DB2中簡單存儲過程 selectAllUsers
CREATE procedure selectAllUsers
DYNAMIC RESULT SETS 1
BEGIN
DECLARE temp_cursor1 CURSOR WITH RETURN TO CLIENT FOR
SELECT * FROM test;
OPEN temp_cursor1;
END;
映射文件中關于存儲過程內容如下
<hibernate-mapping package="com.unmi.vo">
<class name="Test" table="TEST">
............
</class>
<sql-query callable="true" name="selectAllUsers">
<return alias="aa" class="Test">
<return-property name="oborqt" column="OBORQT"/>
<return-property name="moorqt" column="MOORQT"/>
<return-property name="roschn" column="ROSCHN"/>
<return-property name="plandate" column="PLANDATE"/>
</return>
{ ? = call selectAllUsers() }
</sql-query>
</hibernate-mapping>
{ ? = call selectAllUsers() } 也可以寫成{ call selectAllUsers() }，
如果有參數就寫成
{ ? = call selectAllUsers(?,?,?) }
代碼中對query設置相應位置上的值就OK
Java調用關鍵代碼如下
Session session = HibernateUtil.currentSession();
Query query = session.getNamedQuery("selectAllUsers");
List list = query.list();
System.out.println(list);
要求你的存儲過程必須能返回記錄集，否則要出錯
如果你的存儲過程是完成非查詢任務就應該在配置文件用以下三個標簽
<sql-insert callable="true">{call createPerson (?, ?)}</sql-insert>
<sql-delete callable="true">{? = call deletePerson (?)}</sql-delete>
<sql-update callable="true">{? = call updatePerson (?, ?)}</sql-update>
