2005-06-09  Sureshkumar T  <tsureshkumar@novell.com>

	* OdbcDataReader.cs: GetValue (): return decimal in case of odbc
	type Numeric. Move the temp buffer logic inside.

	* OdbcTypeConverter.cs: map SQL_TYPE.NUMERIC to SQL_C_TYPE.CHAR by
	now, since PgSql driver seems not to accept NUMERIC c type. Other

2005-03-10  Sureshkumar T  <tsureshkumar@novell.com>

	Migrated core classes to derive from ProviderBase instead of
	implementing IDb* interfaces. Most part of these files have been
	branched with #if NET_2_0/ONLY_1_1. Make sure any changes works
	with both the profiles.

	* OdbcFactory.cs: Concrete Factory for DbProviderFactory. Factory
	to generate Connection,Command,etc.

	* OdbcConnectionFactory.cs: Concrete factory for DbConnectionFactory.

	* OdbcTransaction.cs: migration and overrides.
	* OdbcCommandBuilder.cs: migration and overrides.
	* OdbcDataReader.cs: --do--. no command behavior member as it will
	be maintained in base provider class.
	* OdbcParameterCollection.cs: --do--. Now, local ArrayList is not
	maintained here, instead it is in base class. Most of the methods
	which operated on this list are not needed in NET_2_0.
	* OdbcConnection.cs: Migration. connectionString is maintained in
	DbConnectionBase class.
	* OdbcParameter.cs: Migration. Many of the local members like
	value,sourceColumn are maintained in DbParameterBase.
	* OdbcCommand.cs: Migration. commandText,timeout and
	commandTimeOut are maintained in DbCommandBase class.

2005-03-10  Sureshkumar T  <tsureshkumar@novell.com>

	* OdbcType.cs: Added enums for SQL_TYPE & SQL_C_TYPE.
	
	* libodbc.cs: Accept SQL_C_TYPE for driver
	parameters. SQLBindParameter takes two parameters SQL_TYPE and
	SQL_C_TYPE. This caused the whole lot of changes done in this
	revision.
	
	* OdbcParameter.cs: Set default values of OdbcType & DbType. Pass
	mapped SQL_TYPE and SQL_C_TYPE to SQLBindParameter. Increase
	buffer size by 2 for additional ' chars.
	
	* OdbcTypeConverter.cs: Added class to convert between OdbcType,
	SQL_TYPE, SQL_C_TYPE.
	
	* OdbcColumn.cs: Added private members for SQL_TYPE and
	SQL_C_TYPE. conversion from/to odbctype to/from SQL_TYPE is done
	through OdbcTypeConverter class.
	
	* OdbcDataReader.cs: use OdbcColumn's SQL_C_TYPE member. It keeps
	track of default mapping between odbctype, SQL_TYPE and
	SQL_C_TYPE. Move dataTableSchema.AcceptChanges inside if condition
	to avoid null reference exception.

	* OdbcDataReader.cs: Pass OdbcCType.SignedBigInt for accessing big

	differs from types expected in drivers in some cases.

	* libodbc.cs : Added a ODBC method which takes OdbcCType
	enumeration for SQLGetData for BigInt fields.

	fixes bug #65342.

	* libodbc.cs: Change all the DllImport attributes to point to
	"odbc32.dll" instead of "odbc32", because /etc/mono/config lists
	"odbc32.dll" (all other entries in the file have the .dll suffix
	as well, for consistency's sake, let's rename it here.)
