Since SAS 7, most SAS names can be up to 32 characters
long.
SAS/ACCESS Interface to Aster
nCluster
supports table names and column names that contain up to 32 characters.
If column names are longer than 32 characters, they are truncated
to 32 characters. If truncating a column name would result in identical
column names, SAS generates a unique name by replacing the last character
with a number. DBMS table names must be 32 characters or less. SAS
does not truncate a name longer than 32 characters. If you have a
table name that is greater than 32 characters, it is recommended that
you create a table view.
The PRESERVE_COL_NAMES=
and PRESERVE_TAB_NAMES= options determine how
SAS/ACCESS Interface
to Aster
nCluster handles case
sensitivity. Aster
nCluster
is not case sensitive, so all names default to lowercase.
Aster
nCluster
objects include tables, views, and columns. They follow these conventions.
-
A name must be from 1 to 64 characters
long.
-
A name must begin with a letter
(A through Z), diacritic marks, non-Latin characters (200-377 octal)
or an underscore (_).
-
To enable case sensitivity, enclose
names in quotes. All references to quoted names must always be enclosed
in quotes, and preserve case sensitivity.
-
A name cannot begin with a _bee
prefix. Leading _bee prefixes are reserved for system objects.
-
A name cannot be a reserved word
in Aster
nCluster, such as
WHERE or VIEW.
-
A name cannot be the same as another
Aster
nCluster object that
has the same type.
