	used to indicate whether the type of the parameter has been updated.
	Changed signature of 'updated' argument in GetFrameworkValue to ref
	to match delegate in Mono.Data.Tds, and convert value if either the
	type has been changed or if the 'updated' argument is true (which -
	for now - means the value or size changed in TdsMetaParameter).
	Various fixes for derived parameters:
	- parameter_type 2 means InputOutput parameter, while 3 means Output;

	- When type has variable size, then also set Size.

2009-01-04  Gert Driesen  <[email protected]>

	unnecessary initializations. Added missing reader state
	and row state checks. Fixed implementation of HasRows.
	Modified type of DataType to object on 1.0 profile for
	compatibility with .NET 1.x. Do not mark (Big)VarBinary
	or ((Big)Binary as long, as unit tests show that IsLong
	is for wide (unicode) data types. Fixed type data for
	SmallDateTime and SmallMoney data types. Improved support
	for bigint data type (using TDS 7.0).

2009-01-03  Gert Driesen  <[email protected]>

	* SqlCommand.cs: Moved connection reset before the throw.
	Improved exception message.

2009-01-03  Gert Driesen  <[email protected]>

	parameters on the 2.0 profile, and set SourceVersion to
	Current on 1.0 profile. Changed accessibility of RefreshSchema
	to public, and do not immediately create commands. Removed
	CWL.

2009-01-03  Gert Driesen  <[email protected]>

	* SqlParameter.cs: When setting ParameterName or sourceName to
	null, use a zero-length string instead. On 1.0 profile, only
	infer type from value if value is not null or DBNull. Store
	raw value in TdsMetadataParameter, and use delegate to convert
	it to framework type (when necessary). Improve implementation
	of SqlValue (still needs lots of work).

2009-01-03  Gert Driesen  <[email protected]>

	* SqlCommandBuilder.cs: Added missing checks for QuotePrefix and
	QuoteSuffix on 2.0 profile, and return a zero-length string if
	not set (or set to null) on 1.0 profile. Do not allow the value
	of CatalogSeparator and SchemaSeparator to be changed from '.'.
	Modified generated SQL to match MS. Added implementation for
	QuoteIdenfifier. Modified parameters to match MS.
	* SqlParameter.cs (SqlValue): Keep Value in sync.

	the previous patch...

2008-12-20 Gonzalo Paniagua Javier <[email protected]>

	* SqlConnection.cs: close the connection on error.

2008-12-16 Gonzalo Paniagua Javier <[email protected]>

	* SqlParameter.cs: don't allocate error strings until the error
	actually happens. Compare types instead of strings. Use a Hashtable
	for type mappings.

2008-12-12 Gonzalo Paniagua Javier <[email protected]>

	* SqlParameter.cs: use the underlying type when inferring the type for
	enumerations.

2008-11-13  Veerapuram Varadhan  <[email protected]>

	* SqlCommand.cs: When a timeout exception occurs, reset the
	connection before re-using it.  Fixes connection corrupted errors
	on timeout exception.
	
2008-11-09  Gert Driesen  <[email protected]>

	* SqlConnection.cs (ClearPool): Added null check.

2008-11-09  Gert Driesen  <[email protected]>

	* SqlConnection.cs: In Close, also remove reference to pool. In Open,
	set TdsConnection.Pooling to false for a non-pooled connection.
	Fixed ClearAllPools to no longer create a new connection for each
	pool. In ClearPool, perform a lookup of the pool to clear using
	the connectionstring as the pool field may refer to another pool
	(as the connectionstring may have changed).

2008-09-30  Veerapuram Varadhan  <[email protected]>

	* SqlDataReader.cs (GetSqlXml): Handle the scenario when Sql
	Server 2005 returns Xml column type as NTEXT when called from

	* SqlDependency.cs : wrong namespace.

2008-08-14  Gert Driesen  <[email protected]>

	* SqlConnection.cs: Use constants for min/max values. When value is
	zero-length string, then fallback to default value for boolean and
	integer backed properties. Throw ArgumentException when min pool size
	exceeds max pool size. Check whether value for 'MARS' is a bool.
	The 'user instance' property is 2.0 only.

