Why Auto Create Statistics is an Important Setting in SQL Server

Auto create statistics is a crucial setting in SQL Server that significantly impacts the performance of your queries. When enabled, it allows SQL Server to automatically create statistics on columns used in predicates. Here’s why it’s important:

Improved Query Performance: Statistics provide vital information about the distribution of data within your tables, helping the Query Optimizer to make better decisions.
Automatic Maintenance: Auto create ensures that statistics are generated and updated as needed without manual intervention.
Adaptability: Helps SQL Server adapt to changes in your data patterns over time, ensuring statistics reflect current data.
Reduced Likelihood of Suboptimal Plans: Reduces the risk of the Query Optimizer making poor choices due to outdated or missing statistics.
Simplicity and Focus: Allows database administrators and developers to focus on other aspects, trusting SQL Server to handle this part of query optimization.

While auto create statistics is generally beneficial, it’s just one part of ensuring your SQL Server performs optimally. Tools like Database Health Monitor provide deeper insights into your server’s health and performance. For more in-depth learning, consider enrolling in Stedman’s SQL School classes.
