Microsoft.ReportingServices.DataProcessing Namespace

The Microsoft.ReportingServices.DataProcessing namespace is modeled after a subset of the Microsoft .NET data provider interfaces. These interfaces contain the minimal subset of the .NET data provider functionality needed by the report server to process custom data, and do not reflect a fully implemented .NET data provider. You do not need to create a new data processing extension for Reporting Services, if an existing data provider already implements the data processing extension interfaces. As in the case of a .NET data provider, a Reporting Services data processing extension enables you to connect to a data source in order to retrieve data.

Interfaces

	Interface	Description
	IDataMultiValueParameter	Represents a multivalued parameter to a Command object.
	IDataParameter	Represents a parameter to a Command object.
	IDataParameterCollection	Represents a collection of all parameters relevant to a Command object.
	IDataReader	Provides a means of reading one or more forward-only streams of result sets obtained by executing a command at a data source, and is implemented by Reporting Services Data Processing Extensions that access relational databases.
	IDataReaderExtension	Provides a means of reading one or more forward-only streams of result sets obtained by executing a command at a data source, and is used by SQL Server Reporting Services to retrieve aggregation-specific information about a result set.
	IDataReaderFieldProperties	Provides a means of reading field properties from result sets obtained using the IDataReader or IDataReaderExtension interfaces.
	IDbCollationProperties	Represents the collation properties for a connection to a data source, and is implemented by SQL Server Reporting Services data processing extensions that access relational databases.
	IDbCommand	Represents a statement that is executed while an open connection to a data source exists.
	IDbCommandAnalysis	Represents additional command information for analyzing a query and returning a list of parameter names used in the query.
	IDbCommandRewriter	Infrastructure.
	IDbConnection	Represents an open connection to a data source, and is implemented by SQL Server Reporting Services data processing extensions that access relational databases.
	IDbConnectionExtension	Represents additional connection properties that can be implemented by SQL Server Reporting Services data processing extensions.
	IDbConnectionWrapper	Infrastructure.
	IDbTransaction	Represents a transaction to be performed at a data source.
	IDbTransactionExtension	Represents additional transaction properties that can be implemented by SQL Server Reporting Services data processing extensions.

Enumerations

	Enumeration	Description
	CommandBehavior	Describes of the results of the query and its effect on the database.
	CommandType	Specifies how a command string is interpreted.
