we're using the entity framework 4.1 and devart with oracle.
Recently we tried to update our devart provider from version 6.10.126 to 6.5.
After that update we receive the "ORA-12704: character set mismatch" exception in some situations.
Our datamodel is a little more complex and contains at maximum a three level deep inheritance. I tried to reduce its complexity as far as possible but it's still too complex to explain in detail. I can send you my sample project which causes that bug.
The bug occurs, when I execute the following statement:
Code: Select all
var foreigners = (from s in storage.Person.OfType() select s).ToList();Code: Select all
SELECT
1 AS C1,
CASE WHEN (("Project1".C1 = 1) AND ("Project1".C1 IS NOT NULL)) AND ( NOT (("UnionAll2".C3 = 1) AND ("UnionAll2".C3 IS NOT NULL))) THEN '0X0X0X' WHEN ("UnionAll2".C2 = 1) AND ("UnionAll2".C2 IS NOT NULL) THEN '0X1X' WHEN ("UnionAll2".C3 = 1) AND ("UnionAll2".C3 IS NOT NULL) THEN '0X0X0X0X' ELSE '0X2X0X' END AS C2,
