1.按照現有表結構,建立一個臨時表,用於分割槽錶轉換
mysql> desc ClientActionTrack;
+---------------+---------------+------+-----+---------+----------------+

| completeTime  | datetime      | YES  |     | NULL    |                |
+---------------+---------------+------+-----+---------+----------------+
11 rows in set (0.01 sec)

partition by RANGE (TO_DAYS(startTime))  (PARTITION  p20150914 values less than (736221)); 

主鍵列增加 資料被放大

2.批量生成分割槽表
export NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
date=`echo $1 | tr -d '-'`
date1=`echo $2 | tr -d '-'`
date2=`echo $1`
date_end=`get_date $2 +1 | tr -d '-'`
while :
    do
      #echo $date
      date3=`get_date $date +1`
      var=`perl ./get_date.pl $date3`
     echo "alter table tmp01 add partition (partition p$date values less than ($var));"
      date2=`get_date $date +1`
      date=`echo $date2 | tr -d '-'`
      #echo $date3
if [ "$date" = "$date_end" ]
       then
        exit
fi
done
You have mail in /var/spool/mail/oracle
oadb01:/home/oracle/mysql> sh ./p1.sh 20150914 20151231 >p1.sql


3.mysql> insert into tmp01 select * from ClientActionTrack;  ---插入資料到臨時表


4.刪除舊錶,rename tmp01為ClientActionTrack;
mysql> drop table ClientActionTrack;
Query OK, 0 rows affected (0.24 sec)

mysql> rename table  tmp01 to ClientActionTrack;

5.訪問分割槽:


以前的查詢方式:
select min(startTime),max(startTime) from ClientActionTrack where starttime >='2015-10-02 00:00:00' and starttime<='2015-10-02 23:59:59'

改造成分割槽後:

SELECT min(startTime),max(startTime) FROM ClientActionTrack PARTITION (p20151002);
