,

I appreciate that this is probably something that I am missing, but I cannot see how it is possible to reference an attached DuckDB db in sources.yml?

profiles.yml:

attach:
  -path: "./attached_database.db"

I can successfully select from the attached database using the below without Jinja (double quotes must be included here):
SELECT * FROM "attached_database"."attached_table"

However, if I use the following in sources.yml:

  - name: attached_source
    database: attached_database
    tables:
      - name: attached_table

Then
SELECT * FROM {{ source('attached_source', 'attached_table') }}
Compiles to and fails:
SELECT * FROM "attached_source"."attached_database"."attached_table"

If I leave the database part out in sources.yml and use schema:

  - name: attached_source
    schema: attached_database
    tables:
      - name: attached_table

Then
SELECT * FROM {{ source('attached_source', 'attached_table') }}
Of course it compiles to (and fails):
SELECT * FROM "main"."attached_database"."attached_table"

How do I correctly set sources.yml or correctly reference sources.yml to have a select compile to "attached_database"."attached_table"?

Thanks!

Phil.

You need to use both the "database" and the "schema" properties-- I'm assuming what you want is:

- name: attached_source
   database: attached_database
   schema: main

(If that doesn't work-- i.e., it does not then compile to "attached_database.main.attached_table", it's likely a bug)

Thanks for the speedy response again Josh, much appreciated :)

I couldn't get it to work with your solution, but once you told me I should be aiming for compilation to:
"attached_database"."main"."attached_table"
then I managed to get it to work using:

sources:

  - name: attached_database
    schema: main
    database: attached_database
    tables:
      - name: attached_table

I had to try quite a few permutations to get this to succeed, is it worth updating the docs to give an example?

Thanks again,

Phil.

Ah gotcha— yeah, the list of tables in the source is a key part of the config. An example for the README would be most welcome!
