Static Analysis Rule-sets for SQL Projects

Overview

A library of SQL best practices implemented as over 140 database code analysis rules checked at build time.

The rules can be added as NuGet packages to SQL Database projects:

For a complete list of the current rules we have implemented see here.

Usage

The latest version is available on NuGet

dotnet add package ErikEJ.DacFX.SqlServer.Rules
Modern SDK-style Projects

The rules are available as a NuGet package that can be added to your SQL Database project. The rules will run during build, and report any issues in the Error List window.

You can read more about using and customizing the rules in the docs here

Classic .sqlproj Projects

You can download and manually use the rules with Visual Studio and "classic" SQL Database projects, as described in my blog post here.

Command line tool - T-SQL Analyzer CLI

This repository also contains a .NET command line tool that uses the rule set.

You can use it to analyze SQL scripts or SQL Database projects and output the results in a variety of formats, including XML and JSON.

You can also use the tool as an MCP Server with GitHub Copilot in VS Code and Visual Studio, allowing you to get feedback on your SQL code using GitHub Copilot Chat.

The T-SQL Analyzer MCP Server supports quick installation across multiple development environments. Choose your preferred client below for streamlined setup:
