Properties
The following table lists all of the properties for WHCOLSUM and indicates how you can use each property with metadata API methods
In the table, you can specify properties with a Yes in the Indirect Add column when
you indirectly add one object through another, as described in the documentation for the _UPDATE_METADATA_ method Use this approach to add a new dependent object For details, see “Using _UPDATE_METADATA_” on page 46
You can pass properties with a Yes in the Update column to the
_UPDATE_METADATA_ method, as described in the documentation for this method Use this method to update properties of an existing object For details, see “Using _UPDATE_METADATA_” on page 46
* Req indicates that the property is required; you must provide a value for this
property when you use a given method * Default indicates that the system will provide
a default value for that property if you do not provide one * Auto supplied means that
the property is automatically supplied; any value that you specify for such a property is ignored
Properties with a Yes in the Read Method Expand Parm column are valid with the
expand parameter of the _GET_METADATA_ method This method enables you to get

Trang 384 WHCOLSUM Chapter 3
WHCOLSUM has the following two new properties:
ALIAS specifies a character string for the column name as registered by SAS/Warehouse Administrator
Note that the NAME for a summary column contains the physically stored name, and the ALIAS contains the name as seen through SAS/Warehouse Administrator A column’s NAME and ALIAS are the same, except for MDDB columns
For MDDB columns, the NAME property returns the name as it would be returned through the SASSFIO libname engine when looking at a specific hierarchy The ALIAS property returns the name as seen through SAS/Warehouse Administrator
SUMMARY ROLE specifies a character string for the role of the column in the summary data For
example: CLASS, STATISTIC, ID, FREQUENCY, and TIME.
