Question

我知道如何使用以下语句删除一组行：

DELETE FROM my_table WHERE id=23 AND year=2012 AND value=16
DELETE FROM my_table WHERE id=17 AND year=2012 AND value=16
DELETE FROM my_table WHERE id=64 AND year=2012 AND value=16

但我想将上述三个语句组合成一个DELETE，其中id为23,17或64.

在Oracle SQL中执行此操作的语法是什么？

Answer 1

您可以使用SQL IN关键字。例如：

DELETE FROM my_table WHERE id IN (23, 17, 64) AND year=2012 AND value=16

注意： Oracle在列表中限制为1,000个项目。

Answer 2

DELETE FROM my_table 
WHERE id in (17, 23, 64) AND year=2012 AND value=16

Answer 3

您可以链接AND/OR条件以达到相同的效果。在这种情况下，简单的IN可以解决您的目的。

DELETE FROM my_table WHERE id IN (23, 17, 64) AND year=2012 AND value=16

Answer 4

怎么样：

DELETE FROM my_table WHERE (id=23 or id=17 or id=64) AND year=2012 AND value=16

如何在SQL中删除多个值？
