Sql server query tool 2005

Once that decision is made, it is usually a matter of doing some basic profiling of the application using Application Center Test and identifying where in the application performance is poor. Once the problem areas are identified, the next step should be to use SQL Server Profiler to inspect how the application uses database resources. When it comes to writing high-performance Web applications, there is a performance truism: if your application performs any cross-process communication database, Web services, remote object invocation it's a better use of your time to either optimize those communications or to remove them entirely before attempting to optimize other code within your application.

For database optimization, my general rule of thumb is if the application is going to the database more than once or twice on a given request or making a single Web service call , there must be a very good reason for it because those roundtrips are most often the cause of poorly performing applications.

My team at Telligent has just spent the past three weeks tuning our Community Server for forums. We made nearly 40 performance-related changes, of which 75 percent were in the database while the other 25 percent were directly related to code changes to either reduce or optimize the time spent in the database.

The caching features of ASP. NET are one of the best tools for reducing database round-trips. If you are using SQL Server you've already got a great set of tools, the Profiler and Query Analyzer, for understanding how your application is using the database. This book is one of my favorite references—my own copy is highlighted and coffee stained.

Hopefully your copy will enjoy a similarly useful existence. Reviewing logs or trace files generated by your application is invaluable for understanding how your app is being used. For example, for Web developers it is common to review IIS logs to understand app use. Within Community Server there is a built-in exception handler to trace all exceptions generated; later, we can review these logs and quickly get a good idea of the problem areas.

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.

Figure 1 shows a profiler session with the database used on the asp. You can see several captured SQL traces, which show stored procedures for weblogs. There is much passionate debate about using stored procedures. One of the benefits of stored procedures in enterprise applications is encapsulation and abstraction.

If an application is using dynamic SQL SQL text that is being generated on the fly , the application is typically more challenging to tune. Tuning dynamic SQL requires recompiling the application. Stored procedures, on the other hand, encapsulate their functionality and can be modified without affecting the public signature. Just as methods in your APIs are used for encapsulating functionality, stored procedures are in many ways the same capability, but in the database.

Of course there are also some good cases for using dynamic SQL. If dynamic SQL was used in any of the asp. However, there is none. I would also recommend installing SQL Server tools as part of any standard developer environment. Once you open Profiler you will need to first connect to a database before you can begin a profiling session. To connect to the database, select File New Trace. Note that you will need to be a member of the SQL Server sysadmin group to run profiler.

Next, after the credentials have been verified you will need to set some properties for the trace in the Trace Properties dialog.

By default, Profiler will capture events defined in the Standard template. This is an important subset of events rather than all of them. While the new tool is backward compatible and can be used to manage instances of SQL Server , in order to appreciate the full range of its capabilities, you need to operate it against a SQL Server installation. You can also use it to control SQL Server Mobile Edition providing that you have ActiveSync installed on the local system and the mobile device connected to it.

The interface of SQL Server Management Studio is modular and consists of the following main windows which can be, depending on personal preference, assigned floating, dockable, or tabbed characteristics, as well as be hidden or displayed using options in the View menu :. Unlike its predecessors though, it integrates with Data Transformation Services. This enhances its functionality, giving you the ability to design a workflow of a variety of maintenance tasks including standard T-SQL scripts and SQL Agent jobs , with flexible logic controlling transition between them.

Search Search. The interface of SQL Server Management Studio is modular and consists of the following main windows which can be, depending on personal preference, assigned floating, dockable, or tabbed characteristics, as well as be hidden or displayed using options in the View menu : Object Explorer - provides the ability to register, browse, and manage servers, as well as create, browse, and manage their components, including databases, their objects, and features such as security, Notification Services, replication, SQL Server Agent such as jobs, alerts, operators, and proxies , support services Distributed Transaction Coordinator and Full-Text Search , backups and maintenance plans, or SQL Server logs.

Objects are arranged in a hierarchical structure and can be ordered according to their type and schema or filtered using the Filter setting in the Object Explorer toolbar based on their name, schema, or date.

Their comprehensive information is available from the Summary View window, generated using Reporting Services and available from the View menu. There is also a new, asynchronous way of refreshing the main window, allowing you to access and manipulate already loaded objects without waiting for the process to be completed for others. The majority of administrative tasks can be easily scripted with the Script option available from the menu of the Properties window of an active node. With older versions of SQL Server, accomplishing the same goal required more creativity and time you could, for example, run the SQL Profiler trace to find out what T-SQL commands needed to be executed in order to perform a specific activity.

Once a task is scripted, it is also straightforward to schedule it for later execution using the Schedule option present in the same Properties window , which automatically creates an SQL Server Agent job note that schedules are identifiable by a name and might be assigned to multiple jobs.

Creating new objects, such as functions or stored procedures is made easier with assisted editors, which help you with formulating headers of T-SQL statements via a graphical interface, containing such settings as target object and database name, schema, Execute As context, parameters, or encryption settings. Registered Servers - allows you to register new servers and record connection information for each, with all associated settings such as authentication type and credentials, in case of SQL Server authentication , default database, network protocol characteristics, encryption, and time-out parameters.

Server registration can be exported from one instance of the SQL Server Management Studio and imported to another, simplifying management from multiple locations. Solution Explorer - implements the programming paradigm introduced in Visual Studio, which groups pieces of related code and associated information, such as connection settings into projects, which, in-turn, are grouped together to form a solution.

In addition, Solution Explorer has the ability to integrate with Visual SourceSafe for supporting version control tracking changes to the code and providing rollback capability. I am using sql server and i want to measure some query performance using an analyzer tool As always, SQL Server Management Studio also from the tools can be used to generate execution plans and determine query performance. I intended for this to be the link above, but I got my tabs confused :.

SQLProfiler for the express editions looks good can't vouch for it myself, though, as I use the profiling tools that come with the enterprise edition: see Codesleuth's answer for more info.
