Hi, We are on Phoenix 4.7, so pre-Atomic Upserts that were introduced in 4.9. I am trying to determine if there is a way to achieve similar functionality with UPSERT SELECTs.
However, having read the documentation I'm not clear on the isolation-level that is used when UPSERT SELECTs are executed on the serverside. Can anyone confirm whether both the SELECT and UPSERT elements are performed atomically? And also that updates to an individual row are performed serially? I'm guessing there is no atomicity otherwise the new Atomic Upserts wouldn't exist. Thanks in advance, Owen -- Owen Rees-Hayward 07912 876046 twitter.com/owen4d
