mysql - 相同的存储过程，相同的表，不同的数据库给出不同的结果

Question

我有一个存储过程，当我在 MySQL 5 上运行它时，它会给出预期的结果。但是当我尝试在 MariaDB 10.1.22 上运行相同的过程时，它给出了不同的结果。

这是我的存储过程 -

    DELIMITER ;;

我在 MaroiaDB 10.1.22 中得到的结果是不正确的 -

应该是有序的。

谁能告诉我出了什么问题吗？或者它的数据库问题？

提前致谢。

Answer 1

您的任何查询中都没有order by。结果集可以采用任何顺序，因为没有 order by 的结果集(如表)是无序集。

因此，数据库是正确的。您的理解忽略了有关 SQL 的这一重要事实。

添加您想要的order by，结果集将在您使用的任何版本的数据库中进行适当的排序。
