Java EE：org.postgresql.util.PSQLException：列不存在，但存在

Question

While trying to browse to a generated JSF page, the following error occurs. This exact error also occurs when using REST (Jax-RS) to manipulate or retrieve info from the database:

Internal Exception: org.postgresql.util.PSQLException: ERROR: column "transkey" does not exist

However, this column does exist, when executing the exact query that triggers the error from pgAdmin, a normal table is returned (SELECT translationid AS a1, lang AS a2, transkey AS a3, transval AS a4 FROM projectx.projectx.translation)

Full stacktrace:

Very greatful for your answer(s). :)

Answer 1

Just a guess: check if you really have transkey column in database. I see that you have a getter/setter for transkey named getKey()/setKey(), maybe that misled db schema generator?

Answer 2

One question: are you using "transKey" or "transkey" as the name of your dababase's field? The uppercase generated the error in my JPA application.
