thank you for replying, if there's no Merge stating in Postgres, what statement in Postgres should I use? Update? I found merge examples on https://wiki.postgresql.org/wiki/MergeTestExamples and the syntax is about the same as Oracle but a function is not working. If I used update syntax it would long implement for this query. I'm not a developer and I'm new to Postgres. Is there a good document you suggest me to use?
thank you again. Bach-Nga

It will fail, of course, since there's no MERGE statement in Postgres.
I think the reason for the weird error is that the plpgsql scanner is
seeing the "INTO cidrdba.sc_date_in" part and trying to process that
as an "INTO plpgsql-variable" clause, before it's fed the rest of the
statement to the core parser, which is what would notice that MERGE
isn't a known command. Maybe we could improve matters by reordering
that processing, but it might be a lot of work for a small benefit.
