当我将产品添加到 woocommerce 4.4.1 时出现错误消息

Question

当我尝试将产品添加到 wordpresss -> woocomerce 时，出现错误消息：

WordPress 数据库错误：[您的 SQL 语法有误；检查与您的 MySQL 服务器版本相对应的手册，以在 ') OR p.product_id = 30582 OR g.apply_to = 'all' GROUP BY g.id ORDER BY g' 附近使用正确的语法在第 5 行]

SELECT 
    g.*
    , GROUP_CONCAT(DISTINCT c.category_id) as `categories`
    , GROUP_CONCAT(DISTINCT p.product_id) as `products` 
FROM wpav_za_groups as g 
    LEFT JOIN wpav_za_categories_to_groups as c ON c.group_id = g.id 
    LEFT JOIN wpav_za_products_to_groups as p ON p.group_id = g.id 
WHERE 
    c.category_id IN () 
    OR p.product_id = 30582 
    OR g.apply_to = 'all' 
GROUP BY g.id 
ORDER BY g.priority ASC

你能帮忙看看是什么问题吗？

Answer 1

您在 IN 子句中缺少文本或数据

c.category_id IN ('test1','teswt2') 

您必须输入自己的文本或数据，而不是 text1 和 test2

SELECT 
    g.*
    , GROUP_CONCAT(DISTINCT c.category_id) as `categories`
    , GROUP_CONCAT(DISTINCT p.product_id) as `products` 
FROM wpav_za_groups as g 
    LEFT JOIN wpav_za_categories_to_groups as c ON c.group_id = g.id 
    LEFT JOIN wpav_za_products_to_groups as p ON p.group_id = g.id 
WHERE 
    c.category_id IN ('test1','teswt2') 
    OR p.product_id = 30582 
    OR g.apply_to = 'all' 
GROUP BY g.id 
ORDER BY g.priority ASC
