WHDBMS is an independent type To understand how it relates to other types, see the physical storage models in “Relationships Among Metadata Types” on page 53

Note: The USERID and PASSWORD attributes are only valid with the _GET_METADATA_ method when the API application is a secure application

Currently, the only secure applications are those that are registered as add-in generators 4

“WHPHYSTR” on page 204

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:

1 Select a table with the right mouse button

2 Select Properties from the pop-up menu.

3 Go to the Physical Storage tab

4 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_” 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

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

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
