CUBRID OLEDB Driver 9.1.0 Release Note

Updates summary since beta release
=================================================

• 2 new schema rowsets added (Catalog and SQL language)
• New test cases added (localization, data types handling, extended connect)
• Changed the login internal procedure to use the connect_with_url CCI function; additional parameters included (login & query timeout, auto-commit)
• 64-bit driver library available for download
• Various updates in the source code; more code cleanup
• Additional resources made available (new tutorial and short video)
• Some improvements in LOB handling

General development notes
=================================================

• The 8.4.1 provider code is based on the legacy CUBRID 3.1 OLE DB provider code
• Various enhancements and support for latest CUBRID releases has been implemented
• We have focused on supporting OLE DB Consumer templates (http://msdn.microsoft.com/en-us/library/8k76sd16%28v=vs.80%29.aspx). Direct OLE DB interfaces should work as well, but the technology is deprecated. 
• A full suite of open source test cases is now part of the driver code base release
• Regarding .NET support (via System.Data.OleDb namespace), we are encouraging the use of the fully managed CUBRID ADO.NET driver instead (http://www.cubrid.org/wiki_apis/entry/cubrid-ado-net-driver).
• The code is released under the BSD license (http://www.cubrid.org/bsd_license).

Release components

Known limitations

• There is no full support yet for BLOB/BLOB Dynamic Accessors
• Update() support is restricted to Auto-Commit mode = Off, which must be explicitly stated via session transaction.
• Not all schema are implemented as defined here: http://msdn.microsoft.com/en-us/library/a6fhbff0%28v=vs.71%29.aspx.
• More test coverage is required for testing non-standard data types
• We are supporting mainly C++ OLE DB templates; there is limited or no support for other driver usages (direct interfaces
• Very limited support for some special data types: SET, MUTISET and SEQUENCE

What's next/To-Do
=================================================

• Re-Generate and publish the Doxygen driver documentation
• Continue to improve support for BLOB/CLOB
