Why is the filtered column value always 100% in Mysql explain extended?1. execute the Mysql explain extended command to output a column of filtered (MySQL5.7 outputs filtered by default ), it indicates the percentage of rows in the returned results to be read (the value of the rows column. Filtered is a very useful value, because for join operations, the result set size of the previous table directly affect

Chapter 2 generation algorithm based on division-test-extended real-value Detector This chapter aims to improve the performance of the PT-RNSA algorithm, introduce the extension strategy on the basis of division-test, put forward the algorithm based on division-test-extended real-value detector generation (PTS-RNSA: real-valued detector generation algorithm based on the partition-test-spread proess), and co

1. What is a regular expression and what is its function. Global Search Regular Expression and print out the line. Regular Expression: Regular Expression Engine Regular Expression:Is a type of character writing mode, many of which do not represent its literal meaning, but express control or wildcard functions, The text search tool performs a row-by-row search on the target file based on the text mode (Search Condition) specified by the user to display matching rows. Basic Regular Expression: gre

Euclidean algorithm is what we often say the method of greatest common divisor, the division method can be used to seek the greatest common divisor, know that the least common multiple can also be begged. GCD seems to have a library function __gcdint GCD (intint b) { while0) { 　　int r = b; = a% b; = r; } return A;}non-recursive methodint gcd (int A,int b) {return b? gcd (B,A%B): A;}Recursive methodThe extended Euclidean algor

0 , Euclid's theoremThe basis of all, nature is Euclidean theorem. Its form is very simple (sometimes naive)gcd (A, a) =gcd (b,a mod b)Prove: Suppose a , the number of conventions for B is g, and $${a}={bx+y}{(x,y\in Z)}$$ There is obviously $${g \mid A},\qquad {g \mid b},\ Qquad{{a}\ mod\ {b}}={y}$$ $${\because g \mid b}$$ $${\therefore g \mid bx}$$ and $${\ Because G \mid a}$$ $${\therefore g \mid {(A-BX)}}$$ i.e. $${g \mid {{a}\ mod\ {b}}}$$ so g is b and a mod b th

This article mainly introduces the Laravel extended memcached cache driver implementation using the Aliyun OCS cache, this article extends a support SASL authentication mode memcached cache driver, need friends can refer to the following Laravel is I recently used a lot and the more I like a PHP framework, because there is no backward-compatible historical baggage, fully object-oriented style, with the help of facades elegant IOC Container implementa

Enterprise Linux 6, and the remaining versions are not fundamentally different. 1. Start VMware Program, click "Edit Virtual machine settings", as shown in the following figure. 2. In the pop-up dialog box, click on the "Hardware" tab, you can find hard disk space size of 20G, click on the right side of utilities, select "Expand". 3. In the Next pop-up dialog box, select the maximum size of the hard drive, set to 30G here, click the expand button. 4. Extending the hard disk space takes a

In SQLServer, you can use extended stored procedures to implement remote database backup and recovery. For more information, see SQL Server implements remote database backup and recovery through extended stored procedures. For more information, see This article explains how to extend the stored procedure of SQL Server database through examples to achieve remote backup and recovery. Instance description: E

During this period, when purchasing storage and communicating with many storage vendors, we mentioned that it supports dynamic expansion of storage capacity. For example, if the original storage capacity is 5 TB, A lun will be allocated. Later, due to business needs, it will need to be extended to 1. During this period, when purchasing storage and communicating with many storage vendors, we mentioned that it supports dynamic expansion of storage capac

On the extended Euclidean algorithm (Extended Euclidean algorithm), I was working on the classic topic of frog dating to get access to this algorithm. There is also an AC code and a solution to the problem.Content: Known A, B, solves a set of X, Y, and satisfies the Bézout equation: Ax+by =gcd (A, B)Extending Euclid's algorithm, like its name, is an extension of Euclid's algorithm. What is an extension? Fir

SQL Server's extended storage process is actually a common WindowsDLL, but some functions are implemented according to certain rules. Recently, when writing an extended storage process, I found that there are still some important points to note when writing this kind of dynamic library. Note that the DLL runs in the address space of SQLServer. SQL Server's extended
