Notes
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 Implémentation d'une classe Command pour une extension pour le traitement des données.
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. |
