insert语句在pl/sql中替换数据可以执行，但是java中却报错

java语句：
public int initiating(String title, String content, String numberLimit,String fkCustomerId) {
String pkId = "44";
String sql="insert into ACTIVITY_INFO (pk_id,title,content,fk_customer_id,number_limit,create_date) values(:pkId,:title,:content,:fkCustomerId,:numberLimit,sysdate)";
Query query = this.getSession().createQuery(sql);
query.setParameter("pkId", pkId);
query.setParameter("title", title);
query.setParameter("content", content);
query.setParameter("fkCustomerId", fkCustomerId);
query.setParameter("numberLimit", numberLimit);
int num = query.executeUpdate();
return num;
}
报错信息：
