Hinweise

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 Implementieren einer Command-Klasse für Datenverarbeitungserweiterungen.

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.
