Hi all,

do there is a single way to copy only dataset structure?

I mean, I have a dataset with C columns and R rows, a would have a second dataset with the same C columns but with 0 rows.

Many thanks.

Regards

Hi Haikuo,

Both works correctly, the first one is a littel bit faster.

Many thanks for your reply.

Antonio,

As a side note, if you are planning doing the same on datasets other than SAS tables, such as Oracle, sybase, SQL server etc, you may need to use the following standard SQL syntax:

CREATE TABLE want AS SELECT * FROM have  WHERE 1=0

and wrap it up using SAS pass-through. where condition can be anything not TRUE.

Please note: proc sql options such as inobs=, outobs= may not work in this kind of situation.

I don't know how standard it is, but SAS SQL offers the command :

CREATE TABLE want LIKE have;

to create an empty table with the same structure as another table.
