存儲過程comapre 2字段並在另一個表中返回mismactch

Question

我正在Oracle SQL Developer中創建存儲過程。我想比較兩列表格2表，如果任何表有更多的記錄，我需要收集它們並將其存儲在（另一個表）我的存儲過程工作正常，如果我只有一個記錄的不匹配，超過一個記錄和它拋出

ORA-01422：精確獲取回報超過行 ORA-06512的請求數：在 「爲test_val」，行73 ORA-06512：在2號線

這裏是運行就好查詢如果我運行它作爲SQL查詢

SELECT h.STATEMENTNUMBER, h.STATEMENTTOTAL 
FROM statement_header h 
MINUS 
SELECT j.STATEMENTNUMBER, j.STATEMENTTOTAL 
FROM jwf_statement j; 

和我的存儲過程是這樣的

create or replace PROCEDURE  TEST_VAL 
IS 
l_num_recs  VARCHAR2 (20); 
BEGIN 
select STATEMENTNUMBER into l_num_recs 
from 
(SELECT H.STATEMENTNUMBER, H.STATEMENTTOTAL 
FROM statement_header H 
MINUS 
SELECT J.STATEMENTNUMBER, J.STATEMENTTOTAL 
FROM jwf_statement J 

); 
insert into l_num_recs values(l_num_recs); 
Commit; 
End; 

任何幫助appriciated
