Aids implementation of the IDbDataAdapter interface. Inheritors of DbDataAdapter implement a set of functions to provide strong typing, but inherit most of the functionality needed to fully implement a DataAdapter.

The DbDataAdapter class inherits from the DataAdapter class and helps a class implement a DataAdapter designed for use with a relational database.

An application does not create an instance of the DbDataAdapter interface directly, but initializes an instance of a class that inherits IDbDataAdapter and DbDataAdapter.

Classes that inherit DbDataAdapter must implement the inherited members, and typically define additional members to add provider-specific functionality. For example, the DbDataAdapter class defines the SelectCommand property, and the DbDataAdapter interface defines eight overloads of the Fill method. In turn, the OleDbDataAdapter class inherits the Fill method, and also defines two additional overloads of Fill that take an ADO Recordset object as a parameter.

Notes to Inheritors: When you inherit from the DbDataAdapter class, it is recommended that you implement the following constructors:

Item	Description
PrvDataAdapter ( )	Initializes a new instance of the PrvDataAdapter class.
PrvDataAdapter ( SqlCommand selectCommand )	Initializes a new instance of the PrvDataAdapter class with the specified SQL SELECT statement.
PrvDataAdapter ( string selectCommandText, string selectConnectionString )	Initializes a new instance of the PrvDataAdapter class with an SQL SELECT statement and a connection string.
PrvDataAdapter ( string selectCommandText, SqlConnection selectConnection )	Initializes a new instance of the PrvDataAdapter class with an SQL SELECT statement and a PrvConnection object.

To promote consistency among .NET data providers, you should name the inheriting class in the form Prv DataAdapter where Prv is the uniform prefix given to all classes in a specific .NET data provider namespace. For example, Sql is the prefix of the SqlDataAdapter class in the System.Data.SqlClient namespace.
