Getting started

SQL Enlight is a refactoring and static code analysis tool for SQL Server.
It offers a fast, automated way to ensure that your T-SQL source code fits your predefined design and style guidelines as well as best coding practices.

This topic contains the following sections:

Code and Database Analysis

SQL Enlight database analysis features are very similar to performing
static analysis to detect and correct defects in managed code. The advantage
is that SQL Enlight can make use of the dynamic management information provided
by SQL Server in order to provide more detailed and accurate analysis results and
to be used to monitor the health of a server instance, diagnose problems, and
tune performance.

Database developers and administrators can easily implement define and develop
custom rules by just using XPath and XSLT. The analysis rules can utilize the
following information to identify query performance pitfalls, index
fragmentation issues, missing or not used index cases, and missing column and
index statistics: dynamic management views and functions, existing indexes,
statistics, and query plans.


Code refactoring is the process of
changing a computer program’s source code without modifying its external
functional behavior in order to improve readability, maintainability,
extensibility, or reduce the complexity of the source code.

SQL Enlight has several features which can automate T-SQL code refactoring:
layout code to improve readability, extract parts of the large script in new
stored procedures or functions, and generate script summary or outline in order
to identify components and statements in large T-SQL scripts.


Besides the analysis and refactoring features, the tool provides several features which can improve
developers’ experience, facilitate and accelerate their work with SQL Server and
T-SQL code.

  • Validate the T-SQL code and highlight the syntax errors in the code editor.

  • Automated code reviews.

  • Instant access to recently executed T-SQL scripts.

  • Automatic fixes for code and database issues.
