Is there a way to do upserts in PostgreSQL

See original GitHub issue

I’m relying on using INSERT ... ON CONFLICT (internal_id) DO NOTHING or ``INSERT … ON CONFLICT (internal_id) DO UPDATE …` operations. Especially those updates are tedious to write for wider tables (each property name repeated like 5 times…). Is there a way this library could help me?

If the answer is no, but you’d like to have this functionality, I’d be happy to implement that.

MERGE in sql server has issues …… https://sqlperformance.com/2020/09/locking/upsert-anti-pattern

I’d rather say that SQL server is an antipattern… His amazing solution is not that great, since it will only work properly in SERIALIZABLE mode which will lead to even more problems on this joke DBMS (otherwise you might get conflict. The whole point of doing upserts is to get rid of them).

If we have to support Microsoft SQL, I’m definitely not going to implement it. I’ll close this issue, as it does not seem as easy to solve given the constants. Probably best to rely on custom helper functions for a specific use case…

Out of my depth here but just chiming in to say that to my knowledge MSSQL uses the MERGE statement/syntax for upserts. Possible i misunderstand the conversation though.

Looking here because i’m actually attempting to use the library now for such a situation and it’d help to have.
