阅读更多关于 Invoking SAS 9.2 to edit a program from the command line (windows)

问题 I've been Googling for an hour and can't find what should be the easiest thing. I want to invoke SAS from the command line to edit a SAS program. If I do this: C:\Program Files\SAS\SASFoundation\9.2(32-bit)\sas.exe mysasprogram.sas it simply executes mysasprogram.sas. Help! Thanks! 回答1: Create files: E:\sasedit.bat set _pgm=%1 start "start" "C:\Program Files\SASHome\SASFoundation\9.3\sas.exe" -autoexec "E:\autoexec.sas" E:\autoexec.sas %let _pgm=%sysget(_pgm); dm "whost;include '&_pgm';";

SAS: Execute SAS code using hotkey

阅读更多关于 SAS: Execute SAS code using hotkey

问题 I want to execute code which is independent of my current program via keyboard shortcuts within the Enhanced Editor in SAS 9.4 for Windows. I've achieved this with limited success being able to execute only macro statements. However, I want to be able to execute non-macro statements, too. How do I do this? Here's what I've figured out so far. General Setup Get to the KEYS menu by either entering "KEYS" into the command prompt or submitting dm 'keys'; For one of the keys, enter the definition

浅谈Azure Storage的安全性

阅读更多关于浅谈Azure Storage的安全性

在今天的博文中我们将讨论Azure Storage的安全性以及如何使用共享访问签名（SAS）和存储的访问策略来控制对容器和Blob的访问。SAS基本上是带有查询参数的URI，该查询参数指定诸如到期时间，权限和签名等选项。我将在本文后面详细介绍这些内容。请注意，共享访问签名也可以与表和队列一起使用，但是我将仅在Blob存储方面进行讨论什么是共享访问签名（SAS）共享访问签名（SAS）是URI，它允许使用者在指定时间范围具有访问存储资源（例如blob或容器）所允许的权限。时间跨度和权限可以从存储的访问策略中得出，也可以在URI中指定。可能有得朋友看到这里会提出我使用存储账户密钥就可以了，为什么要使用此功能？因为这允许客户端在不知道我们存储账户密钥的情况下访问存储帐户中的容器和Blob。从安全的角度考虑，如果将存储帐户密钥放在客户端应用程序中，则它可能会遭到******，并且可能会被他人窃取和使用，甚至会用感染了病毒的文件替换正常的文件。使用存储帐户密钥，对存储帐户的访问没有限制。在企业中的实际环境中，无限访问可能不是我们想看到的权限控制场景。默认的容器权限在控制对Blob存储的访问时，首先要使用容器权限。可以将blob存储中每个容器的权限设置为如下权限之一： Private：禁止公众访问Blob或容器 Blob：Blob的公共读取权限 Container

In SQL, is HAVING processed before or after SELECT?

阅读更多关于 In SQL, is HAVING processed before or after SELECT?

问题 I was surprised to find that the following works: SELECT name, height * weight as inchpounds FROM sashelp.class HAVING inchpounds > 5000; Since I thought the HAVING clause was processed strictly before the SELECT clause. Is this in fact a false assumption on my part? Or is this peculiar to SAS's implementation of SQL? 回答1: Strictly speaking, and if I remember well, the SQL standard define HAVING clause to be processed before the SELECT clause. So, an alias defined in the SELECT, cannot be

Determine rates of change for different groups

阅读更多关于 Determine rates of change for different groups

问题 I have a SAS issue that I know is probably fairly straightforward for SAS users who are familiar with array programming, but I am new to this aspect. My dataset looks like this: Data have; Input group $ size price; Datalines; A 24 5 A 28 10 A 30 14 A 32 16 B 26 10 B 28 12 B 32 13 C 10 100 C 11 130 C 12 140 ; Run; What I want to do is determine the rate at which price changes for the first two items in the family and apply that rate to every other member in the family. So, I’ll end up with

Generate multiple lags through loops in SAS?

阅读更多关于 Generate multiple lags through loops in SAS?

问题 I'm trying to generate 20 lags for a variable. To generate the first lag, I use the following statement: data temp.data2; set temp.data1; by gvkey fyear; lag1 = ifn(gvkey=lag(gvkey) and fyear=lag(fyear)+1,lag(mv),.); lag2 = ifn(gvkey=lag(gvkey) and fyear=lag(fyear)+1,lag(lag1),.); etc. run; Don't want to repeat 20 times. Is there a way to do this through a loop? Thanks a lot! 回答1: You would have to maintain your own array of mv values and assign the lag values from that. The array would be
