我试图使用hibernate本机sql(createsqlQuery)语句删除临时表.
这是代码：

session.createsqlQuery("DROP TABLE tmp_dummy_table").executeUpdate();

但它会让我失望：

sql Error: 1003,sqlState: 24000
ORA-01003: no statement parsed

Exception while creating tmp_dummy_table tableorg.hibernate.exception.GenericJDBCException: org.hibernate.exception.GenericJDBCException:could not execute query

        at org.hibernate.impl.sqlQueryImpl.list(sqlQueryImpl.java:152) ....

你能否在这段代码中说明什么错误？
