The ASSIGN statement indicates whether SAS variable names are automatically generated and whether users can change SAS variable names and other column information the view descriptors created from this access descriptor.
An editing statement, such as ASSIGN, must be specified after the CREATE and database-description statements when you create an access descriptor. See CREATE for more information.
enables you to modify SAS variable names, formats, informats, database contents,
occurrence ranges, and BY keys when you create an access descriptor and when
you create view descriptors that are based on this access descriptor.
value for this statement to generate unique SAS variable names from the first
eight characters of the DBMS column names, according to the rules listed below.
YES, you can change the SAS variable names and other
column information only in the access descriptor. The SAS variable names
and other column information that are saved in an access descriptor are always used when view descriptors are created from the access descriptor;
you cannot change them in the view descriptors.
Default SAS variable names are generated according to these rules:
clientsnumberbecome the SAS names
If the same descriptor has another set of columns with
duplicate names, the numeric suffix begins at the next highest number from
the previous set of duplicate names. For example, if the descriptor has the
duplicate names above and also has the DBMS names
customernode, the default SAS names would be
func$becomes the SAS variable name
If you specify
YES for this statement,
the SAS System automatically resolves any duplicate variable names. However,
if you specify
YES, you cannot specify the CONTENT, FORMAT, INFORMAT,
KEY, MVF (with OCCURS option), RENAME, or RESET statements when you create
view descriptors that are based on the access descriptor.
When the SAS/ACCESS interface encounters the next CREATE
statement to create an access descriptor, the ASSIGN statement is reset to
AN is the alias for the ASSIGN statement.
