在SQL中获得正确的括号错误

Question

I am getting an error that says I am missing right parenthesis, but I'm not. I dont understand what is going wrong with my query.

CREATE VIEW HB_INV(Book Title, Publisher Name, Price, Units On Hand) AS
SELECT BOOK.TITLE, PUBLISHER.PUBLISHER_CODE||'-'||PUBLISHER.PUBLISHER_NAME,
BOOK.PRICE, INVENTORY.ON_HAND
FROM BOOK, PUBLISHER, INVENTORY
WHERE BOOK.PUBLISHER_CODE = PUBLISHER.PUBLISHER_CODE
AND BOOK.BOOK_CODE = INVENTORY.BOOK_CODE;

Answer 1

The problem is Units on Hand. Make it all one word.

Edit starts here

Actually, it's also "Book Title" and "Publisher Name". Make all the fields in your view single words.

Answer 2

如果这是SQL Server，则需要在[现有单位]周围加上方括号；此外，如果这是发布者代码的串联，请使用'+'代替'||'
