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. |
