2、告诉我test类 方法名 第一个字母大写。 刚创建项目的时候我就把test包给删除了。

实验 本期我们用 MySQL 提供的 DBUG 工具来研究 MySQL 的 SQL 处理流程。 起手先造个实例 ?...我们来做一两个实验,说明 DBUG 包的作用: 先设置一个简单的调试规则,我们设置了两个调试选项: d:开启各个调试点的输出 O,/tmp/mysqld.trace:将调试结果输出到指定文件 ?...本次实验中,我们借助了 MySQL 的 DBUG 包,来让 MySQL 将处理过程暴露出来。
调试模式开关,默认未启用 DBUG(Bool) DUBG模式会在控制台输出查询的关键信息,方便定位错误 require('lib-qqwry').DBUG().info() 开启调试模式并初始化...qqrry.DBUG(false) 关闭调试模式 8.

看下面: inline bool unique_add(void *ptr) { DBUG_TRACE; DBUG_PRINT("info", ("tree %u - %lu", tree.elements_in_tree
只需要在 appsettings.json 中将 LogLevel 的 Default 设置为 Debug 等级,可以在运行时看到从开发者编写的 SQL 语句加上参数的实际 SQL 语句,大概内容如下 dbug
