使用Mysql中的id从表中删除许多行

Question

我是一名Linux管理员，只掌握Mysql查询的基本知识

我想使用 id ，

删除我桌上ip地址的许多表条目

目前我正在使用

DELETE from tablename where id=1;
DELETE from tablename where id=2;

但我必须删除254个条目，所以这个方法需要几个小时，我怎么能告诉mysql删除我指定的行，因为我想跳过删除254中的一些条目。

删除整个表并导入所需的条目不是一种选择。

Answer 1

最好的方法是使用IN声明：

DELETE from tablename WHERE id IN (1,2,3,...,254);

如果您有连续的ID，也可以使用BETWEEN：

DELETE from tablename WHERE id BETWEEN 1 AND 254;

您当然可以使用其他WHERE子句限制某些ID：

DELETE from tablename WHERE id BETWEEN 1 AND 254 AND id<>10;

Answer 2

如何使用IN

DELETE FROM tableName
WHERE ID IN (1,2) -- add as many ID as you want.

Answer 3

这样的东西可能会让它变得更容易一点，显然你可以用脚本来生成它，甚至可以用excel

DELETE FROM tablename WHERE id IN (
1,
2,
3,
4,
5,
6
);

Answer 4

如果您只需要保留几行，请考虑

DELETE FROM tablename WHERE id NOT IN (5,124,221);

这只保留一些记录并丢弃其他记录。

Answer 5

使用IN条款

   DELETE from tablename where id IN (1,2);

或者您可以合并使用BETWEEN和NOT IN来减少您必须提及的数字。

DELETE from tablename 
where (id BETWEEN 1 AND 255) 
AND (id NOT IN (254));

Answer 6

其他人建议IN，这很好。您还可以使用范围：

DELETE from tablename where id<254 and id>3;

如果要删除的ID是连续的。

Answer 7

如果您的数据中有某些'条件'来计算254个ID，则可以使用：

delete from tablename
where id in 
(select id from tablename where <your-condition>)

或简单地说：

delete from tablename where <your-condition>

在任何情况下，只需对id列的254值进行硬编码就会非常困难。

Answer 8

DELETE FROM table_name WHERE id BETWEEN 1 AND 256;

试试这个。

Answer 9

希望有帮助：

DELETE FROM tablename 
WHERE tablename.id = ANY (SELECT id FROM tablename WHERE id = id);

Answer 10

DELETE FROM tablename WHERE id > 0;
OR
DELETE FROM tablename WHERE id <255;

删除 1 到 254 之间的 id
