使用 select 语句删除行

Question

我有以下查询：

SELECT a.* FROM id_stats a
join id_list b
on a.id = b.id
and a.start_date NOT between b.start_date::date and DATEADD(day,7,b.start_date::date)

returns 我想从 id_stats table 中看到的行，但是当我尝试删除时出现错误：

DELETE a FROM id_stats a
join id_list b
on a.id = b.id
and a.start_date NOT between b.start_date::date
and DATEADD(day,7,b.start_date::date)

错误：

SQL compilation error: syntax error line 1 at position 7 unexpected 'a'. syntax error line 2 at position 0 unexpected 'join'.

Answer 1

根据上面的评论，这里是解释语法的参考文档。没有 JOIN 也没有 ON。是 using 和 where。

https://docs.snowflake.com/en/sql-reference/sql/delete.html#syntax

DELETE FROM id_stats a 
 using id_list b 
 where a.id = b.id 
   and a.start_date NOT between b.start_date::date and DATEADD(day,7,b.start_date::date)
