Common properties

Introduction

To really understand what each operator’s role within an execution plan is, it is not enough to just look at the graphical plan to check all operators. You need to dig a level deeper, to the properties of each operator.

Property list

This table below lists the properties that you can find on all, or at least most operators; and that have a common meaning wherever you find them. There are also many properties that are specific to a single operator or a small group of operators; and a few properties that have the same name but a different meaning depending on the operator. Those will not be described here, but on the operator’s own page.

Implicit properties

Apart from the properties that are exposed in the execution plans, operators also have properties that are important to know, but not exposed in the execution plans. These are not exposed because they are part of how the operator always works, so apparently Microsoft felt no need to expose them, trusting that people who look at execution plans will know this. Below is a description of each of these properties. On the individual pages for all operators covered at this site, you will find the values for these implicit properties for the operator.

Note that the names of these properties are commonly used, but not official. You will not find them in any execution plan, but you may find them on many other internet sites.
