Force output does not work for merge. about entityframework-extensions HOT 3 OPEN

Hello @Alexn ,

I should have said it in my first answer: you also need to select which properties you want to output.

Here is a working fork from your latest Fiddle: https://dotnetfiddle.net/XvCPIs

context.Set<Customer>().BulkInsert(customers, options => 
{
	//options.ForceSelectOutput = true;
	options.InsertIfNotExists = true;
	options.InsertKeepIdentity = true;
	options.ColumnOutputExpression = x => new { x.Name, x.Email, x.Note, x.Created, x.Updated   };
	options.ForceOutputFromUnmodifiedRow = true;
});

I commented the option options.ForceSelectOutput = true; as it might not do what you think (This option, instead of directly outputting values, it output in a temporary table then select it, which is required in some scenario such as when we cannot automatically discover the table have a trigger)

Hello @Alexn ,

Thank for reporting.

Unfortunately, we don't have any solution at this moment to cover this scenario.

We have the option options.ForceOutputFromUnmodifiedRow = true;, but it currently only works in this 2 scenarios:

• BulkInsert + InsertIfNotExists
• BulkMerge without an UPDATE statement

We currently have a new method under development that will allow you to read and output values directly into your entities, but it will still take several weeks before we complete it.

Hello @JonathanMagnan,

Thanks for answer. I tried to use BulkInsert + InsertIfNotExists, and it does not work as expected.

Could you please look in to the Fiddle, and figure out it?
