 Test Case

+With the test case provided in the previous comment, you will get 
+incorrect values when reading them back from the database.
+With my application, I also have the following exception (which I 
+was not able to reproduce with the test case, but is related to the 
+same problem):
+System.OverflowException: Number overflow.
+in <0x00145> Mono.Data.Tds.Protocol.Tds:GetDecimalValue (byte,byte)

+This exception cannot be reproduced anymore if the patch provided in 
+the bug description is applied to Tds.cs.
