Just released in SQL Server 2016 CTP 2.4 is a new feature that will allow us to compare execution plans. The main purpose of this feature is to provide a side-by-side comparison of two execution plans. This makes it easier to find similarities and changes on each plan. This is a very nice enhancement that aids in troubleshooting issues such as understanding the impact of rewriting queries or observing how a design change, such as an index, may impact the plan. In the tip below, we\u2019ll go over how it works.<\/p>\n

For this post, I\u2019m using the AdventureWorks2014 database and I\u2019m going to use the following query:<\/p>\n

SELECT FirstName, LastName, CreditCardID \r\nFROM Person.Person p \r\nINNER JOIN Sales.PersonCreditCard c ON p.BusinessEntityID = c.BusinessEntityID\r\nWHERE p.ModifiedDate > '2014-01-01'<\/pre>\n
pen SQL Server Management Studio (SSMS) 2016 and execute the query with SET STATISTICS IO ON and \u201cInclude Actual Execution plan\u201c enabled.<\/p>\n
\"1-Compare<\/a>Click the Messages tab and you\u2019ll notice that we\u2019re doing 3819 logical reads on the Person table. This is a sign that this query can be tuned. We\u2019d like to get this number to the lowest possible.<\/p>\n
\"2-Compare<\/a><\/p>\n
Click the execution plan tab and you\u2019ll see the plan along with some Missing Index Details.<\/p>\n
\"3-Compare<\/a><\/p>\n
The execution plan is what we\u2019ll focus on in this tip, but I wanted to look at STATISTICS IO also to see if we can improve the number of logical reads.<\/p>\n
To be able to compare plan we\u2019ll need to save the execution plan. Right click anywhere in the plan window and select Save Execution Plan As\u2026 Choose a name and location and hit Save.<\/p>\n
