APPLIES TO

  • Microsoft .NET Framework 2.0



Bug: #50000940 (SQL Hotfix)

SYMPTOMS

Consider the following scenario. You develop a Microsoft .NET Framework 2.0-based application by using Microsoft Visual Studio 2005. In the application, you use the .NET Oracle data provider to connect to an Oracle 9i database or an Oracle 10g database. In the database, there is a table that stores an XML file in a long raw column. The size of the XML file is bigger than 8 KB. You use the OracleDataReader.GetBytes method to read the long raw column into an XML file. In this scenario, incorrect data is written to the file. Therefore, some parts of the XML file cannot be parsed.

CAUSE

The XML file is stored in chunks. A chunk is a page that has a size of 8 KB. When the method reads the data, the OracleDataReader object will read the long raw data in chunks. If the size of the data is bigger than 8 KB, the object has to read more than one chunk. Because each chunk has 8 bytes of header information at the beginning, the object incorrectly returns the header information as raw data.

RESOLUTION
