sql - MYSQL语句语法错误

Question

我快要被这个愚蠢的 mysql 语句弄丢了。谁能告诉我这个声明有什么问题吗？

SELECT * FROM contacts 
INNER JOIN ind_categories ON contacts.vendor_id = ind_categories.vendor_id AND ind_categories.category_id = "retail" 
AND WHERE zipcode in ( " 93044,93041,93043 " )

Answer 1

尝试:

SELECT * FROM contacts INNER JOIN ind_categories ON contacts.vendor_id = ind_categories.vendor_id AND ind_categories.category_id = 'retail' WHERE zipcode in 
('93044','93041','93043')

您的 WHERE 之前不应该有 AND，IN 子句中的每个 set 元素都需要单独引用(如果它是文本列，或者如果它是数字列则根本不引用)，并且您的引号必须是单引号.
