DBPROP_DATASOURCE_TYPE

Property group: Data Source Information

Property set: DBPROPSET_DATASOURCEINFO

Type: VT_I4

Typical R/W: R

Description: Data Source Type

Following are returned values of this property and resulting behaviors:

DBPROPVAL_DST_TDP—The provider is a tabular data provider.
DBPROPVAL_DST_MDP—The provider is a multidimensional provider.
DBPROPVAL_DST_TDPANDMDP—The provider is both a TDP and an MDP.
DBPROPVAL_DST_DOCSOURCE—The provider supports direct URL binding and is a document source provider. A consumer can expect a document source provider to exhibit the following behavior:
- When binding to a collection and requesting a rowset, the resource rowset defines the shape of that rowset.
- When creating a new row via ICreateRow::CreateRow, the container class is defined to be a folder and the default columns of the new row are the columns of the resource rowset.

The columns of the resource rowset are defined in the following table. Distributed Authoring and Versioning (DAV) is a protocol enhancement to HyperText Transfer Protocol (HTTP). For more information about Microsoft's implementation of DAV for resource rowsets, see the DAV namespace discussion in the Exchange Platinum section of the Platform SDK.

Column name	Column ID	Type indicator	Description	DAV property
RESOURCE_PARSENAME	DBROWCOL_PARSENAME	DBTYPE_WSTR	Read-only. URL of the resource. This name is usually a relative URL, although it can be an absolute URL. If the resource is the root of a tree, its parse name is defined to be an empty string.	DAV:lastpathsegment
RESOURCE_PARENTNAME	DBROWCOL_PARENTNAME	DBTYPE_WSTR	Read-only. URL of the parent resource. The string always contains an absolute URL. If the resource is the root of a tree, its parent name is defined to be an empty string.	DAV:parentname
RESOURCE_ABSOLUTEPARSENAME	DBROWCOL_ABSOLUTEPARSENAME	DBTYPE_WSTR	Read-only URL of the resource. This name is always an absolute URL and for nonroot resources is the concatenation of its parent name and its parse name.	DAV:href
RESOURCE_ISHIDDEN	DBROWCOL_ISHIDDEN	DBTYPE_BOOL	VARIANT_TRUE: The resource is hidden. Therefore, no row for it will be returned in rowsets unless the command that created the rowset explicitly selected rows where RESOURCE_ISHIDDEN is VARIANT_TRUE.	DAV:ishidden
RESOURCE_ISREADONLY	DBROWCOL_ISREADONLY	DBTYPE_BOOL	VARIANT_TRUE: The resource is read-only. Attempts to open this resource with DBBINDURLFLAG_WRITE return DB_E_READONLY. This property can be edited even when the resource has been opened only for reading.	DAV:isreadonly
RESOURCE_CONTENTTYPE	DBROWCOL_CONTENTTYPE	DBTYPE_WSTR	The MIME type of the document; for example, "text/html".	DAV:getcontenttype
RESOURCE_CONTENTCLASS	DBROWCOL_CONTENTCLASS	DBTYPE_WSTR	The likely use of the document. This might correspond to the Microsoft® Office template used to create the document.	DAV:contentclass
RESOURCE_CONTENTLANGUAGE	DBROWCOL_CONTENTLANGUAGE	DBTYPE_WSTR	The language in which the content is written; for example, "U.S. English".	DAV:getcontentlanguage
RESOURCE_CREATIONTIME	DBROWCOL_CREATIONTIME	DBTYPE_FILETIME	Read-only. Specifies a FILETIME structure containing the time the resource was created. The time is reported in Coordinated Universal Time (UTC) format.	DAV:creationdate
RESOURCE_LASTACCESSTIME	DBROWCOL_LASTACCESSTIME	DBTYPE_FILETIME	Read-only. Specifies a FILETIME structure containing the time that the resource was last accessed. The time is in UTC format. The FILETIME members are zero if the provider does not support this time member.	DAV:lastaccessed
RESOURCE_LASTWRITETIME	DBROWCOL_LASTWRITETIME	DBTYPE_FILETIME	Read-only. Time when the resource was last modified. The time is stored in a FILETIME structure in UTC format. If the provider does not support the time member, the remaining FILETIME members are set to zero.	DAV:getlastmodified
RESOURCE_STREAMSIZE	DBROWCOL_STREAMSIZE	DBTYPE_UI8	Read-only. Size of the resource's default stream, in bytes.	DAV:getcontentlength
RESOURCE_ISCOLLECTION	DBROWCOL_ISCOLLECTION	DBTYPE_BOOL	Read-only. VARIANT_TRUE: The resource is a collection. VARIANT_FALSE: The resource is atomic.	DAV:iscollection
RESOURCE_ISSTRUCTUREDDOCUMENT	DBROWCOL_ISSTRUCTUREDDOCUMENT	DBTYPE_BOOL	VARIANT_TRUE: The resource is a structured document. VARIANT_FALSE: The resource is not a structured document. It could be a collection or an atomic resource.	DAV:isstructureddocument
DEFAULT_DOCUMENT	DBROWCOL_DEFAULTDOCUMENT	DBTYPE_WSTR	Read-only. This resource contains a URL to the default simple document of a folder or a structured document. This is used when the default IStream is requested from a resource. This property is blank for atomic resources.	DAV:defaultdocument
CHAPTERED_CHILDREN	CHAPTERED_CHILDREN	OLE DB Chapter	Optional. Read-only. Specifies the chapter of the rowset containing the children of the resource.
RESOURCE_DISPLAYNAME	DBROWCOL_DISPLAYNAME	DBTYPE_WSTR	Read-only. Display name of the resource.	DAV:displayname
RESOURCE_ISROOT	DBROWCOL_ISROOT	DBTYPE_BOOL	Read-only. VARIANT_TRUE: The resource is a root of a collection. Can be used with RESOURCE_ISCOLLECTION.	DAV:isroot
