System.Data.OleDb Namespace

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 that you can use to query and update the data source.

For information about how to use this namespace, see the OleDbDataAdapter, OleDbDataReader, OleDbCommand, and OleDbConnection classes.

Public class OleDbCommand Represents an SQL statement or stored procedure to execute against a data source.
Public class OleDbCommandBuilder Automatically generates single-table commands that are used to reconcile changes made to a DataSet with the associated database. This class cannot be inherited.
Public class OleDbConnection Represents an open connection to a data source.
Public class OleDbConnectionStringBuilder Provides a simple way to create and manage the contents of connection strings used by the OleDbConnection class.
Public class OleDbDataAdapter Represents a set of data commands and a database connection that are used to fill the DataSet and update the data source.
Public class OleDbDataReader Provides a way of reading a forward-only stream of data rows from a data source. This class cannot be inherited.
Public class OleDbEnumerator Provides a mechanism for enumerating all available OLE DB providers within the local network.
Public class OleDbError Collects information relevant to a warning or error returned by the data source.
Public class OleDbErrorCollection Collects all errors generated by the .NET Framework Data Provider for OLE DB. This class cannot be inherited.
Public class 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.
Public class OleDbFactory Represents a set of methods for creating instances of the OLEDB provider's implementation of the data source classes.
Public class OleDbInfoMessageEventArgs Provides data for the InfoMessage event. This class cannot be inherited.
Public class OleDbMetaDataCollectionNames Provides a list of constants for use with the GetSchema method to retrieve metadata collections.
Public class OleDbMetaDataColumnNames Provides static values that are used for the column names in the OleDbMetaDataCollectionNames objects contained in the DataTable. The DataTable is created by the GetSchema method.
Public class OleDbParameter Represents a parameter to an OleDbCommand and optionally its mapping to a DataSet column. This class cannot be inherited.
Public class OleDbParameterCollection Represents a collection of parameters relevant to an OleDbCommand as well as their respective mappings to columns in a DataSet.
Public class OleDbPermission Enables the .NET Framework Data Provider for OLE DB to help make sure that a user has a security level sufficient to access an OLE DB data source.
Public class OleDbPermissionAttribute Associates a security action with a custom security attribute.
Public class OleDbRowUpdatedEventArgs Provides data for the RowUpdated event.
Public class OleDbRowUpdatingEventArgs Provides data for the RowUpdating event.
Public class OleDbSchemaGuid Returns the type of schema table specified by the GetOleDbSchemaTable method.
Public class OleDbTransaction Represents an SQL transaction to be made at a data source. This class cannot be inherited.
  Delegate Description
Public delegate OleDbInfoMessageEventHandler Represents the method that will handle the InfoMessage event of an OleDbConnection.
Public delegate OleDbRowUpdatedEventHandler Represents the method that will handle the RowUpdated event of an OleDbDataAdapter.
Public delegate OleDbRowUpdatingEventHandler Represents the method that will handle the RowUpdating event of an OleDbDataAdapter.
  Enumeration Description
