我编写了一个SELECT查询来选择特定值，基本上它只选择所有3个表中的数据。
但是当我尝试更新时，它仍然会更新比应该更多的数据（行）
这是选择
SELECT
i.id, i.group_id, i.name, u.item, u.value, u.shows, u.nr, u.type
FROM
items AS i
INNER JOIN
item_groups, item_properties2 AS u ON item_groups.id = i.group_id
WHERE
item_groups.idp = '1140503406'
AND i.id = u.item
AND u.type = 1140614900
LIMIT
30, 3000
这里是UPDATE
UPDATE item_properties2 AS P
INNER JOIN items ON items.id = P.item
INNER JOIN item_groups ON item_groups.idp = '1140503406'
SET P.nr = '0'
WHERE
P.type = 1140614900`
它似乎忽略了我的item_groups.idp ='1140503406'，而是更新其中的所有内容，而不仅仅是此值。我不知道如何理解它只应更新数据，如果它的item_groups.idp ='1140503406'而不是所有item_groups.idp。

将谓词items_groups.idp = '1140503406'移至WHERE子句，使用JOIN条件item_groups.idp = items.group_id代替它，如下所示：
UPDATE item_properties2 AS P
INNER JOIN items ON items.id = P.item
INNER JOIN item_groups ON item_groups.idp = items.group_id
SET P.nr = '0'
WHERE P.type = 1140614900
AND items_groups.idp = '1140503406';
