Hi,

I get the following exception while reading a Date field from Oracle. What can I do with this?

Please provide us with the DDL and DML script of your table(s).
Also please send us some piece of the code you use for reading data or a small test project.

Hi,

I use Entity Framweork:




















































Hier is how do I read the data:

Model.Entities ent = new Model.Entities(connStr);
var o2 = (from e in ent.PERSON select e).First();
Console.WriteLine(o2.SYSPERSON);

Regards,
Mak

Sorry, but that is not enough. Please provide us with data you are trying to get from the server (in form "INSERT INTO PERSON VALUES (sysperson, identam)"). Also please tell us your Oracle version.

Getting this when trying to use the Entity Framework under Visual studio 2008
I'm using Dot Connect 5.6.0 Pro
