ACCESS Procedure Reference |
Generates unique SAS names based on item names.
Optional statement |
|
Applies to: |
view descriptor
|
The UNIQUE= statement specifies whether
unique SAS variable names should be generated for items. The UNIQUE= statement
can be used only when creating a view descriptor.
The default value, N, enables you to enter duplicate
SAS variable names. You must resolve these duplicate names before you create
view descriptors based on the access descriptor.
If you specify a value of Y and duplicate SAS variable
names exist, numbers are appended to any SAS names that are duplicated as
the result of truncation. For example, if you enter a value of Y for the
UNIQUE= statement, two instances of the item ADDRESS would be changed to ADDRESS
and ADDRESS0.
Note: If you specified a value of Y for
the ASSIGN= statement when you created the access descriptor on which this
view descriptor is based, you cannot specify a UNIQUE= statement. ![[cautionend]](../../../../common/61925/HTML/default/images/cautend.gif)

is a valid alias for this option.
