為了在 Hibernate 中使用存儲過程，你必須遵循一些規則。不遵循這些規則的存儲過程將不可用。如果你仍然想使用他們，你必須通過 session.connection() 來執行他們。這些規則針對于不同的數據庫。因為數據庫提供商有各種不同的存儲過程語法和語義。
對存儲過程進行的查詢無法使用 setFirstResult()/setMaxResults() 進行分頁。
建議采用的調用方式是標準 SQL92: { ? = call functionName(<parameters>) } 或者 { ? = call procedureName(<parameters>) }。原生調用語法不被支持。
對于 Oracle 有如下規則：
對于 Sybase 或者 MS SQL server 有如下規則：

Hibernate: {call getUserList()}

hibernate提供了在*.hbm.xml中配置調用存儲過程，并通過向用戶提供session.getNamedQuery(“…”)方法來調用配置的調用查詢相關的存儲過程的方法 ，另外，hibernate還提供了取得sql的connection的方法，從而能夠通過connection中存儲過程調用相關的方法來實現存儲過程的調用。
