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}
报错:FUNCTION dev_operation.MAX does not exist
原因:mysql在使用函数查询时,函数名后面不能加空格
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}
