MySQL SQL Performance Analyzer
The SQL Performance Analyzer of MySQL is mainly used to display the usage of various resources during SQL Execution. Analyzer can better displayPoor SQL Performance problems.
How to use MySQL SQL Profile
1. Enable MySQL SQL Profile
Check whether MySQL SQL profile is enabledMysql> select @ profiling;+ --
I like to think of tools bundled with SQL Server as inverted pyramid type, tools for diagnosing and checking general problems at the top, finding and diagnosing problem-specific areas of the tool at the bottom. In addition to providing a convenient way to write SQL scripts, Query Analyzer is the resource you need to use when you need to address specific SQL scripts to clarify the problem. If you need to indicate which query is holding the lock on a pa

Before that, I tried a project to automatically generate the so extension for our PHP code,
Compile it into PHP. I call it phptoc.
However, the project is suspended for various reasons.
I wrote this article because there are too few materials. I also summarized my gains for future reference. If you can understand PHP syntax analysis

I like to think of the tools bundled with SQL servers as inverted pyramid. Tools for diagnosing and checking general problems are at the top, and tools for finding and diagnosing specific areas of problems are at the bottom. In addition to providing a convenient way to write SQL scripts, the Query Analyzer still needs to use resources when you need to solve specific SQL scripts to identify problems. If you need to specify which query is holding the lo
information in the symbol table. The latter three steps are the integrated section (also the backend back end), which constructs the desired target program based on the intermediate representation and the information in the symbol table.
The benefit of dividing the compiler into so many steps is to make each step simpler, making the compiler easier to design, or leveraging many existing tools-for example, the lexical analyzer can be generated with L
The main purpose of MySQL's SQL Performance Analyzer is to show how resources are used throughout the process of SQL execution. The parser can better demonstrate the performance problems of poor SQL.Here are some examples of how MySQL SQL Profiler is used:
First, turn on MySQL SQL Profiler

Today, we will introduce how to perform one-step debugging through the debugging function of the query analyzer. This is also a very practical technique. Q: How can I perform one-step debugging through the debugging function of the query analyzer? A: The specific steps are as follows: 1. Set the server [authentication] attribute to [hybrid mode] (window and SQL identity)
Today, we will introduce how to perf

The smaller the bandwidth, the more spectral resolution. However, there is a trade-off between what quickly the display can update the full frequency span under consideration and T He frequency resolution, which is relevant for distinguishing frequen
