Hibernate: column does not exist

Question

When I try to load an Entity with Hibernate I get the following error in postgres-log:

ERROR: column appuser0_.device_token does not exist at character 35
STATEMENT:  select appuser0_.id as id1_27_0_, appuser0_.device_token as device_t2_27_0_,....

The column device_token definitely exists - and if I copy-paste the whole logged statement and execute it in PGAdmin, I get the expected result.

So what do I forget? What is the difference between the Hibernate statement and the manually executed one?

Depending on how you defined the query, the problem might be located somewhere else: For example, HQL Queries are using the "property-names" of the class, not the column names.

And if you have something like:

@Column("device_token")
private String deviceToken;

Then your HQL-Query should target "deviceToken" and not "device_token". We also encountered a similar error once: Hibernate was reporting "user_id" is missing, because we named the property "userId" with the underscored version for the column name only.

This might be not the problem for you but worth double checking it.
