How to tell Hibernate annotation #Column to be case-sensitive?

I'm trying to do a simple SELECT query in a table named ECM (in uppercase) on a Sybase db with Hibernate. I've annotated my DBO this way :
#Entity
#Table(name="ECM")
public class RelationshipDbo {
...
}
However, I'm facing a "table not found" error : the generated SQL has the table name in lowercase. I cannot change the database configuration to tell it to be case-insensitive.
I've also tried putting quotes like this :
#Table(name="`ECM`")
and this :
#Table(name="'ECM'")
Result : the quotes are added in the query, but the table name is still converted from uppercase to lowercase.
Technical information :
Hibernate 4.3
JPA 1.2
org.hibernate.dialect.SybaseDialect
Have you guys any idea?
EDIT: Also tried this Hibernate changes #Table(name) to lowercase
Then my columns names and table name are automatically quoted, but the names still get lowercased.

I think I have your answer:
Basically, you need to change the naming strategy for you JPA provider. How you do this will depend on how you setup your project.
In my case, using spring boot data I set a property in my application.properties to
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.EJB3NamingStrategy
Without more details from you I can't give more specifics on how to do this.

My goal is a little different since was trying to create tables upper case and hibernate created them in lower case. Also i was using MySQL not Sybase.
But for me quoting the names like this worked:
#Entity
#Table(name="\"ECM\"")
public class RelationshipDbo {
...
}
Then tables were created upper case. Maybe that helps also for the queries.

What is your Sybase db version ?
SybaseDialect has been deprecated in Hibernate 3.5 and then refactored since Hibernate 4.1 with a bunch of subclasses matching different versions of Sybase. Have you tried one of the subclasses to see if it makes any difference?
org.hibernate.dialect.Sybase11Dialect
org.hibernate.dialect.SybaseAnywhereDialect
org.hibernate.dialect.SybaseASE15Dialect

Try this:
Use backticks as in #Table(name="`ECM`")?
This must work from Hibernate point. If not then problem should be in DB (if i'm not wrong)

HIBERNATE: Auto append word into TABLE

hi I have an entity with this annotation
#Entity
#Table(name = "REPORT_WORK")
But for some reason hibernate keep saying Missing Table: REPORT_REPORT_WORK
I know that is the problem because of when I change the name to "REPORT_WORKX"
It will say Missing Table: REPORT_REPORT_WORKX
Has any encountered this issue before?
Update: when I change the name to JJJJ
It will say Missing Table: REPORT_JJJJ
so for some reason there it is auto appending REPORT_
Configuration:
hibernate.hbm2ddl.auto=validate

I suspect that the problem is your Hibernate configurations. Specifically, if you don't have an appropriate setting for hibernate.hbm2ddl.auto, Hibernate won't automatically update the database schema when you change your model.
(And if you don't want the updates to happen automatically, then you need to figure out what schema changes are needed, code them as SQL DDL, and run them manually.)

Can you post your persistence.xml (or equivalent)?
It sounds like you are implementing org.hibernate.cfg.NamingStrategy, get rid of this configuration.

How to support support SqlServer's ".." in HyperSQL?

tl;dr: I am trying to unit test some SqlServer queries which state the db name but they do not seem to work in HyperSql.
We are using Sql Server in production and I am trying to use HyperSQL as my database for unit testing. I am trying to test a class that creates SQL queries so stubbing out the database is not an option as having the queries parsed by a real database is part of the test.
Queries are supposed to be created in the form of SELECT * FROM EntAsdfDb007..Data_Table, although we can use the schema name ( 'db' ) if we wish.
From what I understand about the SELECT format for SqlServer, it allows you to specify the name of database followed by the name of schema. Also, you can drop the name of the database and have it inferred.
In HyperSqlDb I have been able to create the schema 'db' and create the necessary tables within it, and have been able to create tables within that schema but I have not be able to query with the database name even after setting the DB name using .setDatabaseName(). The exception I get is:
Caused by: org.hsqldb.HsqlException: user lacks privilege or object not found: ENTASDFDB007
Just to be clear: I am unit-testing a class that uses SQL like SELECT * FROM EntAsdfDb007..Data_Table. I am trying to set up an instance of HyperSql for unit testing purposes but HyperSql seems to reject the syntax used.

That won't be possible.
HyperSQL cannot be changed to accept non-standard naming schemes.

It is possible. HSQLDB does have one catalog per database. The catalog name is PUBLIC by default, which you can change.
ALTER CATALOG PUBLIC RENAME TO EntAsdfDb007
You can then access your table with
SELECT * FROM EntAsdfDb007.db.Data_Table

java hibernate netbeans xml

When i am using net beans to develop one standalone swing application which is transacting with derby database. In my database i dont have any ID field all columns are nullable but when i am mapping my abc.hbm.xml file and validating it is givin following error:-
The content of element type "class" must match "(meta*,subselect?,cache?,synchronize*,comment?,tuplizer*,(id|composite-id),discriminator?,natural-id?,(version|timestamp)?,(property|many-to-one|one-to-one|component|dynamic-component|properties|any|map|set|list|bag|idbag|array|primitive-array),((join,subclass*)|joined-subclass*|union-subclass*),loader?,sql-insert?,sql-update?,sql-delete?,filter*,resultset*,(query|sql-query)*)". [20]
Can anybody help me out with this error.
Cant we map that xml without having ID field in table???

Your XML is invalid, because it doesn't conform to the hibernate DTD. As the error message says, every class element must have either one id sub-element, or one composite-id sub-element.
A hibernate entity must have an ID (simple or composite). Your database schema deosn't seem very clean. You should have a primary key in every table.

Generated queries contain schema and catalog name

I've the same problem as described here
In the generated SQL Informix expects catalog:schema.table but what's actually generated is
catalog.schema.table
which leads to a syntax error.
Setting:
hibernate.default_catalog=
hibernate.default_schema=
had no effect.
I even removed schema and catalog from the table annotation, this caused a different issues : the query looked like that ..table same for setting catalog and schema to an empty string.
Versions
seam 2.1.2
Hibernate Annotations 3.3.1.GA.CP01
Hibernate 3.2.4.sp1.cp08
Hibernate EntityManager 3.3.2.GAhibernate
Jboss 4.3 (similar to 4.2.3)

Note that there is a new (as of 2010-04-26) web page, http://www.iiug.org/opensource, that has information about using Informix software with various open source packages, including Hibernate. In particular, there is downloadable code that improves the interaction of Hibernate and Informix.

I ended up with the one of the worst hacks I evever did:
The colon is the offending char wich should be '.' catalog:schema.table.
Informix allows comments in SQL statements select {comment} * from sometable
So I set
hibernate.default_catalog={
hibernate.default_schema=}schemaname
the resulting code looks like
select * from {.}schemaname.tablename
which is accepted by informix query parser.

Delete the schema and catalog attributes from *.hbm.xml.
