我想通过以下查询删除所有记录 return

Question

我想使用 delete 而不是 select 子句（雪花）。

WITH duplicates as(
 select row_number()over(partition by ASCII,keyt,prodt,counter,batch_id ,batch_time,overall_level,is_f,is_s,is_c order
                         by batch_time DESC)as r,
                 * from temp_table
                where batch_time BETWEEN '2021-12-01' and '2021-12-31')
                select count(*) from duplicates as d where r>1 order by keyt;

Answer 1

根据您提供的查询，您似乎没有构成唯一键的列，因此一种选择如下。

--- 未测试

CREATE TABLE new_table LIKE temp_table ;
INSERT INTO new_table SELECT DISTINCT * FROM temp_table;
ALTER TABLE temp_table SWAP WITH new_table;
