Learning SQL becomes simple when you follow a clear roadmap: understand databases, write basic queries, filter with WHERE, sort using ORDER BY, group data with GROUP BY, apply JOINs, use subqueries, and master aggregate functions. Structure builds confidence. #SQL #LearnSQL #DataAnalytics #Database

Giving AI agents visibility into SQL Server with MCP | Data Exposed MVP Edition
#AzureSQL #SQL #LearnSQL In this episode of Data Exposed, Anthony Nocentino and Anna Hoffman walk through two MCP (Model Context Protocol) servers that give GitHub Copilot real-time, controlled access to SQL Server. The agent never touches the database directly, it calls structured tools on the MCP server, which runs the queries that you control, and returns only what you've explicitly exposed. First, a custom-built server with 30 DMV-powered tools for DBA work across multiple instances. Then, Data API Builder (DAB) with zero code required for natural-language access to application data with permissions defined in config. Watch Copilot diagnose blocking, check AG health, and place a product order, all without writing a single line of SQL and all within guardrails you control. ✅ Chapters: 0:30 Intro to Anthony Nocentino 1:00 Why SQL MCP Server, for developers and DBAs 2:13 What is an MCP Server 2:58 Solution architecture 6:30 Control mechanisms 7:30 See the agent in action 8:45 SQL Server snapshot health example 14:20 Using Data API Builder as an application developer 19:00 Natural language interactions 20:30 Anthony's #1 piece of advice! ✅ Resources: https://github.com/nocentino/sql-mcp-server and blog https://www.nocentino.com/posts/2026-05-24-giving-copilot-visibility-into-sql-server-with-mcp/ About Anthony Nocentino: Anthony Nocentino is an accomplished technology professional, author, and speaker with over 30 years of experience in the IT industry.
