I am using linqtosql and inside of linq query, I tried to convert datetime type column to string like 'dd-MM-yy'. However, I got error as following :

NotSupportedException: Method 'System.String ToString(System.String)' has no supported translation to SQL.

following is my linq query :

from ffv in Flo_flowsheet_values
where ffv.Flowsheet_key == 2489
&& ffv.Variable_key == 70010558
&& ffv.Status == 'A'
&& ffv.Column_time >= DateTime.ParseExact("2010-06-13 00:00", "yyyy-MM-dd HH:mm", null)
&& ffv.Column_time <= DateTime.ParseExact("2010-06-13 22:59", "yyyy-MM-dd HH:mm", null)
select new  { 
ColumnTime = ffv.Column_time
,ColumnTimeForXCategory = ffv.Column_time.Value.ToString("dd-MM-yy") ***====> this statement invoke error***
,BTValue = Convert.ToDouble( ffv.Value) }

what is problem?

Thanks in advance

Many to many mappings aren’t transparent in LINQ to SQL and it maps the link table the same way the SQL schema has it when creating one. In other words LINQ to SQL isn’t smart about many to many mappings… >>> More
