我正在尝试在Oracle 11g上运行此代码,它在下面给出了错误.我似乎无法做对.
DECLARE
CURSOR bookcursor IS
SELECT btName, BookCopy.Isbn, pubName, dateDestroyed
FROM booktitle bt
JOIN publisher p
ON bt.pubId = p.pubId
JOIN bookcopy bc
ON bt.Isbn = bc.Isbn
WHERE datedestroyed IS NULL
;
bookcursorrec bookcursor%ROWTYPE;
BEGIN
OPEN bookcursor;
LOOP
FETCH bookcursor INTO bookcursorrer;
EXIT WHEN bookcursor%NOTFOUND;
dbms_output.put_line( 'ISBN: ' ||bookcursorrec.isbn
|| ' - Book Name: ' || bookcursorrec.btname
|| ' - Publisher: ' || bookcursorrec.pubname );
END LOOP;
CLOSE bookcursor;
END;

无法获取此语句来更新表,我几乎可以肯定我的问题是串联语法.
请看看,如果你看到我在这里出错了,请告诉我..
