The System.Data.OleDb namespace is the.NET Framework Data Provider for OLE DB.
Classes
| OleDbCommand |
Represents an SQL statement or stored procedure to execute against a data source. |
| 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. |
| OleDbConnection |
Represents an open connection to a data source. |
| OleDbConnectionStringBuilder |
Provides a simple way to create and manage the contents of connection strings used by the OleDbConnection class. |
| 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. |
| OleDbEnumerator |
Provides a mechanism for enumerating all available OLE DB providers within the local network. |
| OleDbError |
Collects information relevant to a warning or error returned by the data source. |
| 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. |
| OleDbFactory |
Represents a set of methods for creating instances of the OLEDB provider's implementation of the data source classes. |
| OleDbInfoMessageEventArgs |
Provides data for the InfoMessage event. This class cannot be inherited. |
| OleDbMetaDataCollectionNames |
Provides a list of constants for use with the GetSchema method to retrieve metadata collections. |
| 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. |
| 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 make sure that a user has a security level sufficient 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(Guid, Object[]) method. |
| OleDbTransaction |
Represents an SQL transaction to be made at a data source. This class cannot be inherited. |
Enums
| OleDbLiteral |
Returns information about literals used in text commands, data values, and database objects. |
| OleDbType |
Specifies the data type of a field, a property, for use in an OleDbParameter. |
Delegates
| 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. |
Remarks
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.
