2006-05-31  Gert Driesen  <[email protected]>

	* OdbcErrorCollection.cs: Removed explicit interface implementation

	This fixes the build on Windows (using csc).

2005-08-09  Sureshkumar T  <[email protected]>

	* OdbcDataReader.cs: GetSchemaTable (): set values for the column
	attributes using SQLColAttribute. If SQLPrimaryKeys does not

	if the command is prepared.

	* OdbcConnection.cs: Open (): set disposed to false so that close
	will be called in Dispose.

	for GetString, otherwise, it creates a string of length 255. Use
	ArrayList for keys as the columns are different from the selected
	columns. fixes bug #75263.

2005-06-09  Sureshkumar T  <[email protected]>

	* 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
	database anyway, provides NUMERIC datatype as DECIMAL.

2005-05-31  Sureshkumar T  <[email protected]>

	* OdbcParameter.cs: setBuffer (): for numeric type, the buffer
	parameter should be a packed decimal struct. fixes bug #75041.

2005-04-05  Sureshkumar T  <[email protected]>

	- GetValue: Decode only outsize length for SQL_C_TYPE.CHAR type in
	SQLGetData.

2005-03-11  Sureshkumar T  <[email protected]>

	uses base class's OnStateChange handler.

2005-03-10  Sureshkumar T  <[email protected]>

	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  <[email protected]>

	* 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.

2005-02-04  Sureshkumar T  <[email protected]>
	    Appasamy <[email protected]>

	* OdbcConnection.cs: Implemented properties database, datasource,

	GetValue.  fixes bug #71173.

	* OdbcType.cs: Change enum values for compatiability with MS.NET.
	* libodbc.cs: Change enum values for compatiability with

	<[email protected]>.

2005-01-13  Sureshkumar T  <[email protected]>

	* OdbcDataReader.cs: Implement NextResultSet for multiple result
	set queries.

	then for each Next result set. Thanks to
	[email protected] (Sebastien Robitaille) for
	pointing out this optimization (bugzilla #70530).

	* libodbc.cs: Added library calls SQLFreeStmt and SQLMoreResults
	for mutiple resultsets.

2005-01-10  Sureshkumar T  <[email protected]>

	* OdbcDataReader.cs: Connection has to be closed only after
	Statement handle is freed. fixes bug #70048.

2005-01-07  Sureshkumar T  <[email protected]>

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

	* OdbcType.cs: Added a new enum for Odbc C DataTypes. This should
	essentially be passed to drivers, since the public OdbcType types
	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.

2004-12-28  Duncan Mak  <[email protected]>

	* 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.)

	This fixes #70727.
