A SAS/ACCESS view is an interface view, also called a view descriptor, which accesses
DBMS data that is defined in a corresponding access descriptor.
Using SAS/ACCESS software, you can create an access descriptor and one or more
view descriptors in order to define and access some or all of the data described by one
DBMS table or DBMS view. You can also use view descriptors in order to update
DBMS data, with certain restrictions.
In addition, some SAS/ACCESS products provide a dynamic LIBNAME engine
interface. If available, it is recommended that you use SAS/ACCESS LIBNAME
statement to assign a SAS libref to your DBMS data because it is more efficient and
easier to use than access descriptors and view descriptors. The SAS/ACCESS dynamic
LIBNAME engine enables you to treat DBMS data as if it were SAS data by assigning a
SAS libref to DBMS objects. Using a SAS/ACCESS dynamic LIBNAME engine means
that you can use both native DATA step views and native PROC SQL views to access
DBMS data instead of view descriptors.
See Chapter 31, “About SAS/ACCESS Software,” on page 703 or the SAS/ACCESS
documentation for your database for more information about SAS/ACCESS features.
For information about using SAS/ACCESS view descriptors created in an earlier release,
see Chapter 33, “SAS 9.4 Compatibility with SAS Files from Earlier Releases,” on page
Note: Starting in SAS 9, PROC SQL views are the preferred way to access relational
DBMS data. You can convert existing SAS/ACCESS view descriptors into PROC
SQL views by using the CV2VIEW procedure. This enables you to use the
LIBNAME statement to access your data. See the CV2VIEW Procedure in
SAS/ACCESS for Relational Databases: Reference.
