oracle - 存储过程来比较 2 个字段并在另一个表中返回不匹配

Question

我在 Oracle SQL Developer 中创建存储过程。我正在尝试比较 2 个表的两列，如果任何表有更多记录，我需要收集它们并将其存储在（另一个表）中投掷

ORA-01422：精确提取返回超过请求的行数 ORA-06512：在“TEST_VAL”，第 73 行 ORA-06512：在第 2 行

如果我将其作为 SQL 查询运行，这是运行良好的查询

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

我的存储过程看起来像这样

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;

任何帮助都会得到帮助
