使用hibernate对oracle数据库分页出现错误

[yaterman2]

代码
public List findRec(final String hql, final int firstResult,
final int maxResults) {
return getHibernateTemplate().executeFind(new HibernateCallback() {
public Object doInHibernate(Session s) throws HibernateException,
SQLException {

Query query = s.createQuery(hql);
query.setFirstResult(firstResult);
query.setMaxResults(maxResults);
List list = query.list();
return list;
}
});
}

public List getRolesCategorys(final int start, final int limit) {
return findRec("from HtSysRolesCategory", start, limit);
｝

输出的hql:
Hibernate: select htsysroles0_.ROLE_CATE_ID as ROLE1_1_, htsysroles0_.ROLE_CATE_NAME as ROLE2_1_ from HT_SYS.HT_SYS_ROLES_CATEGORY htsysroles0_ limit ?
(怎么多出了limit? ，我用的是oracle)

错误：

Struts Problem Report

Struts has detected an unhandled exception:
Messages:

2. could not execute query
3. could not execute query; SQL [select htsysroles0_.ROLE_CATE_ID as ROLE1_1_, htsysroles0_.ROLE_CATE_NAME as ROLE2_1_ from HT_SYS.HT_SYS_ROLES_CATEGORY htsysroles0_]; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query

请高手帮忙啊。

hibernate配置里面的数据库类型配错了。

[牛叔]

配置文件错了
自己检查一下

不应该啊，我将query.setMaxResults(maxResults);行代码去掉就没有错误了啊。

[xianaofei]

底层架包驱动或者配置文件错误了

[bean]

<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>，这是MYSQL的方言吧，改为ORCLE的

[niu90]

<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>改为org.hibernate.dialect.Oracle9Dialect

[yaterman2]

我晕了
