Streamline SQL Workflow with Snowflake Copilot
Can you imagine having a tool that effortlessly bridges the gap between you and your data, allowing you to focus on insights rather than the complexities of coding. Released in April 2024, Snowflake Copilot is precisely that – an assistant designed to make working with data in Snowflake simpler and more intuitive.
With Snowflake Copilot, you can ask questions in plain English, like “What were the total sales last month?” and instantly receive the correct SQL query. This tool seamlessly integrates with Snowflake’s SQL Worksheets and Notebooks, ensuring that your data access permissions are always respected, so you only interact with the data you’re authorized to see.
Let’s dive into the features, limitations, and best practices of Snowflake Copilot to help you harness the full potential of this innovative tool.
What is Snowflake Copilot?
Snowflake Copilot is a sophisticated LLM-powered assistant designed to streamline your data analysis process within Snowflake. Its main function is to make data exploration and insight extraction easier by translating natural language into SQL queries. Unlike typical AI tools, Snowflake Copilot is built on Snowflake Cortex, an intelligent, fully managed AI service that operates securely within the Snowflake environment. This advanced tool understands the nuances of data analysis and SQL queries, making it a valuable resource for navigating your data.
Security First
One of Snowflake Copilot’s standout features is its robust security. Your data remains securely stored within Snowflake, and Copilot adheres strictly to your RBAC settings, ensuring it only accesses data you’re permitted to see. Currently, Snowflake Copilot is available in specific AWS regions:
If your Snowflake account is in one of these regions, you’re all set to start using Copilot. If not, don’t worry – Snowflake plans to expand its availability soon.

Now that we’ve covered what Snowflake Copilot is, it’s time to dive into what it can actually do. Let’s break it down and explore each of its key features.
1. Data Exploration Discovering what’s inside a new dataset can be daunting. Snowflake Copilot simplifies this by allowing you to ask open-ended questions about your data.?
For example, you can inquire about the types of information in your dataset or how the main tables are related. Copilot analyzes the schema and provides a concise summary to help you get started.
2. SQL Query Generation Writing complex SQL queries can be challenging. Snowflake Copilot shines in this area by generating SQL queries based on plain English descriptions.?
For instance, you can request a query to retrieve details of students older than 20, and Copilot will generate the corresponding SQL query for you. It can handle complex requests involving window functions, subqueries, and joins with ease.
3. SQL Query Execution Once Snowflake Copilot generates a query, you have the option to execute it immediately or add it to your Snowflake Worksheet. This flexibility allows you to run the query right away or modify it as needed for further analysis.
4. Complex Query Building and Refinement Iterative query building is where Snowflake Copilot truly excels. You can refine your queries step-by-step, improving and adjusting them based on the results. This conversational approach to query development is ideal for complex analyses that require multiple iterations.
5. Snowflake Learning Resource Snowflake Copilot also serves as an educational tool. If you’re new to Snowflake or need clarification on specific features or best practices, you can ask Copilot for explanations. It provides clear and concise answers, making it a valuable resource for learning.
6. Query Performance Optimization Creating efficient queries is crucial for performance. Snowflake Copilot can analyze the efficiency of your queries and suggest optimizations, such as rewriting joins or adding indexes, to enhance performance.
7. Custom Instructions You can customize Snowflake Copilot’s behavior by setting specific instructions. For example, you can instruct Copilot to always add comments to generated queries or use common table expressions (CTEs) instead of subqueries. These customizations help tailor Copilot to your preferences and standards.
8. Feedback Integration You can provide feedback on responses and suggest enhancements, helping the development team make Copilot even better.
