Hibernate使用sql语句操作数据库时出现的异常could not execute query

Question

代码如下：

HibernateUtil:

public static int createSqlQuery(String sql,
Serializable... serializables) {
Session session = null;
Integer result = null;
try {
session = getSession();
session.beginTransaction();
Query query = session.createSQLQuery(sql);
if (serializables != null) {
for (int i = 0; i < serializables.length; i++) {
query.setParameter(i, serializables[i]);
}
}
result = (Integer) query.uniqueResult();
session.getTransaction().commit();
} catch (HibernateException e) {
if (null != session) {
session.getTransaction().rollback();
}
e.printStackTrace();
}
return result;
}

Test:
public class Test {
public static void main(String[] args) {
String sql = "insert into t_user values(2,'Nero','123','18628840518','[e-mail]')";
System.out.println(HibernateUtil.createSqlQuery(sql));
}
}
