Sql代码  

# 在[mysqld] 中输入

#log

log-error="E:/PROGRA~1/EASYPH~1.0B1/mysql/logs/error.log"

log="E:/PROGRA~1/EASYPH~1.0B1/mysql/logs/mysql.log"

long_query_time=2

log-slow-queries= "E:/PROGRA~1/EASYPH~1.0B1/mysql/logs/slowquery.log"

开启慢查询

long_query_time =2  --是指执行超过多久的sql会被log下来，这里是2秒

log-slow-queries= /usr/local/mysql/log/slowquery.log  --将查询返回较慢的语句进行记录

log-queries-not-using-indexes = nouseindex.log  --就是字面意思，log下来没有使用索引的query

log=mylog.log  --对所有执行语句进行记录
