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 ...

使用PROC SQL 是一种从表中快速获取结果并将其抛入变量的好方法。我经常发现,当我想获得一个刚刚加载到表中的记录数时,我可以通过快速 PROC SQL 调用将该计数转换为变量。 PROC SQL; SELECT COUNT(*) INTO:aVariable FROM MyTable ;QUIT; 在上面的例子中,aVariable 将表示 MyTable 中存在多少条记录。 你...

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...