2008-08-14  Gert Driesen  <[email protected]>

	* SqlConnection.cs: Convert keywords to lowercase instead of uppercase
	to avoid further case changes in exception messages.

	parameters are added. Added check to see if transaction is
	associated with same connection as the command and updated
	exception messages.

2008-07-28  Gert Driesen  <[email protected]>

	* SqlCommand.cs: Added bool argument to ValidateCommand to specify
	whether an async method is being executed. Minor changes to exception

	* SqlCommand.cs: Avoid NRE in CloseDataReader when connection is NULL.
	Fixes bug #412584. Removed unused moreResults eargument from
	CloseDataReader. Removed behavior argument from Execute, and have it
	use the behavior field instead. In ValidateCommand, throw

	change.

	instead set it to null in Transaction when transaction is no longer
	open.

2008-07-28  Gert Driesen  <[email protected]>

	* SqlConnection.cs: Use null as default value for connectionString
	field. Remove Init method, as initialization is done in
	SetDefaultConnectionParameters. Initialize parms in
	SetDefaultConnectionParameters to avoid calling Reset on newly
	initialized collection. In Dispose (bool), also invoke base.Dispose if
	SqlConnection was already disposed. Fixes bug #412571. 

2008-07-28  Gert Driesen  <[email protected]>

	* SqlConnection.cs (ChangeState): Return immediately when new state
	equals original state. Fixes bug #412574. Removed extra whitespace.

	array to be GCed along with schemaTable.
	
2008-07-23  Veerapuram Varadhan  <[email protected]>

	* SqlParameterCollection.cs: this [int] must check the range and
	throw an exception if necessary.
	
	* SqlCommand.cs: throw IOEX when stored procedure is not found in
	DeriveParameters. All procedures in MS SQL will report at least
	one parameter - the return value.

	On 2.0 profile, ignore call to Rollback when transaction was already
	disposed.

2007-10-18  Gert Driesen  <[email protected]>

	* SqlConnection.cs: Avoid unnecessary initialization. Use string.Empty
	for assigning zero-length string, and use String.Length to check for

	Added StructuredTypeMembers schema collection and restrictions. Fixed
	table name for MetaDataCollections collection. Implemented
	DataSourceInformation collection. Added missing data types (probably
	introduced in 2.0 SP1). In GetSchema, throw InvalidOperationException
	if connection is closed and throw NotImplementedException for
	StructuredTypeMembers collection.

2007-10-18  Gert Driesen  <[email protected]>

	* SqlConnection.cs: On 1.0 profile, IsolationLevel.Unspecified is
	not valid. On 2.0 profile, when IsolationLevel.Unspecified is passed
	make sure to also set SqlTransaction.IsolationLevel to
	ReadCommitted. Modified exceptions to match MS.

2007-10-17  Nagappan <[email protected]> 

	* SqlParameter.cs (ConvertToFrameworkType): Added SqlDbType.Image.

2007-10-17  Nagappan <[email protected]>

	* SqlCommand.cs (ExecuteNonQuery): Return
	Connection.Tds.RecordsAffected if it is successful.  Patch from
	Jörg Rosenkranz <[email protected]>.

	* SqlConnectionPool.cs (ReleaseConnection): A patch from Joerg
	Rosenkranz <[email protected]>. Currently, if a connection is
	closed by an external event (network problem, etc.) it is pushed
	back into the connection pool. The next Open call retrieves this
	invalid connection which leads to exceptions when executing
	statements.

	This patch fixes this problem. This closes bug #47429.

2003-02-16  Daniel Morgan <[email protected]>

	* ChangeLog: added this file

	* SqlConnection.cs: - parse data source for 3 possible uses:
	"Server=hostname", 
	"Server=hostname\\instancename", 
	"Server=hostname,port" and open the connection based on the
	resulting server name and port.  
	- Added support for named instances
	by discovery of the sql server tcp port via the sql monitor (udp port 1434)
	thanks to Phillip Jerkins ([email protected]) contribution.
	Also, thanks to Gonzalo and Tim for their help with timeouts.
