我希望你期望用上面的查询编写简单的程序。所以我用你的SQL查询创建了如下过程。
程序将创建。但是没有使用这个程序。

Create procedure p(parenteqName  Varchar2(30),
                               StartDate          Date,
                               EndDate            Date,
                               Type                   Varchar2(10))

V_IQ                              Number(10);
V_ PARENT_EQ_NAME1 varchar2(30);
V_ REASON_NAME        varchar2(30);

Begin

SELECT    IQ, PARENT_EQ_NAME1, REASON_NAME  into V_IQ , V_ PARENT_EQ_NAME1, V_ REASON_NAME FROM (
SELECT     SUM(IQ) AS IQ, PARENT_EQ_NAME1, REASON_NAME1 AS REASON_NAME FROM

SELECT     REASON_NAME, IQ, PARENT_EQ_NAME1, rank1, 
                                                                      CASE WHEN rank1 > 5 THEN 'SUM OF REMAINING' ELSE REASON_NAME END REASON_NAME1
FROM (

SELECT     REASON_NAME, IQ, PARENT_EQ_NAME1, RANK() OVER(PARTITION BY PARENT_EQ_NAME1
                                                                       ORDER BY IQ DESC) AS rank1

)))
GROUP BY PARENT_EQ_NAME1, REASON_NAME1

union all

Exception
When others then
Null;
End;

最好在这里提问之前先谷歌。
