删除表中TimeStamp最小的位置

Question

我想在我的表中删除行，其中我有最小的时间戳值。

DELETE FROM `table_name` WHERE `time_Stamp` =MIN(`table_name.time_Stamp`)

Answer 1

DELETE FROM table_name WHERE time_Stamp =(select MIN(a.time_Stamp) from table_name a)

Answer 2

首先你做一个像

这样的选择语句

select * FROM table_name WHERE time_Stamp =(select MIN(table_name.time_Stamp) from table_name)

并检查您是否获得了所有正确的记录，然后您可以使用

DELETE FROM table_name WHERE time_Stamp =(select MIN(table_name.time_Stamp) from table_name)

Answer 3

E.g：

DELETE x 
  FROM my_table x 
  JOIN 
     ( SELECT MIN(a) min_a FROM my_table ) y 
    ON y.min_a = x.a;
