mongdb 使用linux shell修改数据

Tue, 22 Sep 2015 11:25:00 GMT

1、编写脚步：update.js
/**

* 旉��对象的格式化;

Date.prototype.format = function(format) {

* eg:format="YYYY-MM-dd hh:mm:ss";

var o = {

"M+" :this.getMonth() + 1, // month

"d+" :this.getDate(), // day

"h+" :this.getHours(), // hour

"m+" :this.getMinutes(), // minute

"s+" :this.getSeconds(), // second

"q+" :Math.floor((this.getMonth() + 3) / 3), // quarter

"S" :this.getMilliseconds()

// millisecond

}

if (/(y+)/.test(format)) {

format = format.replace(RegExp.$1, (this.getFullYear() + "")

.substr(4 - RegExp.$1.length));

}

for ( var k in o) {

if (new RegExp("(" + k + ")").test(format)) {

format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k]

: ("00" + o[k]).substr(("" + o[k]).length));

}

return format;

}

var date =new Date();

var createdate=date.format("yyyy-MM-dd hh:mm:ss");

date.setMinutes(date.getMinutes()+5);

var validtime=date.format("yyyy-MM-dd hh:mm:ss");

db.UserOnlineInfo.update(

{

"uid" : "110000350"

{$set : {

"uid" : "110000350",

"createtime" : createdate,

"validtime" : validtime

}});

db.UserOnlineInfo.update(

{

"uid" : "110000351"

{$set : {

"uid" : "110000351",

"createtime" : createdate,

"validtime" : validtime

}});

2、编写shell脚步�Q?br /> #/bin/bash

echo "update mongod begin"

cd /home/mongodb/mongodb-3.0.2/bin

./mongo 192.168.1.122:27108/YouLiao update.js;

echo "update mongod success"

3�?执行脚本�Q?/div>

/home/mongodb/mongodb-3.0.2/bin/mongo 192.168.1.122:27108/YouLiao /root/www/job/mongo-test/update.js

备注�Q?/div>

mongodb查询、删除类�?/div>

1、多表��联删除：

---DELETE---

DELETE from a_msg_push,a_announcement

using a_msg_push,a_announcement

where a_msg_push.announcement_id=a_announcement.id and a_announcement.Create_time<'2014-11-19 23:59:59';

2、子查询删除�Q?/div>

-----------delete--------

DELETE From t_repeat where t_repeat.id in(

SELECT tb.id from (

SELECT * from t_repeat t

where

1=1

and

(t.cid,t.uid ) in (select t1.cid,t1.uid from t_repeat t1 group by t1.cid,t1.uid having count(*) > 1)

and

t.id not in (select min(t2.id) from t_repeat t2 group by t2.cid,t2.uid having count(*)>1)

) as tb )

3、子表删除：

-----------delete--------

DELETE From t_repeat where t_repeat.id not in

(

SELECT tb.id from(

select a.id from t_repeat a where a.id =(

select max(b.id) from t_repeat b where a.cid=b.cid and a.uid=b.uid

)

)as tb

)

如下两条常用sql�Q�统计分�c�L��据，你能说出区别吗？
一、常用sql一�Q?/strong>
select
r.cid,
r.depart_id,
r.employ_id,
r.create_by,
count(DISTINCT r.form_type) as dailyReportNum
FROM
report r
where
1=1
GROUP BY
r.employ_id

二、常用sql二：
select
r.cid,
r.depart_id,
r.employ_id,
r.create_by,
sum(case WHEN df.form_type=1 then 1 else 0 end ) as dailyReportNum
FROM
report r
where
1=1
GROUP BY
r.employ_id
