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

NHibernate Profiler is a tool that can monitor SQL statements in NHibernate1. Download NHibernate Profiler2. Add a reference to your NHibernate project (below the NHibernate Profiler root directory)HibernatingRhinos.Profiler.Appender.dll3.

P6spy combined with SQL profiler Configuration P6spy is a dynamic monitoring framework for database access. It has been very mature for a long time. p6spy simulates a standard JDBC driver and acts as a proxy for the real underlying JDBC driver. That is to say, we only need to configure the JDBC driver used in the system as the p6spy driver, and configure the realdriver in the p6spy configuration as the actual JDBC driver, so that we can use its p

SQL Server Profiler is a performance monitoring tool for MS SQL. You can use this tool to find the SQL statements to be optimized, and then use the database engine optimization advisor tool to help optimize the database. SQL Server Profiler usage Click Start -- program -- Microsoft SQL Server 2005 -- performance tool -- SQL Server Profiler For example The

As a performance tool of the Microsoft SQL Server database series, SQL Server Profiler can track the running status of databases in real time and find slow queries or deadlocked SQL statements, to optimize the system. This article describes how to use Silverlight to monitor SQL Server Profiler in real time (the database environment uses SQL Server 2005 as an example) First, let's take a look at the SQL Ser

In use. NET to start and develop the application quickly, the next problem may be the performance tuning aspects of the program, and performance tuning can sometimes involve all aspects of the problem, such as the program host system, database, network environment, and so on, and when the program is unusually large and complex, performance tuning will become even more impossible. This series of articles will mainly introduce some. NET performance tuning tools, Web performance optimization rules

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

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

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 ......

However, the native Web-inspector only gives the JS function's execution occupancy ratio, and does not list whether the function has been optimized, and if not, what the reason is.After reading the JS engine V8 code, we present these very critical/useful information to the code farmer thr

Some time ago, I had a performance problem with my website, and sometimes the page was very slow to open. It would take more than 10 seconds. I tried a lot of methods, including cache, disable viewstate, and Disable debug mode. The improvements were not obvious. Later, I ran into SQL Server Profiler to check the cause: a slow query dragged down the entire page. Later, the query was optimized, but not many improvements were made. Finally, an index i

SQL Server Profiler provides a blocked Process report event, which records blocking tasks that exceed the specified time. With this event, we can record the blocking information of the database. Next let's take a look at how to use blocked processreport: To use blocked Process report, you must configure the threshold and report generation frequency. Use the sp_configure command to configure the blocked process threshold option (in seconds ). By defa
