介于两者之间不适用于多个 AND - MYSQL

Question

SELECT price from items Where categoryId = 11724 AND price BETWEEN 10 AND 20

结果：
价格
17.99
18.95
20.0
17.99
18.95

以上查询工作正常，但添加另一个子句未显示所需结果

SELECT price from items
Where categoryId = 11724
    AND ( brand = 'Akaso' OR brand = 'Andoer')
    and price BETWEEN 10 AND 20

Result: 0 rows found

SELECT price from items
Where categoryId = 11724
    AND brand = 'Akaso' OR brand = 'Andoer'
    and price BETWEEN 10 AND 20

结果：
价格
17.99
78.95
77.0
80.99
102.95

已尝试为每个子句使用 and (column and column)。 price 类型是 VARCHAR
CHANGED TO Decimal(10,2) 我哪里做错了？

Answer 1

我没有你的数据，但我觉得一切正常，你的最后一个查询正在尝试这样做：

SELECT price from items
Where (categoryId = 11724
AND brand = 'Akaso') OR (brand = 'Andoer'
and price BETWEEN 10 AND 20)

Answer 2

感谢大家的回复。在将 VARCHAR 类型更改为 Decimal 后，这对我有用：

SELECT price,categoryId,brand from items 
Where categoryId = 11724 
and (brand = 'Akaso' OR brand = 'Andoer') 
and (price BETWEEN 40 AND 50)

SELECT price,categoryId,brand from items 
Where (categoryId = 11724)
and (brand = 'Akaso' OR brand = 'Andoer') 
and (price BETWEEN 40 AND 50)

SELECT price,categoryId,brand from items 
Where categoryId = 11724 
and (brand = 'Akaso' OR brand = 'Andoer') 
and price BETWEEN 40 AND 50

以下无效：

SELECT price,categoryId,brand from items 
Where categoryId = 11724 
and brand = 'Akaso' OR brand = 'Andoer' 
and (price BETWEEN 40 AND 50)

想知道第三个和第四个查询之间的区别。

In between doesn't work with multiple AND's - MYSQL
