If existing record, row is returned, but if new record inserted, row is not returned

QUESTION

If existing record, row is returned, but if new record inserted, row is not returned

Asked 2018-Dec-23 at 08:09

Two tables. author, and book

I am adding a Book into the book table. If the Author is listed is already in the author table, then get the author's id and insert it into the Book row. If the Author is not in the author table, then insert a new author and use the id to insert into the Book row.

This functionality works fine. The database responds appropriately and with the code below (not the actual code, but a more refined version) and rows are appropriately referenced or created.

I also want the query to return the Book row and this is fine. The Book row is always returned in all tested conditions, be it a Book with an existing author or a Book with a known author.

The issue comes when I now want to join it with the author table to get the author details back as well.

NOW -> If I insert a Book with a known Author, the functionality is perfect and the row is returned perfectly as expected. If I insert a Book with a NEW Author, the new author is still created, the new book is still inserted BUT ZERO rows are returned.

I am not sure why this is happening or how I would go about getting the row.

Explanation

This has to do with the behavior of common table expressions in PostgreSQL.

Per the docs (https://www.postgresql.org/docs/current/queries-with.html):

The sub-statements in WITH are executed concurrently with each other and with the main query. Therefore, when using data-modifying statements in WITH, the order in which the specified updates actually happen is unpredictable. All the statements are executed with the same snapshot (see Chapter 13), so they cannot “see” one another's effects on the target tables. This alleviates the effects of the unpredictability of the actual order of row updates, and means that RETURNING data is the only way to communicate changes between different WITH sub-statements and the main query. An example of this is that in
