Problems with OracleDataReader

Post by alexB » Wed 18 Apr 2012 12:44

Hello,

I found that a bug was introduced with one of your previous releases, I don't know which one exactly but I can confirm that all was working fine in build version 6.60.258.

When OracleDataReader.GetSchemaTable() is called, an "Object reference not set to an instance of an object" error is thrown.

An example of OracleCommand.CommandText that can be used to reproduce the bug is

Code: Select all

select * from emp e, emp m where e.MANAGER_ID = m.EMPLOYEE_ID

My Oracle: Oracle Database 10g Express Edition Release 10.2.0.1.0 - Product

We have fixed the bug with NullReferenceException in the OracleDataReader.GetSchemaTable() method. We will notify you when the corresponding build of dotConnect for Oracle is available for download.
