How to add a comment in column sysvalue in table VLIBNAM

ChrisNZ — Thu, 22 Sep 2022 06:33:51 GMT

I'm trying to retrieve which user ID was used to allocate a Hadoop library.

I couldn't find a way so thought this could be stored in the comment field at allocation time.

See table SASHELP.VLIBNAM

Any idea on either retrieving the userid used in the libname statement, or on populating the value for comment ?

Perhaps. What does the documentation say about that COMMENT option?

But why not just remember what userid you used when you defined the libref to begin with?

Or ask HIVE to tell you. Most SQL implementations support the keyword USER.

SAS does.

proc sql;
  select user into :userid from sashelp.class(obs=1);
quit;

So try something similar in a pass thru query to HIVE.

The documentation does not say anything about this field as far as I could see.

Good point about using native commands. This works:

select * from connection to HIVE (select current_user() );

or
select * from connection to HIVE (select logged_in_user() );

Thank you Tom.
