用户已经具有创建表的权限，hbm2ddl-auot已经设置了update，还是无法生成表

用ORACLE数据库，之前写错了用户，在别的用户下生成了表，然后删除掉了，重新配置了hibernate.cfg.xml，结果就不能生成表了，浏览器总报这个。。。。。 org.hibernate.exception.SQLGrammarException: could not execute query

……………………………………………(此处省略一大堆错误信息) 在数据库中用户权限已经有了，hbm2ddl.auto已经设置了update（尝试着设置成了create，也失败）。。。请问这是怎么回事？
10分	项目启动的时候报错吗
10分	将hbm2ddl-auot已经设置为create试试
	重新启动项目试试看
	我遇到过这个问题，你可以看看我的帖子，我估计你是sql语句的问题，如果你建表，那就是创建的表的时候有哪个变量，也就是参数有问题，建议在oracle用sql语局写下，在对应在代码仔细查查，看看是哪个参数的错，因为仅过了ORM（对象实体映射）也就是hibernate的对jdbc的封装，看不到底层的参数，所以要细心检查。比如，一个update操作，你传的是一个model对像，但是实际上回到底层还是会先where id 然后from 的总之，里面有参数的东西。
	应该是你配置的有点问题在你配置文件中找问题吧
