>          Issue Type: Bug
>          Components: query-sql
>    Affects Versions: 3.2.0 cr1
>         Environment: MySQL 4.1.16 Hibernate 3.2 cr1 Fedora Core 4
>            Reporter: Igor A Tarasov

> Quotes must be appied to fields in queries.
> The environment log is:
> org.hibernate.cfg.Environment Hibernate 3.2 cr1
> org.hibernate.cfg.SettingsFactory RDBMS: MySQL, version: 4.1.16 
> org.hibernate.cfg.SettingsFactory JDBC driver: MySQL-AB JDBC Driver, version: mysql-connector-java-3.1.12
> org.hibernate.dialect.Dialect Using dialect: org.hibernate.dialect.MySQLDialect
> I have an entity, named Group:
> @Entity
> public class Group {
>   ..
> }
> But, 'GROUP' is the reserved word of MySQL query language. 
> Log of hibernate show, that queries is without quotes:
> org.hibernate.persister.entity.AbstractEntityPersister Static SQL for entity: org.dicr.isp.entity.Group 
> org.hibernate.persister.entity.AbstractEntityPersister  Version select: select id from Group where id =? 
> org.hibernate.persister.entity.AbstractEntityPersister  Snapshot select: select group_.id, group_.name as name0_, group_.comment as comment0_ from Group group_ where group_.id=? 
> org.hibernate.persister.entity.AbstractEntityPersister  Insert 0: insert into Group (name, comment, id) values (?, ?, ?) 
> org.hibernate.persister.entity.AbstractEntityPersister  Update 0: update Group set name=?, comment=? where id=? 
> org.hibernate.persister.entity.AbstractEntityPersister  Delete 0: delete from Group where id=? 
> org.hibernate.persister.entity.AbstractEntityPersister  Identity insert: insert into Group (name, comment) values (?, ?) 
> And this make a critical error in program logic:
> org.hibernate.tool.hbm2ddl.DatabaseMetadata table not found: Group 
> ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate Unsuccessful: create table Group (id bigint not null auto_increment, name varchar(255) not null unique, comment varchar(255), primary key (id)) 
> ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate 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 (id bigint not null auto_increment, name varchar(255) not null unique, com' at line 1 
> [2006-04-27 23:57:23,895] INFO  org.hibernate.tool.hbm2ddl.SchemaUpdate schema update complete 
> The query: "create table Group (id bigint  ..." is not correct.
> Must be:    "create table `Group` (`id` bigint ..."
