you can see for yourself.Just click Show all events to make the selection of all events.We can also filter the statistics fields, click any of the column headings to view a description of the column asWe indicate from the above:TextDate relies on the text value of the event class captured in the trace;ApplicationName the name of the client application that created the SQL Server connection. This column is populated by the value passed by the application, not by the program name that is displaye

DemandUse SQL Server Profiler to track all common activities of the current instance and save the results to a file.================================================================In the Start program, select SQL Server Profiler.650) this.width=650; "title=" "style=" border-top:0px;border-right:0px;background-image:none;border-bottom:0px; padding-top:0px;padding-left:0px;border-left:0px;padding-right:0px, "

The ability to query a table is the main reason why you should have the SQL Profiler trace output to the table. It is much easier to filter the data in this table than to create a SQL Profiler. If you don't have the time to fully build the SQL Profiler, this is usually the right thing to do. A day passes before another heap of data is captured, without answering

Label:SQL Server Profiler is a SQL Server Enterprise Edition with a very powerful statement tracking and analysis tool. Using it skillfully is useful for us to analyze database performance issues, such as when data Access uses an ORM framework such as EF, we often need to look at the SQL statements that it generates to us, and then analyze performance issues, and I intend to summarize them in the following ways. Environment configuration

In two or more SQL Server processes, each process locks a resource that another process is trying to lock, and a deadlock occurs, for example,The process Process1 holds 1 exclusive locks (x) on Table1, while PROCESS1 requests 1 exclusive locks (x) for Table2,Process Process2 holds 1 exclusive locks (x) on table2, while process2 to Table1 requests 1 exclusive locks (x)In this case, a deadlock occurs, except when an external process disconnects a deadlock, the two transactions in the deadlock will

of ORM tracing is that the orm framework generates dynamic SQL statements and can run them directly, but it is very troublesome to modify them.See the following dynamic SQL statement example. Execute (n' select * from groups ')Sp_executesql n 'select * From groups'When it comes to dynamic SQL statements, this sentence may be very important: Execute brackets can only contain string variables, string constants, or their concatenation, and cannot call other functions or stored procedures. If you

]. [Suincluded]From[Framework]. [DBO]. [User]Where([Framework]. [DBO]. [User]. [Userid] ='Mis'/* @ P1 */)) As you can see, this tool has directly filled the parameters in the SQL statement and can be directly executed in the query analyzer without any modification. Orm profile calls every trace session snapshot. In the SQL document, this word is translated as a snapshot and can be understood as a trace session. It can be saved on the hard disk for further analysis. For the win froms progr

SQL Server has an SQL profiler that can track the SQL statements executed by the server in real time, which is useful in many times for debugging errors. For example, the complexity of othersCode, Production system, no debugging environment, no original code ...... After checking the information, My SQL can use the following method to track SQL statements. The following method is similar to that of Linux on the Windows platform: 1. Configure the m

prompt.Note that the following port number is not the 54999 that was opened by ADB before, if not, it is invalid.6, next do not close the profile panel, click File–buildrun, wait for download, and then your project will be running on the phone.7, so as long as ensure that the profile panel is not closed and mobile phone constantly open, change the project after the execution of File–buildrun can be re-tested in the real machine.Note: Do not connect to the phone to check if USB is connected, che

SQL Server Profiler can detect statements executed on the data, especially if some projects do not directly use SQL statements, directly using the ORM framework of the system to process the database project, when debugging SQL statements, it is very helpful.Previously wrote the article "SQL Server Profiler Tracking database deadlock" Using SQL Server Profiler to

SQL Server Profiler (Profiler) helps database administrators track specific events that are performed by SQL Server databases, monitors the behavior of the database, and saves these valuable information to a file or table for later analysis to resolve problems with the database. Optimizes the performance of the database engine. This step-by-step article describes how to use SQL Server

The Oracle stored procedure needs to be written recently, as required by the company. I am a novice, after the completion of the writing of the stored procedure, it is necessary to analyze the execution time of each statement in the stored procedure in order toOptimize the entire stored procedure.Due to the use of Plsql Developer client tools, and most of the internet is introduced by the manual method of applying the profiler, using relatively chores

A. Waitfortargetfps:Vsync (vertical sync) function, which displays the CPU wait time of the current frameB. Overhead:Profiler overall time-the total record time for all items. Used to record unclear time consumption to help further refine profiler statistics.C. Physics.simulate:CPU elapsed time of the physical simulation of the current frame.D. Camera.render:CPU consumption of the camera rendering readinessE. Rendertexture.setactive:Sets the rendertex

Problem description The Unity project often chooses to use Lua as a more logical script in practice. This is because Unity itself is less friendly to heat, more flexible with Lua heat, and simpler to share code and data with the server. At present, many different Unity + Lua integration programs, the practice of using a lot of Pang classmate's Slua program. Teams that use Lua tend to be "heavier" integrations, exposing a sizable engine interface to Lua, so logically enough freedom to have full

large problem is divided into multiple thread block processing, each block of the number of threads is not too small, like this article only 1 threads, which is a huge waste of hardware resources. An ideal solution is to divide n thread blocks, each with 512 threads, to decompose the problem, often more efficiently than a single thread parallel processing or a single piece of parallel processing. This is also the essence of CUDA programming. The above analysis of the performance of the method

Usually debug SQL, using Profiler used to, but now with a machine does not have Profiler installed, and tried to install again, add new features, but no profiler options, recently debugging really can not bear to see the code logic debugging, so the internet search, found a solution, put here, As an alternative:In the case of a SQL Server installation package, us
