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 creates 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, we recommend that you implement the following constructors:

Item

Description

PrvDataAdapter()

Initializes a new instance of the PrvDataAdapter class.

PrvDataAdapter(PrvCommand 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, PrvConnection selectConnection)

Initializes a new instance of the PrvDataAdapter class with an SQL SELECT statement and a PrvConnection object.

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

.NET Framework
