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 detail 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 with 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 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 T-SQL script and highlight the syntax errors in the code editor.

Automated code reviews.

Instant access to recently executed T-SQL scripts.
