I often look at the SQL Profiler trace and feel that it is not convenient to store it as a file. After storing it in a database table, you can simply query it. However, the eventclassid column in the saved table displays numbers, unlike the ones used in profiler.ProgramShown RPC: StartingSP: StartingSP: stmtstarting And so on. After searching online, I found the following script to display eventclassid as the name. SelectTe.Name,T.*From

Label:The role of replay tracking You can use a trace as a test tool, and when you call some stored procedures in the correct order, you will be able to regenerate specific failures. Tracking templates There are four options for saving a trace (file-to-Save As) 1. The trace files option is used to save the data in a binary format file, which is the fastest, and the least disk-byte-consuming method. 2. The trace table option is used to save the data to a new or pre-created table in the user-sele

What is the recommended way to loading.readobject the high cost? Loading.readobject is a resource-loading function for the unity engine that typically occurs when switching scenes and loading API calls, including textures, meshes, Material, Shader, Animationclip, and so on. If you find that the value is too high, it is recommended to vigorously optimize the associated resources for loading. For each type of resource loading, we are summarizing and sharing it in a thematic way, so we recomm

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

Map SQL Server Profiler eventclass ID to its name in a saved trace table If you 've ever worked with SQL Server Profiler then you're familiar with the eventclass column in the trace. It tells you what event is being monitored for each row. When you save this trace to a table you can see That the eventclass no longer has a description but an ID. So how do you map this to a description? If you know where

SQL profiler is a good thing. This greatly facilitates viewing the execution of SQL statements and helps us understand many internal SQL states. So there is no other way to implement it except to run SQL profiler? Of course not. Here is a simple example: 1. Use the system stored procedure sp_trace_create to create a trace. This SP can be found on-line help. Declare @ traceidout int, @ on bit, @ RC int-- Def

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
