- proc sql noprint;
- select name into :names separated by ","
- from dictionary.columns
- where libname="SASHELP" and memname="CLASS" and upcase(name) like '%T';
- quit;
- data want;
- set sashelp.class;
- vsum=sum(&names);
- run;
1、select name into :names separated by "," 是什么意思?
2、upcase(name) like '%T' 是什么意思?
