如何让我的 SQL 查询删除最近的记录？

Question

我正在尝试删除最近的记录，其中 job_id 等于状态已暂停且不知道此类功能的作业的 ID。有办法吗？

DELETE FROM
  records
WHERE
  **due_date = most recent**
  AND job_id IN (
    SELECT
      id
    FROM
      jobs
    WHERE
      status = 'paused'
  )

Answer 1

试试下面的查询。

DELETE FROM records WHERE due_date IN 
( SELECT due_date FROM records ORDER BY due_date DESC LIMIT 1) 
and job_id IN (SELECT id FROM jobs WHERE status = 'paused') ;

我假设以下 table 架构，否则请更正

CREATE TABLE records(Id integer PRIMARY KEY, due_date date,name varchar2,job_id integer);
CREATE TABLE jobs(Id integer PRIMARY KEY, status varchar2);


INSERT INTO records VALUES(1,'17/12/2015','1','3');
INSERT INTO records VALUES(2,'17/12/2020','2','3');

INSERT INTO jobs VALUES(3,'paused');
INSERT INTO jobs VALUES(4,'paused');
COMMIT;
