### SQL方言 ###

**1、Hibernate JDBC属性**

<table> 
 <thead> 
  <tr> 
   <th>属性名</th> 
   <th>用途</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>hibernate.connection.driver_class</td> 
   <td><em><em>jdbc驱动类</em> </em></td> 
  </tr> 
  <tr> 
   <td>hibernate.connection.url</td> 
   <td><em>jdbc URL</em> </td> 
  </tr>
