Doobie is "just" a wrapper around JDBC which provides security against SQL injections. So, how would you query raw SQL to get the data you want? Maybe with something like this (just an example, I haven't checked it):

PostgreSQL: jdbc, functions and autocommit

Asked 2021-Jun-11 at 12:32

I've got a PL/pgSQL function and I'm connecting to Postgres 12.x using Scala library called doobie which uses JDBC underneath. I'd like to understand if the whole call to the function will be treated as a single transaction? I've got default setting of autocommit.

The call to the function is simply:

select * from next_work_item();

You have defined a Meta for type Json, but it looks like you're using an instance of UserInfo in the interpolated string. Try converting the object to Json and passing it to sql:

ANSWER

Answered 2021-May-14 at 06:09

It seems that Quill does not escape keyword-like column names, so "order" (and other keywords) columns in it's query will always fail. See Escaping keyword-like column names in Postgres . The workaround is to rename the column in table (and corresponding case classes).

ANSWER

Answered 2021-Apr-28 at 11:14

You can chain together multiple inserts for the same foreign key. I.e. if you have a List of "infos" for every "name", you can traverse over that list to give you back a ConnectionIO[List[_]]. Or just a ConnectionIO[Unit] if you use traverse_.

Sounds like you are looking for [updateMany][1] tho there are times when that just doesn't work.

If you are trying to make the code you have work, you need to apply transact to the IO
