SSMS Query Assistant-SSMS Optimization Tool

Example

SELECT * FROM Orders INNER JOIN Customers ON Orders.CustomerID = Customers.CustomerID WHERE Customers.City = 'London'

Scenario

In this scenario, the assistant might suggest adding an index on 'City' in the 'Customers' table or rewriting the query to reduce the data load by filtering out unnecessary columns, potentially improving query performance dramatically.

Example

User needs to extract year-to-date sales but is unsure how to write a SQL query that groups sales by month and calculates totals.

Scenario

The assistant provides a T-SQL script that demonstrates how to use the GROUP BY clause with the SUM function, helping the user efficiently create the needed report.

Example

A query that usually runs efficiently starts taking significantly longer.

Scenario

The assistant could guide the user through using SSMS's built-in performance reports and activity monitor to identify bottlenecks, like long-running queries or blocking processes, and suggest corrective actions such as query hints or transaction isolation level adjustments.
