How do I disable generating outlines when running the SQL Optimizer?
During the optimization process, no Outlines are generated. All the alternatives returned are purely rewrites and execution plans. The green pins you see are just an indication on the compatibility in creating and deploying an Outlines based on that alternative. The green pins are only estimated based on the rewrite process. Again, no Outlines were received so far. It is only when user chooses to deploy an Outline will then Tuning try to get Outline from database.
