	rewrite fixing many compatibility issues, and improving support for
	connectionstring formats/characters.

	* DbEnumerator.cs : use above.

2008-11-17  Raja R Harinath  <[email protected]>

	Avoid allocating empty arrays.
	* Index.cs (empty): New empty array constant.
	(Reset): Initialize '_array' to 'empty'.

	* Index.cs: Remove use of Array and Size properties by taking
	advantage of the invariant that _array is never null.

	* RecordCache.cs: Reduce some extraneous nesting.

	* DbConnectionStringBuilder.cs: fix setting and getting
	the ConnectionString property

2008-09-16  Veerapuram Varadhan  <[email protected]>

	** Fixes#421336 - Patch provided by <[email protected]> 	
	DbCommandBuilder.cs: Several scenarios leading to exceptions when
	creating the update, insert and delete commands: 

	1. The "IsExpression" column in the column schema table can also
	be DBNull which is equivalent to "false" but the DBCommandBuilder
	does not check for DBNull and simply tries to cast it into a bool,
	which will fail.

	2. The commands do not get refreshed after a call to
	UpdateSchema() because they are not set to NULL. This has the
	consequence that empty commands(created with CreateNewCommand())
	are returned afterwards.

	3. Multiple parameters with the same name are generated if the
	parameter names should be named after the columns.
	
2008-09-05  Raja R Harinath  <[email protected]>

2003-11-10  Pedro Martínez Juliá  <[email protected]>

	exception there.

2003-10-22  Eran Domb  <[email protected]>

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

2003-08-26  Gonzalo Paniagua Javier <[email protected]>

	when accessing the data.

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

	* DbDataAdapter.cs: BuildSchema now uses ColumnName instead
	of BaseColumnName (bug #39830) for DataColumn names.
	BaseTableName is no longer taken into account as well.

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.
	Fixed error when there is no ColumnMapping at all.
	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
	patch.

2003-01-08  Gonzalo Paniagua Javier <[email protected]>

	* DbDataRecord.cs: return DbNull.Value in GetValue () if value is null.
