问题 I am trying to upgrade my existing application built on ODP.NET 11g to ODP.NET 12c in the hope that it'll improve performance of database calls and data retrieval. In this regard, I installed the latest ODP.NET 12c and changed all Oracle project references to point to the latest Oracle.ManagedDataAccess.dll instead of Oracle.DataAccess.dll . While the project builds successfully, I'm seeing an exception, "Unsupported column datatype" being thrown from the ExecuteReader method when trying to

问题 I'm attempting to call a procedure that takes a custom data type of table of numbers as one of the parameters. Here is the definition of the type: create type num_list as table of number; And the definition of the procedure: create or replace procedure my_procedure (listofnumbers num_list, v_value char) is begin update my_table set my_column = v_value where my_row_id in (select column_value from table(listofnumbers)); end; Using ODP.NET and C#, I'm declaring it as follows: var row_ids = new

问题 this is a follow-up to my previous question. I am trying to use ODP.net in Visual Studio 2015 to connect to a remote Oracle 11gr2 server. The specific reason is for SSRS reports. I have installed this version of ODT/ODAC, as recommended by Visual Studio: http://www.oracle.com/technetwork/topics/dotnet/whatsnew/vs2012welcome-1835382.html (for more info, please see my previous question). Without even opening up a solution, on the landing page of VS2015 I tried using the ODP.net driver by using

If cancellation is successful, an exception is thrown with the message of ORA-01013: user requested cancel of current operation. If the command executed in time without any errors, no exceptions are thrown. In a situation where multiple OracleCommand objects use the same

问题 We are in the process of moving from the .NET Microsoft oracle driver to the ODP.NET driver. One of the problems we have had is this error: ORA-12705: Cannot access NLS data files or invalid environment specified We were able to stop the error by modifying the registry and changing the setting (see this question) In our case we changed HKEY_LOCAL_MACHINE - SOFTWARE - ORACLE - NLS_LANG which was set to NA to be the same as HKEY_LOCAL_MACHINE - SOFTWARE - ORACLE - HOME0 - NLS_LANG which was set
