Daniel Cheung updated NIFI-8043:
--------------------------------
Description:
h2. First Attempt with camel case
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
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"}}
{{)}}
