MySQL删除查询

Question

我在使用MySQL查询时遇到了一些麻烦。我在一个名为“ID”的表中有一个字段，我想要一个删除该表中所有行的查询，除非它们有一个特定的ID，我希望能够在查询中定义多个ID。

有什么想法吗？

Answer 1

DELETE FROM your_table
WHERE id NOT IN (1,2,3)

Answer 2

DELETE
FROM yourTable
WHERE yourID NOT IN (1,2,3,4) -- place your list here

或者您不想列出您的ID，您可以使用包含您要保留的ID列表的子查询：

DELETE
FROM yourTable
WHERE yourID NOT IN (SELECT * FROM yourTable WHERE ...)

Answer 3

delete from your_table where id not in (1, 2, 4)

Answer 4

您应该尝试此查询：

DELETE FROM tablename WHERE ID NOT IN ('1','2','3');

Answer 5

这应该做的工作

delete from TABLE_NAME where id not in (1,2,3,4,5,6)

（1,2,3,4,5 ...）的

是您要保存的ID的列表。

Answer 6

您还可以在一些额外条件下使用它：

    delete from your_table_name where id not in (select id from your_table_name where necessary=false)
