IDbConnectionExtension Interface


Represents additional connection properties that can be implemented by SQL Server Reporting Services data processing extensions.

public interface class IDbConnectionExtension : IDisposable, Microsoft::ReportingServices::DataProcessing::IDbConnection
public interface IDbConnectionExtension : IDisposable, Microsoft.ReportingServices.DataProcessing.IDbConnection
type IDbConnectionExtension = interface
    interface IDbConnection
    interface IDisposable
    interface IExtension
Public Interface IDbConnectionExtension
Implements IDbConnection, IDisposable


The IDbConnectionExtension interface enables you to implement an extension of the IDbConnection interface, which adds additional functionality for authenticating a connection to a data source. The IDbConnectionExtension interface can be used to build a custom data processing extension. For more information about Connection classes, see Implementing a Connection Class for a Data Processing Extension.

An application does not create an instance of the IDbConnectionExtension interface directly, but creates an instance of a class that implements IDbConnectionExtension.

Classes that implement IDbConnectionExtension must also implement all required members, and typically define additional members to add provider-specific functionality. Because IDbConnectionExtension inherits from IDbConnection, you must also implement all of the IDbConnection members as part of your Connection class including those members from IExtension.



Gets or sets the string used to open a database.

(Inherited from IDbConnection)

Gets the time to wait, while trying to establish a connection, before terminating the attempt and generating an error.

(Inherited from IDbConnection)

Sets the username of the user that is impersonated while queries are executed. This property is ignored by the report server if impersonation is not supported by the data provider.


Indicates whether the connection should use integrated security rather than supply a username and password.


Gets the localized name of the extension to be displayed in a user interface.

(Inherited from IExtension)

Sets the password to use when connecting to the database. Overrides any password specified in the connection string.


Gets or sets the username to use when connecting to the database. Overrides any username specified in the connection string.



Begins a database transaction.

(Inherited from IDbConnection)

Closes the connection to the database.

(Inherited from IDbConnection)

Creates and returns a Command object associated with the connection.

(Inherited from IDbConnection)

Initializes a database connection with the settings specified by the ConnectionString property of the provider-specific Connection object.

(Inherited from IDbConnection)

Used to pass custom configuration data to an extension.

(Inherited from IExtension)
