实体框架不保存新列

Question

I added a new column to an object, and used EF to update the model from the database.

Normally we do the following:

context.BulkInsert(records, GetBulkInsertOptions());
context.SaveChanges();

But this doesnt seem to work for the new column. If I do the following it works, but is obviously not ideal.

foreach (var r in records)
{
    context.MyDBObject.Add(r);
    context.Entry(r).State = EntityState.Modified;
    context.SaveChanges();
}

Can anybody shed some light on this? Additionally, if I erase the row in the database before it does a save, it will insert everything, except for the new column I added.

edit: Using Entity Framework v6.2.0 and EntityFramework.BulkInsert v6.0.3.8

edit 2: If I erase the row, and try to insert a new object using only the following

context.MyTable.Add(test);
context.SaveChanges()

This also inserts the object, but doesnt include my new column. This leads me to believe its more an error with EF and less with the BulkInsert as I alluded to previously.

Answer 1

The issue was caused by Triggers in the table in Mssql.

Doing context.Database.Log = Console.WriteLine; Helped us determine that Entity Framework was sending the right query to SQL. Testing the query in SQL showed that the new column wasn't being saved.
