I want to partition a mysql table by datetime column. One day a partition.The create table scripts is like this:
CREATE TABLE raw_log_2011_4 (
id bigint(20) NOT NULL AUTO_INCREMENT,
logid char(16) NOT NULL,
tid char(16) NOT NULL,
reporterip char(46) DEFAULT NULL,
ftime datetime DEFAULT NULL,
KEY id (id)
) ENGINE=InnoDB AUTO_INCREMENT=286802795 DEFAULT CHARSET=utf8
PARTITION BY hash (day(ftime)) partitions 31;
But when I select data of some day.It could not locate the partition.The select statement is like this:
explain partitions select * from raw_log_2011_4 where day(ftime) = 30;
when i use another statement,it could locate the partition,but I coluld not select data of some day.
explain partitions select * from raw_log_2011_4 where ftime = '2011-03-30';
Is there anyone tell me How I could select data of some day and make use of partition.Thanks!
