Hi,
I am running a query that I feel shouldn't be taking as long as it does to
execute. The query is as follows;
SELECT traffic.trafficin.bytes_in as bytes_in,
round(cache.server.serverallkbytes_in) as serverallkbytes_in,
cache.server.tstamp as tstamp FROM traffic.trafficin LEFT JOIN cache.server
ON(from_unixtime(traffic.trafficin.time,"%Y %M %d %H
%i")=date_format(cache.server.tstamp,"%Y %M %d %H %i")) WHERE (
traffic.trafficin.name="em0" AND cache.server.tstamp > 0) AND
((date_format(cache.server.tstamp,'%Y-%m-%d') BETWEEN "2008-05-31" AND
"2008-06-10" ))
Here's the output from the explain;
+----+-------------+-----------+-------+-------------------+---------+---------+-------+-------+-------------+
| id | select_type | table | type | possible_keys | key |
key_len | ref | rows | Extra |
+----+-------------+-----------+-------+-------------------+---------+---------+-------+-------+-------------+
| 1 | SIMPLE | server | range | PRIMARY | PRIMARY | 4
| NULL | 3952 | Using where |
| 1 | SIMPLE | trafficin | ref | namekey,nameindex | namekey |
30 | const | 25867 | Using where |
+----+-------------+-----------+-------+-------------------+---------+---------+-------+-------+-------------+
The strange thing is, when I remove the date range the query executes in an
acceptable time. Can anyone maybe point me in the right direction?
Thanks,
Darryl
