org.hibernate.QueryException:Expected positional parameter count: 4
今天順便把之前出現的錯誤也發上來org.hibernate.QueryException:Expected positional parameter count: 4, actual parameters: [] [from LhClient c where c.wnamw=?]
Query query=session.createQuery("from LhClient c where c.wnamw=?");
query.setString(0, wxy);
在hql語句中有一個佔位符“?”,則在query.setParameter()處,一定要有一個相對用的位被傳入,否則會出現上述異常。。哈哈,希望對大家有幫助 ..
