How to count rows from multiple tables under multiple libraries which are all not even assigned? For example if I need to count rows from all tables which are under libraries starting with "AB_CD_%" (and not all of them are assigned), how to achieve this? SAS internal metadata tables such as dictionary.tables, dictionary.libnames or sashelp.vtable hold information only about assigned libraries, right?

A library doesn't really exist in SAS,  until a libref exists that points to the library.  When you create a library reference, typically with the LIBNAME statement, it "assigns" that libref to a library.    And correct, a library with no libref assigned to it won't be reflected in dictionary tables etc.  because it doesn't exist.

 

It would be possible to use SAS to scan a directory tree for all directories named like "AB_CD_%", and then look for all the SAS datasets in them.  But I don't think that's what you're looking for.

 

It would probably be easiest to run the code to create the library references for libraries you're interested in, then use dictionary tables to get the metadata you want.
