SQL Server Profiler--Identify exceptionsIn a perfect environment, all anomalies should be captured, processed, and recorded. A person regularly views these logs and creates error reports based on the exceptions that occur, so that they can be debugged in a timely manner and can avoid recurrence in the future. However, it is always possible to see that the application is constantly seeing various exceptions from the database to the user interface, and

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 ...... 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

The JVM is a virtual machine and a specification, and he follows the design principles of the von Neumann architecture. Von Neumann architecture, it is pointed out that the computer processing data and instructions are binary number, using stored procedures to store in the same memory without distinction, and sequential execution, instruction by the operation code and address code, the operation code determines the type of operation and the number of

19.2.1 Understanding SQL Server Profiler SQL Server Profiler is a graphical real-time monitoring tool that helps system administrators monitor the behavior of databases and servers, such as the number of deadlocks, fatal errors, and the tracking of Transact-SQL statements and stored procedures. You can store these monitoring data in a table or file, and then display the events again at a later time to anal

Do development, usually inevitably and database dealing with, especially write stored procedures, for those of us who do not often write SQL is a very painful thing, every write run is always wrong, if the use of the local database is OK, you can debug SQL in this machine, if the database on the server, debugging is disabled, It's tragic.Recently, due to job requirements, write a stored procedure, there are dozens of parameters, the database on the server, finished, test the query is not a probl

JVM Stack resolver operation problem, that is, how the program executes, or how to process the data; The JVM heap solves the problem of data storage, where the data is placed, where it is placed, and what is stored in the JVM heap is the object. The JVM stack is a reference to the base data type and the objects in the

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

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
