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).
