Обсуждение: Merge statement
Hello Experts,
I have a script to do merging if the two tables' information are match and if not then do the update. I don't know what I did wrong, would you please help out?

There is no MERGE in Postgres.
Is this migrated from Oracle?

yes, this is to migrate from Oracle to Postgres. I followed this link and as same as ora2pg

There is no transaction processing with in a Postgres function until you get to Postgres 11.
You can run a merge in Postgres directly through sql.

Postgres has had stored functions for ages, but only added stored procedures in version 11. Historically, you'll see people calling stored functions in Postgres "stored procedures" as that's what other folks call them. It didn't matter because Postgres only had the one thing. For what's new in Postgres 11 stored procedures, here's a place to look:
The change you're referring to is that a stored procedure (but not a function) has the ability to manage its own transaction blocks.
I actually have no clue...I've only read about the new stored procedures. But if you're coming from Oracle, you're likely looking for PG 11 stored procedures, at least some of the time.
Thank you all. Will look into it on Monday.
Have a pleasant weekend.

I know that it is a procedure and not a function,

good morning, happy Monday.
fyi, I upgraded postgres in AWS to 11.1 and the merge function for procedure is still not working. Still complained the same error that:

As others have said, MERGE is not a command in Postgres. The document you linked is a development document from a long time ago when it was proposed at one time, but it was never accepted. Please reference the actual PostgreSQL documentation.
If you need UPSERT like behavior, look at the INSERT ... ON CONFLICT statement.
Yes, I heard MERGE is not a command in Postgres but the others said merge statement added stored procedures in version 11
I upgraded my postgresql from 10.6 to 11.1. in AWS, still not work.
thank you,

You misunderstood.
Postrgesql added stored procedures in version 11. Unlike stored functions (which PG has had forever), stored procedures allow transactions within their code. This is similar to the stored procedures in Oracle and it helps with Oracle -> Postgresql conversions.
However, Postgresql does NOT and never did have a MERGE command. The "documentation" page you discovered was just a proposal for an implementation that never happened.
Postgresql can detect conflicts on INSERT and perform an UPDATE instead (see https://www.postgresql.org/docs/current/sql-insert.html). This is not exactly the same as Oracle's MERGE so you'll have to study it carefully to make you understand the nuances and be sure it works as intended in your application ... but it is the closest you can get using Postgresql.

Thank you for clarification.
I perform "insert" a new row into a table is the union is not matched and "update" the row when it matched, the script compilation fine.
thank you all again.
