MALL FROM和FROM

"MALL FROM"不是一个正确的短语或句子，可能是误拼或语法错误。而"FROM"是一个介词，用于表示起点、出发地或来源。例如：

- I'm from New York.（我来自纽约。）
- The package is from Amazon.（这个包裹来自亚马逊。）
- We drove from San Francisco to Los Angeles.（我们从旧金山开车去洛杉矶。）

update mall_user set team_num = (select * from (select (count(1) + 1) a from mall_user where p_ids like #{likeId}) r), promotion_num = (select * from (select count(1) a from mall_user where p_ids like #{likeId} and is_vip = 1) r), DIRECT_PUSH_NUM = (select * from (select count(1) a from mall_user where p_id = #{id}) r), effective_direct_push_num = (select * from (select count(1) r from mall_user where p_id = #{id} and is_vip = 1) r), one_star_condition = (select * from (select count(1) a from mall_user where p_ids like #{likeId} and USER_LEVEL_ID = '1') r), two_star_condition = (select * from (select count(1) a from mall_user where p_ids like #{likeId} and USER_LEVEL_ID = '2') r), three_star_condition = (select * from (select count(1) a from mall_user where p_ids like #{likeId} and USER_LEVEL_ID = '3') r), four_star_condition = (select * from (select count(1) a from mall_user where p_ids like #{likeId} and USER_LEVEL_ID = '4') r) where id = #{id} 死锁了怎么办

这是一条SQL语句，用于更新mall_user表中的team_num字段值。具体的更新规则是以当前用户的层级关系为基础，将其下属团队成员数目作为team_num的值。其中，子查询语句(select count(1) 1 from mall_user where p_ids like '当前用户id,%')用于获取当前用户下属成员的数量。需要注意的是，该SQL语句中存在语法错误，在子查询语句的最后缺少一个括号。正确的写法应该是：update mall_user set team_num = (select * from (select (count(1)) a from mall_user where p_ids like '当前用户id,%') b)。

这个错误提示是在加载应用程序配置文件时发生的错误，具体原因可能是以下几种情况之一：

1. 文件路径错误：检查一下文件路径是否正确，确保配置文件存在于指定的路径中。

2. 文件编码格式错误：检查一下文件的编码格式是否正确，常见的编码格式有 UTF-8、GBK 等。

3. 文件格式错误：检查一下文件格式是否正确，比如是否按照 YAML 或者 Properties 的格式书写。

4. 文件访问权限错误：检查一下文件的访问权限是否正确，确保应用程序有足够的访问权限读取文件。

如果以上方法都无法解决问题，建议您检查一下应用程序的配置文件是否正确，并且检查一下应用程序的启动日志，查看是否有其他异常信息。
