[英]Mysql query doesn't follow condition
So I have the following mysql query, which works but not the right way: 因此,我有以下mysql查询,该查询有效,但方法不正确:
SELECT * FROM (`CriteriaItems`) INNER JOIN `Address` ON `Address`.`address_id` = `CriteriaItems`.`address_id` WHERE `criteria_id` = '2' AND `status` = 'published' AND `mls_id` LIKE '%123%' OR `Address`.`address` LIKE '%123%' LIMIT 10
The problem is that I see it returns results that also have "status" = "deleted" and thats because of ``Address .
问题是我看到它返回的结果也具有“ status” =“ deleted”,这就是因为“ Address”
.
address LIKE '%123%'
if I remove this it works, but I need this. 如果我删除了此地址,则
LIKE '%123%'
,但是我需要它。
So it suposed to search in the address table as well, but only based on CriteriaItems`.`address_id
因此它也想在地址表中进行搜索,但仅基于
CriteriaItems`.`address_id
Its because AND
operator has higher precedence than OR
, right now your query works like this. 这是因为
AND
运算符的优先级比OR
更高,现在您的查询像这样工作。
WHERE `criteria_id` = '2'
AND (`status` = 'published' AND `mls_id` LIKE '%123%')
OR `Address`.`address` LIKE '%123%' LIMIT 10
More information on this can be found here 可以在这里找到更多信息
So you need to use Parenthesis to apply the condition properly 因此,您需要使用括号正确地应用条件
WHERE `criteria_id` = '2'
AND `status` = 'published' AND
(`mls_id` LIKE '%123%' OR `Address`.`address` LIKE '%123%')
LIMIT 10
You need to wrap OR
with bracket: 您需要使用方括号将
OR
换行:
SELECT *
FROM `CriteriaItems`
JOIN `Address`
ON `Address`.`address_id` = `CriteriaItems`.`address_id`
WHERE `criteria_id` = '2'
AND `status` = 'published'
AND (`mls_id` LIKE '%123%' OR `Address`.`address` LIKE '%123%')
LIMIT 10;
Consider also using ORDER BY
to get stable results. 还考虑使用
ORDER BY
获得稳定的结果。
Simple bool logic: 简单的布尔逻辑:
p1 AND p2 AND p3 OR p4 is true <=> (p1 AND p2 AND p3) is true OR p4 is true
I guess you want: 我想你要:
p1 AND p2 AND (p3 OR p4)
