用于删除表中最近的条目的存储过程的问题

Question

我写的查询是：

delete from featured where featuredID IN(
select top(@removeAmnt) * from featured 
order by featured.createdon asc)

似乎不起作用。我得到的错误是，“当EXISTS没有引入子查询时，只能在选择列表中指定一个表达式。”我不熟悉sql查询。我基本上试图通过他们的createdon字段来命令这些字段的默认值是日期函数。另外，sp允许传入值removeAmnt，这是将从顶部选择要删除的表条目数。

Answer 1

您很可能需要删除*：

delete from featured where featuredID IN(
select top(@removeAmnt) featuredID  from featured 
order by featured.createdon asc)

Answer 2

你没有提到你得到的结果，但你在in子句中的选择不应该是*而是featureID。

delete from featured 
where featuredID IN(
                    select top(@removeAmnt) featured.featuredid from featured 
                    order by featured.createdon as
                    )
