2009-07-24  Veerapuram Varadhan  <[email protected]>
	
	* DbCommandBuilder.cs (CreateDeleteCommand, CreateUpdateCommand): Add the 
	nullcheck-param into the respective command's parameter list.  Fixes 
	build breaks.  Individual provider's CommandBuilder classes from 2.0 
	profile onwards use the base version of methods to maintain these commands.
	(Get*Command): Cleanup code duplication
	* DbDataAdapter (Update): Use SourceColumnNullMapping property to handle 
	nullcheckparams.  Fixes #522624.  Patch by 
	Gert Driesen  <[email protected]>.

2008-12-30  Gert Driesen  <[email protected]>

	* DbCommandBuilder.cs: When CatalogSeparator or SchemaSeparator are
	not set (or explicitly set to null or empty string), then return
	default separator character. Added value check for CatalogLocation and
	ConflictOption. Removed regions.

2008-12-30  Gert Driesen  <[email protected]>

	* DbCommandBuilder.cs: Fixed default value for ConflicOption.

2008-12-30  Gert Driesen  <[email protected]>

	* DbCommandBuilder.cs: Return a zero-length string when QuotePrefix or
	QuoteSuffix are not set (or are set to null). Changing QuotePrefix or
	QuoteSuffix after a command has been generated should result in an
	InvalidOperationException.
	* DbConnectionStringBuilder.cs: Added support for ODBC rules. Major
	rewrite fixing many compatibility issues, and improving support for
	connectionstring formats/characters.

2008-11-25  Atsushi Enomoto  <[email protected]>

	* 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.

2008-10-07  Daniel Morgan  <[email protected]>

	* 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]>

	* DataContainer.cs (*.ZeroOut): Rename from the somewhat unclear

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]>

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

	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
