SAS: Create an empty file

There are two ways to create an empty SAS dataset having the same fields and formats as an existing data set. I knew about the DATA step way (shown first) but did not know about the PROC SQL way (shown second):


data work.orig;
a = 1; b = 2; c = 3; output;
a = 2; b = 3; c = 4; output;
format b 3.1 c 4.2; * to show format is copied also ;
run;

data work.copy1;
set work.orig;
delete;
stop;
run;

proc contents data=work.copy1;
run;

proc sql noprint;
create table work.copy2 like work.orig;
quit;
run;

proc contents data=work.copy2;
run;
