发帖数: 3942 | 1 suppose we use a procedure to get a table from output mode, for example:
output out=dataset ...;
or use ODS output table like:
ods output ods_table_name=dataset;
However in neither way can i use obs= dataset options to restrict the number of observations in output dataset, the following code doesnt work
ods output ods_table_name=dataset(obs=1);
But other dataset options seems OK, say where=, keep=, drop=, ...
couldnt understand why | o****o

4. Restriction: Cannot use with PROC SQL views
5. Default MAX
number of observations in output dataset, the following code doesnt work
