Hi,

I'm using Open Acces 2014.2. on SQL Server 2012 SP2

When I performe the following LINQ query:

var result = db.Invoices.GroupBy(x => new {x.CreationTime.Date.Year, x.CreationTime.Date.Month}).Select(x => new { Month = x.Key.Month, Year = x.Key.Year }).ToList()

It produces the following sql query:

SELECT a.[CreationTime].[Year] AS  EXPR1, a.[CreationTime].[Month] AS  EXPR2 FROM [Invoices] a GROUP BY a.[CreationTime].[Year], a.[CreationTime].[Month]

That produces a Telerik.OpenAccess.RT.sql.SQLException: Cannot call methods on datetimeoffset.

Should it not generate a sql query like:

SELECT YEAR(a.[CreationTime]) AS  EXPR1, MONTH(a.[CreationTime]) AS  EXPR2 FROM [Invoices] a GROUP BY YEAR(a.[CreationTime]), MONTH(a.[CreationTime])

Here is the trace:

Hello Avri,

I will need to see if that is/why a regression. However, I think the solution is to use

var result = db.Invoices.GroupBy(x => new {x.CreationTime.Year, x.CreationTime.Month}).Select(x => new { Month = x.Key.Month, Year = x.Key.Year }).ToList();

So avoiding the .Date property should solve the issue.

Hi,

Sorry the initial post had a typo, the linq query should have been without the .Date

var result = db.Invoices.GroupBy(x => new {x.CreationTime.Year, x.CreationTime.Month}).Select(x => new { Month = x.Key.Month, Year = x.Key.Year }).ToList()

I tried several different linq query's and the one with .Date returned a sql query

SELECT YEAR(a.[CreationTime].[Date]) AS  EXPR1, MONTH(a.[CreationTime].[Date]) AS  EXPR2 FROM [Invoices] a GROUP BY YEAR(a.[CreationTime].[Date]), MONTH(a.[CreationTime].[Date])

Hi Arvi,

gotcha! The DateTimeOffset CLR type seems to be not handled properly yet. I filed a bug for this and in an upcoming version there will be handling for DateTimeOffset properties and methods.
You could switch to DateTime for the time being, this should avoid the issue.
Thanks for reporting this issue with us!

Thomas

Can you tell me if this is still a problem in the latest version of Telerik Data Access?  We are having a similar issue with a DateTimeOffset sql type/clr type column.

var result = from c in model.table
             group c by c.fieldstr into g
             select new objA {
                  key = g.fieldstr,
                  value = Max(g.datetimeoffsetValue)
             };

Hello Warren,

I tried with the latest version, and there is still some minor issue concerning the Max functionality.
However, you can work around it by using constructs similar to 

using Telerik.DataAccess;

var result =
    from c in model.table
    group c by c.fieldstr into g
    select new {
        key = g.Key,
        value = "{0}".SQL<DateTimeOffset>(g.Max(z => z.datetimeoffsetValue))
    };

The strange SQL extension method is needed because the Max function seems not to be handling the result type well (assumes Int16 instead of DateTimeOffset). I will file another bug for this. Until this is fixed, the SQL method ensures that the DateTimeOffset value is properly fetched from the server.

Thomas
