SQL Server Profiler can be used to view live sessions of activity on your running SQL Server database. You can glean important information such as how many queries your database is executing, how much time those queries are taking, which database is executing which query, and so on.
To run the query in Query Analyzer, first paste the contents into Query Analyzer, then go to the toolbar and select Query Show Execution Plan. Next, highlight the SQL to execute and press F5. Figure 3 shows my results.
Immediately below the SQL query that was executed is the results grid, which shows what is returned by the query. In this case there are two resultsets returned. The first resultset is a list of Sections (forums) and the second one is a set of permissions. Community Server uses a role-based permissions system to control what users can or cannot do within the system. Whenever a list of Sections is retrieved, the system also refreshes its list of permissions for those sections.
In addition to running queries, Query Analyzer allows you to analyze a query. Recall that you enabled the showing of the execution plan before executing the SQL. The plan provides a visual diagram of how SQL Server is executing your query, what indexes it uses, and other data that can help you optimize indexes or other data needed by SQL Server to enhance query performance.
Figure 4 shows each query executed, its execution plan, indexes used, joins, and the amount of data returned from each operation. Even the arrows between each item have significance: the thickness of the arrow is a visual indication of how much data is returned by that operation; that is, a poorly tuned query might have many thick arrows indicating operations which are likely returning too much data.
I've actually only just found out about the issue as my daily routine involves just running copy queries on the DB and these work fine with both ADP and Query Analyzer. It's only because I thought I might need to edit a query and checked it (luckily I didn't) that I encountered the issue.
You mentioned that you are managing the database. Of course you can do everything you need using T-SQL from a query window, but going with any other tool (like MS Access, Query Analyzer 2000, FlySpeed SQL, Oracle SQL Developer, etc.) you're going to miss out on database management related functionality in the GUI.
There is a free and portable (no install) tool called FlySpeed that I've used on occasion, which is ok for querying and navigating databases / objects. I keep it on my thumbdrive for those occasions where I need database access and SQL Server client tools aren't installed. In addition to SQL Server, it also supports several different RDMS, including Oracle and MySQL. It comes in handy, if you're a consultant wearing a lot of hats.
The editors in SSMS share a typical architecture. The text editor implements the base level of functionality and can be used as a basic editor for text files. The other editors, or query editors, extend this functionality base by including a language service that defines the syntax of one of the languages supported in SQL Server. The query editors also implement varying levels of support for editor features such as IntelliSense and debugging. The query editors include the Database Engine Query Editor for use in building scripts containing T-SQL and XQuery statements, the MDX editor for the MDX language, the DMX editor for the DMX language, and the XML/A editor for the XML for Analysis language.You can use the Query Editor to create and run scripts containing Transact-SQL statements.
Requests a query execution plan from the query processor without executing the query, and displays the plan in the Execution plan window. This plan uses index statistics to estimate the number of rows expected to return during each part of the query execution. The actual query plan that is used can be different from the estimated execution plan. If the number of returned rows is different from the estimate, and the query processor changes the plan to be more efficient, this can occur.
When the query executes, the Save Results dialog box opens. In Save In, select the folder in which you want to save the file. In Filename, type the name of the file, and then select Save to save the query results as a Report file that has the .rpt extension. For advanced options, select the down-arrow on the Save button, and then select Save with Encoding.
You can access the context menu by right-clicking anywhere in the query editor. The options in the context menu are similar to the SQL Editor Toolbar. With the context menu, you see the same options as Connect and Execute, but you also get other options listed, such as Insert Snippet and Surround With.

The Microsoft Database Engine Tuning Advisor (DTA) analyzes databases and makes recommendations that you use to optimize query performance. You use the Database Engine Tuning Advisor to select and create an optimal set of indexes, indexed views, or table partitions without having an expert understanding of the database structure or the internals of SQL Server. Using the DTA, you can perform the following tasks.
Results to File - When the query executes, the Save Results dialog box opens. In Save In, select the folder in which you want to save the file. In File name, type the file's name, and then select Save to save the query results as a Report file with the .rpt extension. For advanced options, select the down-arrow on the Save button, and then select Save with Encoding.
You use the Properties window to view the properties of the current connection. Many properties are read-only in the Properties window but can be changed elsewhere in the Management Studio. For example, the Database property of a query is read-only in the Properties window but can be changed on the tool bar.
Selecting data from a database You retrieve data from a database by creating a query, which is a question that you ask about data stored in an external database. For example, if your data is stored in an Access database, you might want to know the sales figures for a specific product by region. You can retrieve a part of the data by selecting only the data for the product and region that you want to analyze.
Use the Query Wizard for most queries The Query Wizard makes it easy to select and bring together data from different tables and fields in your database. Using the Query Wizard, you can select the tables and fields that you want to include. An inner join (a query operation that specifies that rows from two tables are combined based on identical field values) is created automatically when the wizard recognizes a primary key field in one table and a field with the same name in a second table.
You can also use the wizard to sort the result set and to do simple filtering. In the final step of the wizard, you can choose to return the data to Excel, or further refine the query in Microsoft Query. After you create the query, you can run it in either Excel or in Microsoft Query.
Work directly in Microsoft Query for other types of queries If you want to create a more complex query than the Query Wizard allows, you can work directly in Microsoft Query. You can use Microsoft Query to view and to change queries that you start creating in the Query Wizard, or you can create new queries without using the wizard. Work directly in Microsoft Query when you want to create queries that do the following:
Reusing and sharing queries In both the Query Wizard and Microsoft Query, you can save your queries as a .dqy file that you can modify, reuse, and share. Excel can open .dqy files directly, which allows you or other users to create additional external data ranges from the same query.
After you create a query in either the Query Wizard or Microsoft Query, you can return the data to an Excel worksheet. The data then becomes an external data range or a PivotTable report that you can format and refresh.
One of the main challenges that database administrators face is to identify time consuming queries and determine how best to tune them. To accomplish this, database administrators often rely on having a trend analysis of workloads and queries, including query durations.

You should see all your databases and containers on the top. You can easily find how many physical partitions a container has by clicking the Partition List button. You will see a list in a popup window. In the following example, the selected container has 5 physical partitions. If you do not include the partition key of your container in your queries, Azure Cosmos DB will run your query in 5 physical partitions.
You can see execution Metrics by clicking on the tab to the right side of the results. There are two numbers here you should watch closely. Retrieved Documents value and Index Hit Documents value should be equal or very close to each other. The gap between these two numbers tells you that there might be some opportunities to make your query faster/cheaper. Usually, you fix this problem by changing your indexing policies.
