Just do "> /var/lib/mysql/slow-queries.log" it will clear the log.

Hi
Because of that, those queries don't use index.
log-queries-not-using-indexes works even if query time less than
long-query-time.

Hi all,
I am using Mysql Ver 14.14 Distrib 5.1.58 in which i enabled slow query log
by setting below parameters in my.cnf :
log-slow-queries=/usr/local/mysql/slow-query.log
long_query_time=100
log-queries-not-using-indexes
I am assuming from the inf. from the internet that long_query_time is in
12 matches
