IDbConnection Interface
Represents an open connection to a data source, and is implemented by SQL Server Reporting Services data processing extensions that access relational databases.
Namespace: Microsoft.ReportingServices.DataProcessing
Assemblies: Microsoft.ReportingServices.Interfaces (in Microsoft.ReportingServices.Interfaces.dll)
Microsoft.ReportingServices.SharePoint.UI.WebParts (in Microsoft.ReportingServices.SharePoint.UI.WebParts.dll)
Syntax
'Declaration
Public Interface IDbConnection _
Inherits IDisposable, IExtension
'Usage
Dim instance As IDbConnection
public interface IDbConnection : IDisposable,
IExtension
public interface class IDbConnection : IDisposable,
IExtension
type IDbConnection =
interface
interface IDisposable
interface IExtension
end
public interface IDbConnection extends IDisposable, IExtension
The IDbConnection type exposes the following members.
Properties
| Name | Description | |

|
ConnectionTimeout | Gets the time to wait, while trying to establish a connection, before terminating the attempt and generating an error. |
|
LocalizedName | Gets the localized name of the extension to be displayed in a user interface. (Inherited from IExtension.) |

Remarks
The IDbConnection interface enables you to implement a Connection class, which represents a unique session with a data source. The IDbConnection interface can be used to build a custom data provider. 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 IDbConnection interface directly, but creates an instance of a class that implements IDbConnection.
Classes that implement IDbConnection must implement all required members, and typically define additional members to add provider-specific functionality. Because IDbConnection inherits from IExtension, you must also implement the IExtension members as part of your Connection class.
When you implement from the IDbConnection interface, you should also implement the following constructors:
Class |
Description |
|---|---|
PrvConnection() |
Initializes a new instance of the PrvConnection class. |
PrvConnection(string connectionString) |
Initializes a new instance of the PrvConnection class when given a string containing the connection string. |
