Bug #: 50000957 (SQL Hotfix)



SYMPTOMS
Consider the following scenario. You develop a project by using Microsoft Visual Studio 2005. You try to use the OdbcCommandBuilder class to update a Sybase database in the Microsoft .NET Framework 2.0. In this scenario, you receive the following error message:

InvalidOperationException - Dynamic SQL generation is not supported against a SelectCommand that does not return any base table information.

Note This problem occurs when you use the Sybase ODBC driver to connect to the database.



CAUSE
This issue occurs if the following conditions are true:
 * The driver that you use to connect to the database does not support the SQLColAttribute(SQL_DESC_BASE_TABLE_NAME) function. The driver will return an empty string when it uses this function.
 * The driver returns a blank character (&quot; &quot;) when the driver uses the SQLGetInfo(SQL_IDENTIFIER_QUOTE_CHAR) function.
