问题 We have installed the 32bit odp.net driver for Oracle. Our server currently hosts applications that are using the deprecated Microsoft Oracle driver.

(how to avoid conflicts with existing web applications?) 回答1: System.Data.OracleClient relies on the unmanaged Oracle client software in the same way that odp.net does: http://msdn

问题 I am using Code First EF with Oracle ODP.Net, and am trying to re-generate the Views via "EF Powertools Beta 3" within VS2012.

问题 I'm using ODP.NET (migrating from Microsoft's provider), and I have got stuck on a stored procedure that returns a refcursor. I have the following PL/SQL procedure (I have changed it a little bit to make it more general): PROCEDURE MyProc(parameter_no1 IN NUMBER, parameter_no2 IN NUMBER, RETCURSOR OUT ret_type) AS BEGIN OPEN RETCURSOR FOR SELECT ad.logo logo FROM tab_a a, tab_h h WHERE a.id IS NOT NULL AND a.h_id = h.id AND a.no1 = parameter_no1 AND a.no2= parameter_no2; END HanteraLogotype;

问题 I am trying to install Oracle Developer Tools for Visual Studio 2015 so that I can connect to a remote 11g database from SSRS/Visual Studio Projects in general, from my dev machine.

For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . For a .Net 4.0 application i'm using the OracleClient class from the ODP.Net 11 library. After a bit of research some people note that the ODP.net library can't handle the Windows newlines, but only the unix ones

问题 When I create a new .NET app with Oracle.DataAccess.dll, it works fine. However, I need to edit an existing web application with an older version of Oracle.DataAccess.dll installed, and when I try to run it locally, it throws our old friend, the "The provider is not compatible with the version of Oracle client" exception. The existing version on the app is 2.112.1.2. I have two versions available; 4.112.4.0 and 2.112.4.0. (The apps I create that work use 4.112.4.0.) The "obvious" answer would
