alias

Of course it isn't possible to write SELECT (some subselect) AS blah FROM t WHERE blah = 'const' What is the best way to do this? SELECT (some subselect) FROM t WHERE (some subselect) = 'const' ? View? Stored Function? HAVING? other? manji you can move (some subselect) as table in the FROM : SELECT s.blah FROM t, (some subselect) s WHERE t.id = s.id AND s.blah = 'const' 来源： https://stackoverflow.com/questions/5720983/reuse-subquery-from-select-expression-in-where-clause

I've created a stored procedure where i want to add an alternative order by clause. The problen is that the query failed on a "Invalid column name 'aantal regels'" Here is the query I have now. SELECT l.lead_id, l.afdeling_id, l.advertentie_id, l.naam, l.type, l.status, l.herkomst, l.aanmaakdatum, l.klant_id, l.overigegegevens, af.afdelingsnaam, (SELECT COUNT(lead_regel_id) FROM Lead_regel As lr Where Lr.lead_id = l.lead_id And lr.status <> 100 ) AS aantal_regels, (SELECT COUNT(lead_id) FROM Lead_unread As lu Where lu.lead_id = l.lead_id And lu.user_id = @uid ) As lead_ongelezen, (SELECT COUNT

I am writing custom Powershell cmdlets for my application and I need to provide Aliases to some cmdlets. So lets say I have cmdlet Get-DirectoryListing and I want to add Alias (say 'gdl') to this cmdlet. How can I do this? The AliasAttribute doesn't work here, since it works only with Properties, Indexers or Field declarations. Also I know we can use Set-Alias command, but don't know where to put it. Is it possible to programmatically add multiple aliases to a cmdlet? You need to create a psm1 file ( powershell module ) where you specific your dll with yours cmdlets to load and add aliases in

I absolutely need an extern alias for System.Core in my project. Unfortunately, in a .Net 4.0 project, you cannot even add a reference to System.Core because, apparently, the build system includes it by default. Does anyone have any idea on how I can coerce the system to let me specify an extern alias for this lib? Thanks! This question is old but I ran into the same problem. As far as I understood, this is due to Visual Studio implicitly adding a reference to System.Core. You can override this by editing your csproj msbuild file and adding: <PropertyGroup>

需求总是一个接一个。 missed call需要一个单独的图标，点击进入，而missed call 本身在linhone activity中。 思路，使用activity alias。 当然，需要intent启动activity，也就需要filter 在android的应用程序可以有多个Activity，每个Activity是同级别的，那么在启动程序时，最先启动哪个Activity呢？有些程序可能需要显示在程序列表里，有些不需要。怎么定义呢？ android.intent.action.MAIN 决定应用程序最先启动的Activity 。 android.intent.category.LAUNCHER决定应用程序是否显示在程序列表里。 因为你的程序可能有很多个activity， 只要xml配置文件中有这么一个intent-filter，而且里面有这个launcher，那么这个activity就是点击程序时最先运行的那个activity。 如果只有一个Activity，没有这两句也可以。 隐藏icon实际上就是注释掉intent-filter中的一句 <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category

I like to have a command-line calculator handy. The requirements are: Support all the basic arithmetic operators: +, -, /, *, ^ for exponentiation, plus parentheses for grouping. Require minimal typing, I don't want to have to call a program interact with it then asking it to exit. Ideally only one character and a space in addition to the expression itself should be entered into the command line. It should know how to ignore commas and dollar (or other currency symbols) in numbers to allow me to copy/paste from the web without worrying about having to clean every number before pasting it into

I need to update a SQLite table. The table looks like: ID | Address | CallNumber | RefID -----+--------------------+------------------------------------------- ef78 | library | 2002/13 | 100002 no56 | Lit | 0189 | 100003 rs90 | temp | | 100003 For every column with Address = "Lit" there is a column Address = 'temp' with the same RefID. Now I need to update each Address = "temp" with the value "CallNumber" from the column with the same RefID. The updated table should look like: ID | Address | CallNumber | RefID -----+--------------------+------------------------------------------- ef78 |

alias Alias不带参数或使用-p选项在标准输出上以“name=value”的形式打印别名列表。当提供参数时，为其值给定的每个名称定义一个别名。值中的尾随空格将导致在扩展别名时检查下一个单词是否替换别名。对于参数列表中没有为其提供值的每个名称，将打印别名的名称和值。别名返回true，除非给出没有为其定义别名的名称。 此命令的适用范围：RedHat、RHEL、Ubuntu、CentOS、Fedora。 1 、语法 alias [-p] [name[=value] ...] 2 、选项列表 选项 说明 -p 以“key=val”的方式列出所有别名 3 、实例 删除已经定义的别名 [root@localhost ~]# alias // 查看已经定义别名， mytail 已经不存在 alias cp='cp -i' alias l.='ls -d .* --color=auto' alias ll='ls -l --color=auto' alias ls='ls --color=auto' alias mv='mv -i' alias rm='rm -i' alias which='alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde' 做了一个Linux学习的平台，目前出来一个雏形
