MySQL function when used with the rear bracket can not root spaces between

修改前代码：
select MAX (article_order)
from mall_school_article
where 1=1
and is_deleted = 0
and status = 1
and article_type = #{articleType,jdbcType=TINYINT}

and section = #{section,jdbcType=TINYINT}

Error: FUNCTION dev_operation.MAX does not exist
reason: mysql query function when used, after the function name can not have spaces

修改后代码：
select MAX(article_order) as
from mall_school_article
where 1=1
and is_deleted = 0
and status = 1
and article_type = #{articleType,jdbcType=TINYINT}

and section = #{section,jdbcType=TINYINT}
