Juliano Medeiros commented on NIFI-8043:
----------------------------------------
Sorry my images were ignored.
Could you explain the “The key column names don't get quoted in
PutDatabaseRecord before passing them to the database adapter to generate an
UPSERT statement.”
I’m stuck here
Thank you

> h2. First attempt with camel case (fails when translate field name is true or
> false)
> Given that "Quote Column Identifiers" is enabled, one would expect the column
> names inside the conflict clause be quoted as well. However, they didn't seem
> to have been quoted, because my table's column names contain upper and
> lowercases and the flowfile is routed to the failure relationship of the
> PutDatabaseRecord processor with the DB error: {{ERROR: column "camelcase"
> does not exist}}.
> Whether setting "Update Keys" or not did not affect the outcome. If I
> understand, "Update Keys" would also affect the conflict clause, but it's
> also not quoted, and does not accept a string with manually quoted column
> names.
> SQL in question found in the DB error in the log, simplified from what I saw.
> {{INSERT INTO "public"."my_table"("camelCase", "txt")}}
> {{VALUES ("test", "test")}}
> {{ON CONFLICT (CAMELCASE)}}
> {{DO UPDATE SET ("camelCase", "txt") = (}}
> {{ EXCLUDED."camelCase",}}
> {{ EXCLUDED."txt"}}
> {{)}}
> h2. Second attempt with snake case (fails when translate field name is true)
> I changed my column names to {{_snake_case, txt}} and try upserting again and
> it still failed with this SQL in nifi-app.log:
> {{INSERT INTO "public"."my_table"("_snake_case", "txt")}}
> {{VALUES ("test", "test")}}
> {{ON CONFLICT (SNAKECASE)}}
> {{DO UPDATE SET ("}}{{_snake_case}}{{", "txt") = (}}
> {{ EXCLUDED."}}{{_snake_case}}{{",}}
> {{ EXCLUDED."txt"}}
> {{)}}
>
> h2. Current workaround
> I currently need to *disable translate field name* and set my table to *use
> snake case names as column names* to be able to use upsert
