SQL quoted identifiers : Hibernate gives the potability to force to quote an identifier in the generated SQL enclosing the table or column name in backticks in the mapping element. Hibernate will use the correct quotation style for the SQL Dialect. In hibernate this is usually double qotes, but in the SQL server uses brackets and MySQL uses backticks.
Small Example:
<class name="Lion" table="`Item Lion`">
<id name="id" column="`Item Id`"/>
<generator class="assigned"/>
</id>
<property name="itemNumber" column="`Item #`"/> ...
</class>
