【问题描述】：

我在 mysql 中创建了一个用于搜索文章的存储过程。所以当我想调用它时，我得到了这个错误。

SQL 错误 [1038] [HY001]：排序内存不足，请考虑增加服务器排序缓冲区大小

我的代码目的是先根据标题相对排序文章，然后根据描述相对排序。

在增加缓冲区大小（并重新启动 mysql 服务，然后再次调用 sp）之后，我也收到此错误： SQL 错误 [S1000]: 无法从服务器检索事务只读状态

【解决方案1】：

临时解决方案

只运行mysql查询

SET GLOBAL sort_buffer_size = 256000000 // 服务器重启后会重置

设置永久

编辑下面的文件并添加

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

sort_buffer_size = 256000000

sudo 服务 mysql 重启
