Definition

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
