Remarks

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()	Initializes a new instance of the PrvCommand class.
PrvCommand(string cmdText )	Initializes a new instance of the PrvCommand class with the text of the query.
PrvCommand(string cmdText, PrvTransaction transaction )	Initializes a new instance of the PrvCommand class with the text of the query, a PrvConnection, and the PrvTransaction.

Properties

CommandText	Gets or sets the text command to run against the data source.
CommandTimeout	Gets or sets the wait time before terminating the attempt to execute a command and generating an error.
CommandType	Indicates or specifies how the CommandText property is interpreted (as text, a stored procedure, etc.).
Parameters	Gets the IDataParameterCollection.
Transaction	Gets or sets the transaction in which the Command object of a SQL Server Reporting Services data provider executes.

Methods

Cancel()	Attempts to cancel the execution of an IDbCommand.
CreateParameter()	Creates a new instance of an IDataParameter object.
ExecuteReader(CommandBehavior)	Executes the CommandText against the Connection and builds an IDataReader.
