Introduction

The Ghost in the Machine: Why “VS Cursor 12.0 Extended” Redefines the War for Your Workflow

Legacy Cursor:

Scenario: Iterating over a live IoT_sensor_data table while inserts occur simultaneously. 5,000 rows/sec – frequent deadlocks. VS Cursor 12.0 Extended: 42,000 rows/sec – zero deadlocks due to time-travel reads.

When Not to Use VS Cursor 12.0 Extended

  1. Small datasets (< 10,000 rows): The overhead of setting up parallel threads exceeds the benefit. Use a simple WHILE loop or set-based operation.
  2. Highly volatile tables with READ UNCOMMITTED: Time-travel reads add a microsecond of version checking. Not worth it for dirty reads.
  3. Linked server queries: The extended cursor does not push down parallel threads to remote servers.

The "extended" part might imply that this cursor feature has additional functionality or capabilities beyond the standard cursor features. Introduction
