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
