Question

我对此查询有疑问：

SELECT * 
FROM posts 
WHERE title LIKE '%samsung%' 
OR title LIKE '%42%' 
AND price >= '100' 
AND price <= '1000000' 
AND shipping = '1' 
AND sale_type = '1' 
LIMIT 0,50

问题在于，当我使用2个或更多title LIKE '%%'运行查询时，它只向我显示title LIKE '%%'

的查询

SELECT * 
FROM posts 
WHERE title LIKE '%samsung%' 
AND price >= '100' 
AND price <= '1000000' 
AND shipping = '1' 
AND sale_type = '1'
LIMIT 0,50

忽略其他选项。但是，如果我只使用标题LIKE＆＃39; %%＆＃39;运行查询它很完美。

希望有人能帮我一臂之力

Answer 1

使用括号：

SELECT * FROM posts 
WHERE (title LIKE '%samsung%' OR title LIKE '%42%')
    AND price >= '100' 
    AND price <= '1000000' 
    AND shipping = '1' 
    AND sale_type = '1' 
LIMIT 0,50

您的查询应该是

SELECT * FROM posts 
WHERE price >= '100' 
AND price <= '1000000' 
AND shipping = '1' 
AND sale_type = '1'
AND (title LIKE '%samsung%' OR title LIKE '%42%') 
LIMIT 0,50
