An execution plan is a behind-the-scenes look at the road a query takes in order to deliver it’s final result. As SQL developers, it is our job to understand how to read execution plans so we can see how the query is being executed. Now, the execution plan will be displayed for all queries within this session, until you turn it off. Hovering your mouse over each operation will display additional details about each operation.
These drill downs include valuable information including the index or object being referenced, the columns that are output by the operation, the predicates (or filters), estimated and actual statistics.
Many times, the execution plan will give you hints about what index could be added to speed up the query.
Microsoft has stated pretty clearly that they’re putting code on Azure first, ahead of the desktop. Let’s also note the little icons in the upper right of the plan, displayed to the left in full size. I promise you, with Tom, Dandy and I all talking at once, this will be informative and entertaining. Gabinet Weterynaryjny Medica-Wetzaprasza do skorzystania z uslug fryzjerskich dla Twojego pupila. I have started a research project to look to the current possibilities of SQL Azure Reporting Services. Of course these queries can't replace the powerfull features of SQL Profiler, but at least it will help you and it is better than nothing.
By enabling Client Statistics in SSMS you can see the number of Bytes received from the server, the total execution time, Wait time on server replies. Enjoy, using these DMV's till a good replacement is available for SQL Profiler on a SQL Azure database. My name is Andre van de Graaf, I'm working for Exact Software in the Research team as Principal Research Engineering.


Now I have never spoken to anyone on the SQL Server Development team, however I would imagine that there are some extremely sharp people in the query optimization team. They are generated from the underlying data statistics combined with what the query and it’s parameters are trying to accomplish.
The first paths the query takes are on the right hand side and extend all the way to the left until it gets to the final node.
Sometimes this will lead you to find a missing index, modify an existing index, or even break the query up into multiple parts.
This can be due to a number of reasons, but personally, I try to take those reasons away from the optimizer by breaking my complicated queries up into multiple queries and using temp tables. Which makes one wonder when we’re going to start to see some of this cool stuff within SSMS. The only beef I have with it is that it doesn’t really sort the operators so much as change the display. Clicking on these completely changes what’s represented to us from the execution plan. What we have are the operator nodes, listed by Node ID order, showing some of the interesting information from the properties in a grid format. And the little blue icons next to the operator names do allow you to expand and collapse the layout. It’s called How to be a Successful DBA in the Changing World of Cloud and On-Premise Data.
In my opinion, applications should be very simple to use and do not have dozens of options.
You can hide this tool bar by clicking anywhere within it that’s not on one of the icons.
As you can see, you only get a few operator types, Warnings, Scan, Seek, Merge Join, Hash Match, Nested Loops and Sort.
And yeah, because it’s a grid, I can click on any of the column headers and get different sort order for the data.


We’ll spend all day getting you deep into the guts of Azure SQL Database showing how to administer it, tune it, grow it, and make it work. Every application should perform very fast, even in high transactions volume or high multi user environments. To use SQL Azure Reporting Services you need to create a SQL Azure database and upload content to it. In this blogpost I will share some usefull queries on these DMV's which you can use to analyze the performance of your application on a SQL Azure database. With a good amount of practice, you can begin to correlate how the query is written with the way the execution plan is laid out. I write articles for publication at SQL Server Central, Simple-Talk, PASS Book Reviews and SQL Server Standard.
For large plans, this can be a quick and easy way to find the highest estimated cost, or the largest number of actual rows. I have published two books, ”Understanding SQL Server Execution Plans” and “SQL Server 2008 Query Performance Tuning Distilled.” I’m one of the founding officers of the Southern New England SQL Server Users Group and its current president. With these statistics in hand, the goal is to eliminate the largest number of records as quickly as possible, and iterate through this process until the final result is delivered.
The grid is just the same XML data that makes up the execution plan laid out slightly differently. But, I can modify the display of the plan so that I only see estimated CPU cost or estimated IO cost.
