	* DbDataAdapter.cs:
		Ensure correct order for LoadDataRow
		Fixing schema creation
		Use NewRowArray API

	record is not already disposed. i.e. to make sure later the same
	record is not reused. Implemented a static method to compare two
	version of records in a container.

	* DataAdapter.cs: Implemenetd OnFillError handler.

2005-03-22  Sureshkumar T  <[email protected]>

	* DbDataAdapter.cs: Update (): update the rows based on the
	UpdateRowSource property. Process further based on the
	RowUpdatedEvent handler argument's Status property.
	Fixes bug #73587. Thanks to [email protected] (Ingo Bauersachs) for
	bug report and patch.

	default error.

2005-03-01  Sureshkumar T  <[email protected]>

	* DbDataAdapter.cs (Update ()) :
	- Check for one return result set and map the values back to
	  datatable.
	- Check for output & return value parameters and update the value
	  back to mapped column

2003-09-21  eran <[email protected]>

	* DbDataRecord.cs: The method
	System.Data.Common.DbDataRecord.GetValues(object[] values) did not
	put the values of the DbDataRecord into values parameter.

2003-03-17  Aleksey Demakov <[email protected]>

2003-02-28  Aleksey Demakov <[email protected]>

	* DbDataAdapter.cs: Update (DataSet) updates the default
	table only.

2003-02-25  Alan Tam <[email protected]>
	
	* DbDataAdapter.cs: Added support for filling when schema is present.
	Fixed incorrect behavior when ColumnMapping is present
	when more than one fields have the same name. Implemented Dispose.

	Still have some problems in finding the correct TableMapping
	because the SourceTable name is not present in BuildSchema

2003-02-24  Aleksey Demakov <[email protected]>

	* DbDataAdapter.cs: The original code might pass a null DataTableMapping
	value which is then used to create a RowUpdatingEventArgs
	instance. So RowUpdatingEvent handler (for instance
	CommandBuilder) could get null DataTableMapping which
	might be unexpected. The patch makes sure that a non-null
	DataTableMapping is passed.

2003-01-26  Gonzalo Paniagua Javier <[email protected]>

	* DbEnumerator.cs: why does the runtime throw an invalid cast here? The
	object is an Int16... Gotta fill a bug report and when fixed undo this
