The program EF model has an association with a table with the following schema: create table test_time_hs ( id serial not null , name char(50), creation_time datetime hour to second, primary key (id) ); The program retrieves one row of data from the table test_time_hs (C# code , "db" being the name of the EF model ): test_time_hs myData; myData = db.test_time_hs.FirstOrDefault<test_time_hs>(); updates the value for the field "creation_time", which in the program will appears as having .NET type "Time" : myData.creation_time = new TimeSpan(DateTime.Now.Ticks); and then pushes back the updates to the database calling db.SaveChanges(); This action will raise an exception. where the last nested exception has the description Unknown PrimitiveTypeKind Time and the top of the stack is: IBM.Data.DB2.Entity.MetadataHelpers.GetDbType IBM.Data.DB2.Entity.DmlSqlGenerator.ExpressionTranslator.CreateP arameter IBM.Data.DB2.Entity.DmlSqlGenerator.ExpressionTranslator.Visit System.Data.Common.CommandTrees.DbConstantExpression.Accept (...) | |
