System.Data.OleDb Namespace
.NET Framework 1.1
The System.Data.OleDb namespace is the .NET Framework Data Provider for OLE DB.
The .NET Framework Data Provider for OLE DB describes a collection of classes used to access an OLE DB data source in the managed space. Using the OleDbDataAdapter, you can fill a memory-resident DataSet, which you can use to query and update the data source.
For information on how to use this namespace, see the OleDbDataAdapter, the OleDbDataReader, the OleDbCommand, and the OleDbConnection classes. For conceptual information about using this namespace when programming with the .NET Framework, see "Accessing Data with ADO.NET".
Classes
| Class | Description |
|---|---|
| OleDbCommand | Represents an SQL statement or stored procedure to execute against a data source. |
| OleDbCommandBuilder | Automatically generates single-table commands used to reconcile changes made to a DataSet with the associated database. This class cannot be inherited. |
| OleDbConnection | Represents an open connection to a data source. |
| OleDbDataAdapter | Represents a set of data commands and a database connection that are used to fill the DataSet and update the data source. |
| OleDbDataReader | Provides a way of reading a forward-only stream of data rows from a data source. This class cannot be inherited. |
| OleDbError | Collects information relevant to a warning or error returned by the data source. This class cannot be inherited. |
| OleDbErrorCollection | Collects all errors generated by the .NET Framework Data Provider for OLE DB. This class cannot be inherited. |
| OleDbException | The exception that is thrown when the underlying provider returns a warning or error for an OLE DB data source. This class cannot be inherited. |
| OleDbInfoMessageEventArgs | Provides data for the InfoMessage event. This class cannot be inherited. |
| OleDbParameter | Represents a parameter to an OleDbCommand and optionally, its mapping to a DataSet column. This class cannot be inherited. |
| OleDbParameterCollection | Represents a collection of parameters relevant to an OleDbCommand as well as their respective mappings to columns in a DataSet. |
| OleDbPermission | Enables the .NET Framework Data Provider for OLE DB to help ensure that a user has a security level adequate to access an OLE DB data source. |
| OleDbPermissionAttribute | Associates a security action with a custom security attribute. |
| OleDbRowUpdatedEventArgs | Provides data for the RowUpdated event. |
| OleDbRowUpdatingEventArgs | Provides data for the RowUpdating event. |
| OleDbSchemaGuid | Returns the type of schema table specified by the GetOleDbSchemaTable method. |
| OleDbTransaction | Represents an SQL transaction to be made at a data source. This class cannot be inherited. |
Delegates
| Delegate | Description |
|---|---|
| OleDbInfoMessageEventHandler | Represents the method that will handle the InfoMessage event of an OleDbConnection. |
| OleDbRowUpdatedEventHandler | Represents the method that will handle the RowUpdated event of an OleDbDataAdapter. |
| OleDbRowUpdatingEventHandler | Represents the method that will handle the RowUpdating event of an OleDbDataAdapter. |
Enumerations
| Enumeration | Description |
|---|---|
| OleDbLiteral | Returns information about literals used in text commands, data values, and database objects. |
