Question

In my application I have a model Client with int primary key Id. (model generated from database by metalsql)

var c = new Client{Name = "jonny"};
myDbContext.Client.InsertOnSubmit(c);

This code causes an error when I add the second client, because it turns out it Id field isn’t being incremented. It just takes the default value of 0. Is there a smart way to make this autoincrement work?

Answer 1

In your current table your column ID is not set to int is identity so you need to supply it.

var c = new Client{ID = 2,Name = "jonny"};
myDbContext.Client.InsertOnSubmit(c);

To solve this make sure your table ID column is Set to int is identity to make your code works

var c = new Client{Name = "jonny"};
myDbContext.Client.InsertOnSubmit(c);
