Output of generated keys not working for UUID / uniqueidentifier

I am using UUID / uniqueidentifier primary keys.

CREATE TABLE test (
  id UNIQUEIDENTIFIER DEFAULT NEWID(),
  text VARCHAR(255)
)

When inserting a new object, I dont get the generated id. GENERATED_KEYS is empty.

INSERT INTO test (text) VALUES('test') select SCOPE_IDENTITY() AS GENERATED_KEYS;

Will return NULL.

That is an issue of SQL Server but the workaround would be to use the OUTPUT syntax:

INSERT INTO test (text) OUTPUT inserted.id VALUES('test');

That will actually return something like | id | B5BA707B-872E-4BFC-8A96-97A1D789E74C |

Whatever works with custom statements, r2dbc-mssql doesn’t return ids with spring-data-r2dbc where other drivers do.

We switched to r2dbc-postgresql for that reason and everything works fine.

Thanks, I missed that subtlety.
