❔ transaction.Rollback(); vs SaveChanges; at the end

using (var transaction = _db.Database.BeginTransaction())
        {
            try
            {
                // Remove all existing testimonials
                _db.Testimonials.RemoveRange(_db.Testimonials);

                // Add new testimonials
                _db.Testimonials.AddRange(newTestimonials);

                await _db.SaveChangesAsync();

                // If everything is successful, commit the transaction
                transaction.Commit();

                return Ok(new { message = "Success" });
            }
            catch (Exception)
            {
                // If an exception occurs, roll back the transaction
                transaction.Rollback();
                return StatusCode(500, new { message = "Error" });
            }
        }

using (var transaction = _db.Database.BeginTransaction())
        {
            try
            {
                // Remove all existing testimonials
                _db.Testimonials.RemoveRange(_db.Testimonials);

                // Add new testimonials
                _db.Testimonials.AddRange(newTestimonials);

                await _db.SaveChangesAsync();

                // If everything is successful, commit the transaction
                transaction.Commit();

                return Ok(new { message = "Success" });
            }
            catch (Exception)
            {
                // If an exception occurs, roll back the transaction
                transaction.Rollback();
                return StatusCode(500, new { message = "Error" });
            }
        }

Would the records be safe in case AddRange fails if I don't use RollBack?

ef would use transactions by default, as i understand it

if you only have a single .SaveChanges() call, then the entire transaction is really redundant unless you're using a non-default isolation level, for the transaction EF will execute all the underlying queries within a transaction, if not already inside a transaction context

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
