I've created two columns in sql table that one is a identity column and another one is a varchar column. I need to generate identity column starting from the value 1000. I had tried the below code snippet, but it was given error "An error occurred while updating the entries. See the inner exception for details.."
Place objPlace = new Place(); objPlace.PNAME = "place 3"; //objPlace.PID = 1003; //purposefully commented for auto increment objContext.Places.AddObject(objPlace); objContext.SaveChanges();
I guess this is very basic question as I'm new to EF so please help me to sort it out.
You cannot assign value to the Identity column. its meaningless.
if you want to change the starting value of your identity column, why not do it through a simple script?
context.Database .ExecuteSqlCommand("ALTER TABLE Place ALTER COLUMN Id IDENTITY (1000,1)");
this will insert
Place.Id as 1000, for the first row in the table, and then 1001,1002... and so on for subsequent rows.
Are you just wanting to do this in EF to learn the syntax? the reason I ask, is because you could set the seed on the column in SSMS (http://msdn.microsoft.com/en-gb/library/aa933196%28v=sql.80%29.aspx)
