VIEW-TRANSFER-PARAMETERS-1

VIEW_PARAM 视图传参案例

思路：定义一个程序包，然后在视图 以及在查询视图时，分别使用 get set 方法来实现视图的传参。

CREATE OR REPLACE VIEW TEST AS 
SELECT * FROM
(SELECT '1' ID,'AAA' VALUE FROM DUAL
UNION 
SELECT '2','BBB' FROM DUAL
UNION 
SELECT '3','CCC' FROM DUAL)
WHERE ID = P_VIEW_PARAM.get_paramStr1();

查询方式

SELECT * FROM TEST WHERE P_VIEW_PARAM.set_paramStr1('1')='1'
