2、使用sql的方式 代码语言:javascript 代码运行次数:0 运行 AI代码解释 /*使用sql方式,先有数据,后利用sql方式建立索引*/proc sql;crate index y onidx(y);/*单一索引*/create index xy onidx(y,x);/*复合索引*/quit; 3、使用datasets方式
proc sql noprint;create tabletest1(mean num,std num,min num,max num);insert into test1setmean=(selectmean(age)fromsashelp.class),std=(selectstd(age)fromsashelp.class),min=(selectmin(age)fromsashelp.class),max=(selectmax(age)fromsashelp.class);quit ↑向右滑动查看全部代码↑ 上述代码使用 ...

SAS generally can not handle a many-to-many mergeproperly by a simple MERGE-BY statement (although a complex MERGE accompanying an advanced DATA stepcan be used). In this situation, an easier and more straightforward alternative is to employ PROC SQL underSAS/Base. This talk will focus on ...
