MySQL 查询返回语法错误

Question

我正在运行这样的查询，但出现错误

insert into oc_product_to_category (product_id, category_id) values (select product_id from oc_product where model='Schar Gluten & Wheat Free Classic White Bread, 14.1 oz (Pack ' and price=36.26 limit 1, select category_id from oc_category_description where name='Bakery & Bread');

我做错了什么？

Answer 1

您不需要带有 insert 的 values 。 。 。选择:

insert into oc_product_to_category (product_id, category_id)
    select (select product_id
            from oc_product
            where model = 'Schar Gluten & Wheat Free Classic White Bread, 14.1 oz (Pack ' and
                  price = 36.26
            limit 1
           ),
           (select category_id
            from oc_category_description
            where name='Bakery & Bread'
           );

但是，您的问题可能是第二个子查询没有用括号括起来。
