MySQL Query无法获得准确的输出

Question

我有三个类别＆amp;表中的子类别。 类别（冒险，复兴，美食）和sub_category（空气，气球等）

现在我在查询

下面开火了

select * from products where sub_category Like '%Air%' or 
sub_category Like '%Land%' and category = 'adventure' 
and type = 'experience' and status = 'active'

现在问题是它还获得了category = Rejuvenation的行。因此它应该只得到category = adventure

的结果

Answer 1

您必须使用括号或声明：

select * from products where (sub_category Like '%Air%' or 
sub_category Like '%Land%' )and category = 'adventure' 
and type = 'experience' and status = 'active'

Answer 2

AND优先于OR。这就是为什么你的查询返回所有东西，它有像Air这样的子类别。您应该像这样更新您的查询：

select * from products where (sub_category Like '%Air%' or 
sub_category Like '%Land%') and category = 'adventure' 
and type = 'experience' and status = 'active'
