SAS如何检索以特定字符串为前缀的数据集列表

Question

in sas, I have a bunch of datasets in one of my libraries

ie:

tmp_dataset_a
tmp_dataset_b
tmp_dataset_c
tmp_dataset_d
dataset1
dataset2

How do I extract a list of the datasets prefixed with tmp ? I would like to store this list so I can access it

Answer 1

Use the SASHElP.VTABLE dictionary table. It stores metadata about the SAS tables, including names.

data want;
set sashelp.vtable;
where memname like 'tmp%';
run;
