My entity objects all line up to the DB objects. I found only a single reference to this error via Google: http://ramonaeid.spaces.live.com/blog/cns!A77704F1DB999BB0!182.entry After reading this, I remember that we did add 2 fields and then updated the entity model from VS 2010. I'm not sure what he means by "hand coding" the differences. I don't see any. All I'm doing in code is populating the entity object and then saving. (I also populate the new fields in code) I populated the date field with DateTime.Now.. The important part of the code is this: ctx.SaveChanges(SaveOptions.AcceptAllChangesAfterSave); The database is SQL Server 2008. Thoughts?

Now it doesn't anymore. Here is the code: var itemMember = Db.Members.FirstOrDefault(p => p.Id == CurrentMember.Id); var itemSelectedName = Db.Topics.FirstOrDefault(p => p.Id == TopicId); var itemMap = Db.Reeves.FirstOrDefault(p=> p.Member.Id == CurrentMember.Id); var itemReeve = Db.Reeves.FirstOrDefault(p => p.Member.Id == CurrentMember.Id); var item = new Problem { Name = input.Name, Text = input.Info, Topic = itemSelectedName, WhoIs = itemMember, Province = itemMap.Province, District = itemMap.District, Town = itemMap.Town, Reeve=itemReeve, Created=DateTime.Now, Solved = false, Read=false }; Db.Problems.Add(item); Db.SaveChanges(); There is nothing null in the code and it throws an error: The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value. What should I do ?

a datetime2 data type to a datetime data type resulted in an out-of-range value 7 Comments 09 April 2014 13:45 4.43 (7 votes) Entity Framework I managed to generate this error http://www.mikesdotnetting.com/article/229/conversion-of-a-datetime2-data-type-to-a-datetime-data-type-resulted-in-an-out-of-range-value twice within a few days while working with the Entity Framework and SQL Server 2012. I had to resort to searching for a resolution on both occasions so I'm posting about it to https://scottstoecker.wordpress.com/2014/01/24/conversion-of-a-datetime2-data-type-to-a-datetime-error-in-entity-framework/ sear the cause and solution into my brain. First, note the exception type. It is a SqlException, so it's being generated by the SqlClient provider. In other words, this is your database entity framework talking. The SQL Server datetime datatype is capable of storing dates in the range 1753-01-01 to 9999-12-31, or Jan 1st 1753 to way longer than anyone reading this needs to worry about. The datetime2 data type was introduced in SQL Server 2008. The range of dates that it is capable of storing is 0001-01-01 to 9999-12-31, or Jan 1st 1 AD to way longer than anyone datetime2 to datetime reading this.... You get the idea. The .Net datetime is isomorphic with the SQL Server datetime2 type - the range of possible values is the same. The default value for an uninitialised datetime variable is DateTime.MinValue, or 0001-01-01. And this is usually the cause of the error message featured in the title of this post. It happens when you do not provide a value for a datetime in your C# (or VB) code which is to be stored in a non-nullable datetime field in the database. The .Net variable or property will default to 0001-01-01 which SQL Server will see as a valid value for a datetime2 field, but then tries to convert to a datetime type to store it in the appropriate field in the database table. As has already been established, 0001-01-01 is outside of the range of acceptable values for a datetime field. Hence the error message. So what are the possible fixes? Actually, there are a few: 1. Change the storage to DateTime2 in the database. Datetime2 is the recommended type for dates and times in SQL Server 2008 onwards. You will need to explictly map the relevant columns to
"Conversion of a datetime2 data type to a datetime" error in EntityFramework I was following the very helpful tutorial at http://msdn.microsoft.com/en-us/data/jj206878, taking my first crack at Entity Framework. Yes, I'm more than a little behind the curve on that technology. But, no time like the present to catch up. To be honest, I was "mostly following" the tutorial. I went off and created my own User table, the script of which is: CREATE TABLE [dbo].[User] ( [Id] INT IDENTITY (1, 1) NOT NULL, [FirstName] VARCHAR (50) NOT NULL, [LastName] VARCHAR (50) NOT NULL, [Email] VARCHAR (100) NOT NULL, [Password] VARCHAR (50) NOT NULL, [CreatedDate] DATETIME DEFAULT (getdate()) NOT NULL, PRIMARY KEY CLUSTERED ([Id] ASC) ); And I continued to mostly follow along with the tutorial, generating the various EF classes, and wrote code to insert values into the database using the wonderful EF stuff: protected void Button1_Click(object sender, EventArgs e) { using (var db = new Entries()) { var newUser = new User { FirstName = txt1.Text, LastName = txt2.Text, Email = txt3.Text, Password = txt4.Text }; db.Users.Add(newUser); db.SaveChanges(); var queryUsers = from u in db.Users orderby u.LastName select u; foreach (var item in queryUsers) { Response.Write("
User = " + item.FirstName + " " + item.LastName); }
