ORMLite error on insert with autoincrement key

magicleon Published in 2018-01-12 15:45:29Z

I have the following MVC 5 Model:

public class Map {
    public int Id { get; set; }

    public String Name { get; set; }



The id attribute on the table is a primary key autoincrement.

I need the Id to perform update operations but this prevents me to insert new entries.

This update works:

var res = dbConnection.Update<Map>(map);

While this insert does not:

var res = dbConnection.Insert<Map>(map, selectIdentity: true);

I get this exception:

Cannot insert explicit valuefor identity column in table 'map' when IDENTITY_INSERT is set to OFF.

What can I do to solve this?

The [AutoIncrement] attribute instructs ORMLite to omit the attributed field from the INSERT field list.

So apply it to the Id property:

public int Id { get; set; }

And its value will be ignored when inserting or updating that entity.
