开启的步骤:
1. show variables like '%query%';
2. set global long_query_time = 1; 设置慢查询的时间
3. slow_query_log = ON
4. slow_query_log_file = E:programmysql-5.6.44-winx64dataoldboy-slow.log
普通日志记录(general log):
SQL审计 (记录sql的操作语句)
show variables like '%general%';
+------------------+------------------------------------------------+
| Variable_name | Value |
