SAS macro facility has been a very important tool in SAS programming for many years. The CALL SYMPUT routine and DATA _NULL_ are the traditional methods to create macro variables from SAS data. However, PROC SQL is much more powerful andefficient in creating macro variables thanks to the in...
Automatic Macro Variables都是全局宏,在macro外定义的也是global micro variable,在macro内定义的是本地宏变量的。(宏变量的作用域不涉及文件(%include问题),数据集或者proc步。因为不是一个层级的东西。) 使用%global var和%local var 定义的变量不能直接赋值,要使用后面的三种方法赋值。 4.宏变量储存在哪? The...
• Create the macro variablein aDATA step withCALL SYMPUTXwhen the global symbol table is specified. • Define a global macro variable with theINTO clauseon thePROC SQL SELECTstatement. Where and When they can be used? You can reference global macro variables throughout the SAS session in ...
I have a quite simple step in my progam, where I create a macro variable which should contain values of the variable NAME (character).PROC SQL NOPRINT; SELECT DISTINCT UPCASE(name) INTO :ListOfVars SEPARATED BY "# " FROM contents; QUIT;...
自动生成宏变量有两种方法,data步里用call symputx(),或者proc sql中用select into:。 零售项目中,万同学的代码里有很多select into:的使用;唐同学的宏里面就有不少call symput()。 call symputx的用法举例: /*6.1b using symputx to create a macro variable*/ /*生成宏变量jane_age,取值为Data步生成的数据...
我想循环使用逗号分隔的宏变量,如下所示,我也在proc sql语句的where条件中使用该变量: %let example = (1, 2, 3, 4) 我发现以下语法几乎涵盖了我的情况: %macro px; %let value = 1 2 3 4; %local i next_value; %let i=1; %do %while (%scan(&value, &i) ne ); ...
DCREATE creates an external directory. The following macro functions are new: SYMEXIST indicates the existence of a macro variable. SYMGLOBL indicates whether a macro variable has global scope in the DATA step during DATA step execution.
(This is not true if you want a macro variable for a title or label, then you want it formatted). So, these macro variables ought to work in your PROC SQL. %let first_day=%sysfunc(intnx(month, %sysfunc(today()),-1,b)); %let last_day=%sysfunc(intnx(month, %sysfunc(today()),...
