SSMS 21 Copilot: Here’s How It Works

SQL Server Management Studio (SSMS) has been a staple for database professionals for years. With version 21, Microsoft has added something many users have been waiting for: native Copilot integration. No extensions, no hacks—just open it up, connect to Azure, and start working smarter. Here’s a walkthrough of the most important features SSMS 21 Copilot offers and how they work in practice.

You write the query, run it, catch a missing condition, tweak the join, test again—repeat until it’s right. SSMS 21 brings Copilot into that loop.

TL;DR:

• SSMS 21 now includes built-in Copilot—no extensions. Just require connection to your Azure OpenAI deployment (like GPT-4o).
• Works only with SQL Server connections (not SSIS, SSAS, or SSRS).
• Runs in read-only mode—won’t execute any DML or modify data.
• Can generate queries, fix broken SQL, and suggest optimizations.
• Supports prompts like: “fix this query,” “optimize for performance,” or “generate insert script.”
• Ideal for SQL developers who want help writing, debugging, or learning better query patterns—without giving up control.

Installation: Copilot Comes Built-in

The installer for SSMS 21 clearly shows that Copilot is not an afterthought—it’s front and center. Once you launch the installer, you’ll notice the “Copilot Integration” checkbox enabled by default. This means no manual setup is required post-install. It’s part of the core experience now.

First Run: Setting Up Your Azure OpenAI Keys

Once SSMS launches, you’ll be prompted to connect Copilot to your Azure OpenAI setup.

In the first prompt, you’ll be asked to provide:

• Azure OpenAI service endpoint
• Azure OpenAI deployment
• Azure OpenAI API key

If you haven’t already created this in Azure, it’s a quick process: deploy a model, generate a key, and you’re good to go. we see how this information is pasted into SSMS.

It’s a one-time step, and once entered, Copilot starts responding instantly within SSMS.

To get an Azure OpenAI deployment name for SSMS Copilit, we need Gen AI model. That’s the engine powering your Copilot. GPT-4o is optimized for speed and real-time interaction, making it well-suited for something as dynamic as SQL writing and analysis.

If you already use GPT-based models in Azure, you can reuse the same deployment. If not, create a new one and pick GPT-4o or other depending on availability.

Which Connections Are Supported?

As of now, Copilot in SSMS works only with SQL Server connections—whether it’s a local database or Azure SQL.

It does not support:

• SQL Server Integration Services (SSIS)
• SQL Server Analysis Services (SSAS)
• SQL Server Reporting Services (SSRS)

So if you’re connected to an SSIS or SSAS instance, you won’t see Copilot suggestions. It’s focused purely on Transact-SQL (T-SQL) scenarios for now.

Read-Only Mode – No Live Data Changes

Copilot works in a read-only mode inside SSMS for GOOD.

It will not execute updates, deletes, or any data-modifying queries on its own. It doesn’t have permissions to alter databases or run DML commands. You remain in full control.

That said, it can generate update, insert, and delete queries for you, which you can review, tweak, and run manually. This helps reduce the risk of accidental changes while still speeding up development.

Quick Demo: Fixing a Broken Query

I pasted a malformed SELECT query into SSMS. Copilot immediately offered a fix and even explained what was wrong.

Few Prompt Examples: Result Accuracy

In below example, we asked Copilot to generate a complex query involving filters, aggregates, and joins. The result was accurate and ready to run with minimal edits.

the same query was further optimized by Copilot after being prompted with: “Make it efficient.” It introduced indexing suggestions and added a WITH (NOLOCK) hint—something even experienced developers can forget.

In another example, we asked Copilot another question on a different query context (another database connection), and it just worked fine.

These examples show that Copilot isn’t just copying boilerplate SQL—it understands context and best practices.

Should You Use This?

If your daily work involves writing or reading SQL, then yes—this is probably the most useful update to SSMS in years.

Here’s what it helps with:

• Writing long queries faster
• Understanding joins and filters
• Fixing syntax issues
• Learning better SQL patterns
• Generating stored procedure templates
• Drafting DML scripts (but not running them automatically)

What It Won’t Do (Yet)

Let’s be clear:

• It won’t connect to SSIS/SSAS/SSRS
• It won’t execute anything that modifies data
• It won’t automatically run DDL/ DML code it suggests

This is intentional, for safety and audit reasons. Think of it as a smart assistant—not a trigger-happy automation engine.

A Note on Privacy and Control

Copilot integrates directly with your Azure environment, so you control what it accesses and shares. It processes your prompts and data securely within your subscription. According to Microsoft, it doesn’t store any query logs outside your environment, which helps meet compliance requirements for enterprise users.

SSMS 21 doesn’t just add Copilot—it integrates it naturally into the flow of writing, editing, and reviewing SQL. It’s fast, context-aware, and doesn’t get in the way.
