The aliases are available for compatibility only.
For example, if three SAS data libraries each contain a catalog named CATALOG1, then when you concatenate them, you implicitly create a catalog concatenation for the catalogs that have the same name. When a SAS file is opened for input or update, the concatenated libraries are searched and the first occurrence of the specified file is used.
When a SAS file is opened for output, it is created in the first library that is listed in the concatenation. A new SAS file is created in the first library even if there is a file with the same name in another part of the concatenation.
When you delete or rename a SAS file, only the first occurrence of the file is affected. Any time a list of SAS files is displayed, only one occurrence of a file name is shown. Even if the name occurs multiple times in the concatenation, only the first occurrence is shown.
A SAS file that is logically connected to another file such as an index to a data set is listed only if the parent file resides in that same library.
For example, if library ONE contains A. If any library in the concatenation is sequential, then all of the libraries are treated as sequential.
The attributes of the first library that is specified determine the attributes of the concatenation. For example, if the first SAS data library that is listed is "read only", then the entire concatenated library is "read only".
If you specify any options or engines, they apply only to the libraries that you specified with the complete physical name, not to any library that you specified with a libref.
If you alter a libref after it has been assigned in a concatenation, it will not affect the concatenation.Mar 30, · libname DB2 code with SAS?ACCESS for DB2 Showing of 2 messages.
libname DB2 code with SAS?ACCESS for DB2 engine so I can directly read and write DB2 from SAS? Thanks, John. Re: libname DB2 code with SAS?ACCESS for DB2 issues in many db2 shops that directly impact usability w/SAS. Here are 2 SUGI Articles with DB2 libname examples.
Using Data from a PC File.
You can use a LIBNAME statement to read from and write to a data source table or view as if it were a SAS data set. The LIBNAME statement associates a libref with a SAS/ACCESS engine to access tables or views in a spreadsheet or database. Years since I've used SAS, but iirc it has a libname interface to WebDAV, and I think onedrive has WebDAV available.
– sasfrog Jul 2 '15 at When I said "you can't read a dataset without downloading it" it was more a technical observation. Apr 03, · Protecting source data with libname access control The access= option in a libname statement is a good way to make sure you won’t accidentally overwrite source data.
Here’s an example. Next, you use proc sql to access regardbouddhiste.com and create a table with the names of all your sheets and the number of sheets in your workbook. regardbouddhiste.com is something created during each SAS session with information about all of your datasets and libraries.
This section describes the LIBNAME statement that SAS/ACCESS Interface to Oracle supports and includes examples. For details about this feature, see the LIBNAME statement.
