In my programming practice, I use PROC SQL to solve a lot of programming problems, sometimes it is even impossible to solve a programming problem without using PROC SQL. Since the applications of PROC SQL in SASprogramming are so broad, this paper will only focus on creating macro variables ...
crsid1-crsid3 are assigned values of the data set variable Course_code from each of the first three rows,他们分别对应数据集的前三行的观测的值 如果规定的group数大于实际的数量,那么按照实际多少个来创建宏 createone macro variablethat willhold all values ofa certain data setvariable. procsql nopr...
PROC SQL INTO: order of values when creating a macro variable out of a character Posted 06-24-2013 03:10 AM (11080 views) Dear all,I have a quite simple step in my progam, where I create a macro variable which should contain values of the variable NAME (character)...
RUN_MACRORUN_MACRO 函数用于执行预定义的 SAS 宏,相当于执行 %macro_name。这个函数可以实现在 DATA 步中执行 DATA 步。语法:rc = RUN_MACRO('macro_name' <, variable_1, variable_2, ...>)例如:以下定义了一个按照变量值拆分数据集的宏程序,宏程序中使用了 DATA 步和 PROC DATASETS 过程对数据集进行...

PROC SQL ; CREATE TABLE largest_V1 AS SELECT * FROM countres GROUP BY state HAVING numres = MAX(NUMRES); QUIT; After Step 1, the data set COUNTRES will have one observation for each nursing home id (which is nested within state) that contains the variable numres, which is the row...
Python是一种高级编程语言，提供了多个库，可以连接到MySQL数据库和执行SQL查询。
symputx也不能用在SQL步中,同时SQL不能像SYMPUTX定义local宏变量或者是global宏变量。 一:基本语法 data callsym2;setmacrolib.clinics(where=(lname?'son'));/*这种写法可以直接搜索 where*/run;proc contents data=sashelp.class;run;dataclass;setsashelp.class;run;proc contents data=class;run;data clinic...
PROCSIMILARITYPROCSQL PROC FCMP 和 DATA Step 的区别: 1. Abort Statement: 在PROC FCMP中, Abort 不接受参数; 且,Abort 和 function , subroutines 等是平级的,所以不能在 function 语句内部使用abort语句。 2. Arrays 因为proc fcmp中,在声明function的时候,function 后面用了小括号"()", 所以在指定array...
datastep that generates a macro variable for each processgate, process level, and operation. This is the classic way to create numerous macro variables. By concatenating the system_n_ variable to the end of the macro variable name, a uniquemacro variable is generated for each process operation...
