redis hash类型的常用命令

由 故事扮演 提交于 2019-12-23 05:55:28
简介 edis hash 是一个string类型的field和value的映射表，hash特别适合用于存储对象。 Redis 中每个 hash 可以存储 232 - 1 键值对（40多亿） 可以看成具有KEY和VALUE的MAP容器，该类型非常适合于存储值对象的信息， 如：uname,upass,age等。该类型的数据仅占用很少的磁盘空间（相比于JSON） 命令 赋值语法： HSET KEY FIELD VALUE //为指定的KEY，设定FILD/VALUE HMSET KEY FIELD VALUE [FIELD1,VALUE1]…… 同时将多个 field-value (域-值)对设置到哈希表 key 中。 取值语法： HGET KEY FIELD //获取存储在HASH中的值，根据FIELD得到VALUE HMGET key field[field1] //获取key所有给定字段的值 HGETALL key //返回HASH表中所有的字段和值 HKEYS key //获取所有哈希表中的字段 HLEN key //获取哈希表中字段的数量 删除语法： HDEL KEY field1[field2] //删除一个或多个HASH表字段 其它语法： HSETNX key field value 只有在字段 field 不存在时，设置哈希表字段的值 HINCRBY key field

Javascript hash replace error [duplicate]

问题 This question already has answers here : Replace method doesn't work (4 answers) Closed 5 years ago . What's the problem with this? the hash is : #/search=hello/somethingelse/ window.location.hash.replace(/search=([^\/]*)/gi, "search=" + value); EDIT: I want to change just a specific part of the hash not the whole hash . 回答1: hash.replace() does not actually change the hash, only return a value (as it is a String function). Try assigning that result, using: window.location.hash = window

'Do something' if key exists in hash1 and not in hash2

问题 I've written some code that finds overlapping keys in 3 different HoAs that contain some information on which I sort them later: #!/usr/bin/perl use warnings; use strict; my @intersect; for my $key (sort keys %hash1) { if (exists $hash2{$key} && $hash3{$key} ) { my ($hit1, $percent_id1) = @{ $hash1{$key}[-1] }; my ($hit2, $percent_id2) = @{ $hash2{$key}[-1] }; my ($hit3, $percent_id3) = @{ $hash3{$key}[-1] }; push @intersect, "$key\tC1:[$condition1]$hit1 [$percent_id1]\tC2:[$condition2]$hit2

How do you Make the H in Jenkins Poll SCM Schedule actually random

由 橙三吉。 提交于 2019-12-23 04:54:15
问题 I running Jenkins 1.565.1 The docs indicate the H (hash) function to be a random hash of the project name. This does not appear to be true in my case. I set SCM polling to be every 4 hours H H/4 * * * for a number of projects and they get scheduled at 12:00:31 12:00:58 12:00:23 12:00:14 This does not appear to be random at all! Ho do I start them at a random time, and check back every 4 hours. If I change the formula to H H/3 * * * or H H * * * It still has the same starting time, within the

VB6 how to get C-like integer overflow

由 醉酒当歌 提交于 2019-12-23 04:28:10
问题 I want to port this simple hash algorithm to VB6. I have come up with: Public Function simpleHash(hashString As String) As Long Dim hash As Long Dim c As Long Dim i As Integer On Local Error Resume Next hash = 5381 For i = 1 To Len(hashString) c = AscW(Mid$(hashString, i, 1)) hash = hash * 33 + c Next i simpleHash = hash End Function The problem is, despite my On Error statement which suppresses the Error 6: Overflow exceptions, the variable hash is not updated any more if an overflow occurs.

compare multiple hashes for common keys merge values

由 ≯℡__Kan透↙ 提交于 2019-12-23 04:04:45
问题 I have a working bit of code here where I am comparing the keys of six hashes together to find the ones that are common amongst all of them. I then combine the values from each hash into one value in a new hash. What I would like to do is make this scaleable. I would like to be able to easily go from comparing 3 hashes to 100 without having to go back into my code and altering it. Any thoughts on how I would achieve this? The rest of the code already works well for different input amounts,
