表列如下：
Users表（表名：Users）：
[用户表]
Friends表（表名：Friends）：
“好友表”
我的Sql代码：
SELECT
friend_id,
friend_adding_id,
friend_added_id,
user_id,
user_name
FROM friends
LEFT JOIN users ON friends.friend_added_id = users.user_id
WHERE
friend_adding_id = 1
OR friend_added_id = 1
AND friend_confirm = 1
ORDER BY friends.friend_id DESC
LIMIT 1, 10
留下下面一栏：
“离开栏”
如何修复此缺失的查询？请帮帮我.
首先，您缺少了一行而不是列或者不是查询，其次，这是因为与/或优先级。并且具有比或更高的优先级,要使逻辑正常工作,必须通过使用括号给予或更高的优先级：
SELECT
friend_id,
friend_adding_id,
friend_added_id,
user_id,
user_name
FROM friends
LEFT JOIN users ON friends.friend_added_id = users.user_id
WHERE
(friend_adding_id = 1 OR friend_added_id = 1) -- < like this
AND friend_confirm = 1
ORDER BY friends.friend_id DESC
LIMIT 1, 10
