![]() For example, after opening a new query window in SSMS, select Query, Include Actual Execution Plan and run the following query against the AdventureWorks sample database: SELECT ST.Name AS TerritoryName, With SQL Server 2005, you use SSMS to do so. The easiest way to look at an execution plan is to view its graphical representation. SQL Server 2005 can return a query execution plan in three formats: text, XML, and graphical. The second step involves executing the plan. The first step is to compile the query into a plan. When you run a query against the relational database engine, SQL Server carries out two major steps. I’ll first show you how to use execution plans within SQL Server Management Studio (SSMS), then show you how execution plans can be used from a client application. ![]() Let’s take a look at how execution plans can be used to estimate both the complexity of queries and the size of query result sets. With this requirement in mind, I began investigating whether SQL Server execution plans could provide a solution. My customer wanted to prevent these types of reports from being executed. After rolling out an ad hoc reporting tool, some of the business users began building reports that were very complex and, in some cases, resulted in tens of thousands of rows being returned. We can use the browse button at the top right of the chart and we can use the Run Query or Refresh to see the query used and refresh the report.A few months ago, one of my customers began experiencing performance problems with their new reporting environment. The wait starts if the thread is idle and ends when the thread has something to do. The SOS_WORK_DISPATCHER occurs when an SQLOS thread is waiting for something to do. Wait counts are related to waits of workers. If we click the Performance tab, we will see the Wait Counts. When you create backups, the memory usage increases, with this report, you can verify the size used by the backups created during time and plan if you will need more space in the long run. A high % of CPU usage means that you may need to update statistics, maybe add indexes, or enhance the design of the low-performance queries. It is not visible in SSMS and it contains system objects. This is a read-only internal system database. If the percentage is high very often, you should consider adding more memory. The buffer usage percent is a percentage related to the memory to store data pages. If there is not enough physical memory, you do not have the data in the cache and then the data is retrieved from disk which decreases the performance. The report shows the top 10 databases that take more space. Not only does it show the data file space used, but also, the log space used per database. Secondly, in ADS, go to Connections and select your SQL Server connection to right-click the connection and select Manage. This is a cool extension to monitor the Database space usage, CPU utilization, MB used per backups, buffer usage, and more.įirstly, to install in ADS, go to extensions and search the Server Reports and install it. The other extension that we want to show in this article is the Servers Reports. Optionally, at the right of the pane, you also have the Clear All history option to clear all the query history and Pause to pause momentarily the query history. Finally, we have the Pause Query History Capture to pause the query history capture.Also, we have the Clear All History option to clear all the records from the job history.Thirdly, we have the Delete option to delete the query from the query history.Secondly, Run Query runs the query again.Firstly, open Query opens the query to edit it.If you right-click on the query, you have the following options on the context menu: ![]() In addition, you will be able to see the database where it was executed as well as the date and execution time. You will be able to see the queries successfully executed in green and in red with an X of the queries that failed. In the lower pane, go to the Query history tab to check the queries executed. Once installed in Azure Data Studio, go to the Menu and select View>Output (I tried View>Query History and it did not work, however, it could work on your side). Enjoy them! Requirementsįirstly, in order to install the extension, in the ADS go to Extensions and search for the Query History extension and install it. ![]() We will show the features of both extensions here at SQL Server Central. Secondly, the Server Reports extension allows having reports about the DB Space, Buffer usage, CPU utilization, Backup Growth Trend, and the Wait counts. Firstly, the Query History extension allows having the history of the queries executed. In this article, we will cover these extensions. Query history and server reports are two popular extensions in Azure Data Studio.
