Version 1.7.3.515 of SQL Enlight is already released and available for download.

Here is what’s new in this release:

• Extended query execution plan analysis support
• A new analysis rule for query execution plan analysis – EX0018
• A new external template parameter support in the command line tool and MSBuild tasks
• Small improvements and fixes

The new parameter is added to provide a way to set external analysis template which to be used during analysis instead of the default one. Check the SQL Enlight documentation for the command line tool and MSBuild tasks parameters.

As the Execution Plan Analysis is the most important feature update in this release, here we have prepared a separate post for it.

We will be happy to help you if you have any questions or comments.

Thank you!

Last week we released a new version of SQL Enlight – 1.7.2.513.
It contains just small fixes and 2 new features:

• A new layout rule ‘Miscellaneous->Keywords padding’.

-- Keyword Padding option set to 10:
SELECT     ProductID ,
           SpecialOfferID ,
           AVG( UnitPrice ) AS 'Average Price' ,
           SUM( LineTotal ) AS SubTotal
FROM       Sales.SalesOrderDetail
WHERE      SpecialOfferID IN(  1 ,
                               2 ,
                               6 ,
                               9 )
GROUP BY   ProductID ,
           SpecialOfferID
ORDER BY   ProductID ,
           SpecialOfferID DESC

-- Keyword Padding option set to 0:

SELECT ProductID ,
       SpecialOfferID ,
       AVG( UnitPrice ) AS 'Average Price' ,
       SUM( LineTotal ) AS SubTotal
FROM Sales.SalesOrderDetail
WHERE  SpecialOfferID IN(  1 ,
                           2 ,
                           6 ,
                           9 )
GROUP BY ProductID ,
         SpecialOfferID
ORDER BY ProductID ,
         SpecialOfferID DESC

• A new XSLT extension method ‘execute-query-plan’ which to enable support for query plan analysis.

We will describe in more detail the usage of this method in the next post.

The new version is already available for download here.

One of the most exciting features in SQL Enlight is the ability to create your own static analysis rules. This is very powerful feature which can be of great use and unleash almost unlimited number of possibilities for the ones who consider trying it.
