IDbCommand Interface

 

Updated: February 25, 2016

Represents a statement that is executed while an open connection to a data source exists.

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)

public interface IDbCommand : IDisposable

NameDescription
System_CAPS_pubpropertyCommandText

Gets or sets the text command to run against the data source.

System_CAPS_pubpropertyCommandTimeout

Gets or sets the wait time before terminating the attempt to execute a command and generating an error.

System_CAPS_pubpropertyCommandType

Indicates or specifies how the CommandText property is interpreted (as text, a stored procedure, etc.).

System_CAPS_pubpropertyParameters
System_CAPS_pubpropertyTransaction

Gets or sets the transaction in which the Command object of a SQL Server Reporting Services data provider executes.

NameDescription
System_CAPS_pubmethodCancel()

Attempts to cancel the execution of an IDbCommand.

System_CAPS_pubmethodCreateParameter()

System_CAPS_pubmethodDispose()

(Inherited from IDisposable.)

System_CAPS_pubmethodExecuteReader(CommandBehavior)

Executes the CommandText against the Connection and builds an IDataReader.

The IDbCommand interface enables you to implement a Command class, which represents a statement that is executed at a data source. For more information about Command classes, see Implementing a Command Class for a Data Processing Extension.

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

Classes that implement IDbCommand must also implement all required members, and typically define additional members to add provider-specific functionality.

When you implement from the IDbCommand interface, you should implement the following constructors:

Item

Description

PrvCommand()
