I have implemented a simple application in Hibernate-4. This application retrieve the value from a table. But when I try to get the record with this
(Booking) session.get(Booking.class, 3740456);
it gives me exception
INFO: HHH000327: Error performing load command : org.hibernate.exception.SQLGrammarException: could not extract ResultSet
So, to verify into the database regarding table and column name, I copy the query from the log statement and execute it. It gives me proper output.
I checked several questions & answers related to this question, but could able to derive the solution.

Is your database configured with case sensitive columns? That could be one reason why Oracle is throwing an "invalid identifier" error
Check your table creating script.
Why is site_an in lowercase in the select such as booking0_.site_an as site_an10_0_0_ while all other column names are in uppercase. I think it may be an uppercase "i" issue.
select
booking0_.id as id1_0_0_,
booking0_.EVENT_DETAIL_ID as EVENT_DETAIL_ID2_0_0_,
booking0_.EVENT_ID as EVENT_ID3_0_0_,
booking0_.PARTNER_C as PARTNER_C4_0_0_,
booking0_.EDI_RECIPIENT_AN as EDI_RECIPIENT_AN5_0_0_,
booking0_.RECORD_SEQUENCE_ID as RECORD_SEQUENCE_ID6_0_0_,
booking0_.RECORD_TYPE_N as RECORD_TYPE_N7_0_0_,
booking0_.EDI_SENDER_AN as EDI_SENDER_AN8_0_0_,
booking0_.SENDER_SEQUENCE_AN as SENDER_SEQUENCE_AN9_0_0_,
booking0_.site_an as site_an10_0_0_

Can someone please help me see where I am going wrong.
I found the solution.
HQL I used is:
Query query = session.createQuery("from Users");
Instead It will be
Query query = session.createQuery("from com.base.test.Users");
That is we have to give to give fully qualified path of the Entity, along with it. This is irrespective of the location of the file where it is used. That is the file inwhere it is used can be in a different/same package as the Entity object.
Same Problem is there when we use #NamedQueries. So below is wrong:
#NamedQueries({
#NamedQuery(
name = "findUsers",
query = "from Users "
)
})
Below is correct:
#NamedQueries({
#NamedQuery(
name = "findUsers",
query = "from com.base.test.Users "
)
})

it was working fine with the 10g dialect and everything,,
please also help me with generating id..i cant generate id in oracle?
now i just hardcoded them just to make it work..
DiscriminatorColumn is supposed to be name of the column. And in your case the name is "vehicle d type". And it's not allowed to use space in name of column.
So use some reasonable name for DiscriminatorColumn. Note that this column must exist in SQL table.
Also note that for the inherited classes you need to specify #DiscriminatorValue("class-specific-value") so hibernate can distinguish which class it actually is.
I'm a beginner in Hibernate Annotation and I'd like to implement an example but it gives me the following error message :

The cause is clearly mentioned:
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near 'group, name) values (null, 'zakaria')' at line 1
Your entity contains an attribute that contribute to this issue:
#Column
private Integer group;
The answer is simple group is a reserved SQL keyword (see GROUP BY clause`)
To resolve this, you need to rename to column name and map it correctly to your entity attribute.
Also, you are not populating the group field, hence it's NULL. Perhaps MySQL doesn't accept NULL for this column?
I hope this helps.
If you want to use the reserved keyword, you can do it using the following specification:
In JPA 2.0:
#Column(name="\"group\"")
In Hibernate:
#Column(name="'group'")
Reference.
To work you have to set the group property or allow it to be null ( nullable=true)
