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 |

| 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. |
