Using a BY statement allows us to determine the first and last observation in the "by-group," i.e., all the records with the same value in the variable specified in the BY statement (and often called the "by-variable"). When you use a BY statement in the DATA step, SAS creates two temporary variables that may be used only in that DATA step.How to extract first 3 letters and last letter by using proc sql Posted 03-08-2018 05:36 AM (11145 views) ...
