WHPHYSTR

Overview

WHDBMSST models the metadata for database management system physical stores in SAS/Warehouse Administrator. To specify DBMS format for a table in a warehouse, from the SAS/Warehouse Administrator Explorer:

Select a table with the right mouse button.
Select Properties from the pop-up menu.
Go to the Physical Storage tab.
Select DBMS as the storage format.

Properties

The following table lists all of the properties for WHDBMSST 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_.

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_.

* 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 detailed metadata about a property and its associated objects through a single method call.

Note	L	No	No	Yes
NValue	N	Yes	Yes	No

Table Options	L	* Default	* Default	No

Property Dependencies

You must define either a database or a library for a physical store instance. If you provide neither, you get an error message. If you provide a library but no database, and a DBMS connection is defined for that library, the value for the DATABASE property will be obtained from the DBMS connection definition. If you supply both a library and a database, the two properties must match (the library must be appropriate for the database). Otherwise, you get an error message.

New properties for WHDBMSST are as follows:

DATABASE

specifies an SCL list of general identifying information about the database connection that is used for this table.

HOST

specifies an SCL list of general identifying information about the host on which this data is accessed.

LIBRARY

specifies an SCL list of general identifying information about the library that is used to load this database table. If the table is not loaded by using a SAS DBMS Libname engine, then no information is returned for this property.

TABLE OPTIONS

specifies an SCL list of options that are used in creating or loading this table.

The LOAD sublist is appropriate for DBMS tables that are created with code generation level 1.1. It contains any DBLOAD statements that are used to create or load the table.

The CREATE and APPEND sublists are appropriate for DBMS tables that are created with code generation level 2.0. The CREATE sublist contains any SQL options that are used to create the table. The APPEND sublist contains any data set options that are used to load the table. One particularly useful option for the APPEND sublist is the data set option BULKLOAD=, which supports bulk loading of DBMS tables.

WHDBMSST is a dependent type. To understand how it relates to other types, see the physical storage models in Relationships Among Metadata Types.
