Transferred from: http://blog.csdn.net/joshua_peng1985/article/details/6213593 Introduction Materialized views are a special physical table, and the materialized view is relative to a normal view. Normal view is a virtual table, the application of a large limit, any query on the view, Oracle is actually converted into a query of the views SQL statements. This improves overall query performance without subst

What kind of communication can make information symmetrical? In fact, the simplest way to let information symmetry is replication, unfortunately, even if the human brain can not be turned into a computer, so communication becomes the only way, language is the way of communication between people, the Web page is the server and the user's way of communication. Normal: elements are always displayed on the page;transient: elements need mouse hover, click

5.2 MySQL server log---------------------mysql log types: 1. Error log: Problems encountered when starting, running, stopping mysqld 2, common query log: establishing client connections and receiving from clients Received statements 3, binary log: Change the data log (also used for [master-slave] replication) 4, Relay log: Master-slave replication, the main server will own binary log sent to the server, called the relay log 5, slow query log: Execution time over Long_que Ry_time query 6, DDL

When lighting was enabled in OpenGL, the normal vectors was used to determine how much light was received at the specified V Ertex or surface. This lighting processing was performed at the eye coordinate space, therefore, normal vectors in object coordinates was also TR Ansformed to eye coordinates with Gl_modelview matrix.When the illumination function is activated in OpenGL, the

First of all, thanks to the szy-8910 blogGeneration of Normal Distribution Random Numbers The excerpt is as follows: Ii. Generation of random numbers distributed randomly The following describes how to generate random numbers with known probability density functions. A typical normal distribution is used as an example to generate random numbers with arbitrary names. If a random number sequence follows a o

Word-break: normal | break-All | keep-allParameters:Normal: line breaks are allowed according to the text rules of the Asian and non-Asian languages.Break-ALL: this behavior is the same as that of the Asian language normal. It also allows non-Asian text lines to be broken in any word. This value is applicable to Asian texts that contain non-Asian texts.Keep-ALL: same as

Shaanxi Normal University is a key construction university directly under the Ministry of Education and the State's "211 project". It is an important base for the state to train instructors and education management cadres in universities and secondary schools, known as the "cradle of teachers" in northwest China ". Founded in 1944, the school was formerly known as Shaanxi Provincial Normal College. In 1954,

CPU in the computer running process will be hot, if not timely cooling, with the accumulation of heat caused by burning the CPU. This requires the configuration of the CPU fan exhaust fans to speed up the flow of air through the fan, the heat emitted in time. While the CPU fan has a thermal sensor, when the temperature reaches a certain setting area, the fan adjusts the speed through the sensor, causes the CPU temperature to maintain in the reasonable interval. How much CPU speed is

use inline to define inline functions, however, any letter defined in the description section of the class Numbers are automatically considered to be inline functions. 　　 Let's introduce the use of inline functions. Inline functions must be declared with the function body to be valid. A statement like this Inline tablefunction (int I) is not effective, the compiler simply takes the function as an ordinary letter Number statement, we must define the function body. Inline tablefunction (int

Hello everybody, I am the Harbin actual situation website design, recently because of work reasons, rarely write anything, today is OK, out of the surface, recently found that everyone in the Baidu adjustment, my site has also been greatly affected, the keyword crawl is not normal, the rankings fluctuate a lot, a few samples a day, snapshot update is also very slow, Hurrah is the snapshot and the time is not unified, some keyword snapshots are the mos

Places to be aware of:1. Use the gltranslate* function or the glrotate* function to change the appearance of the object, but the normal vector does not change with it. However, using the glscale* function, varying degrees of scaling for each axis, is likely to lead to incorrect normal vectors, although OpenGL provides some steps to correct the problem, but it also brings a variety of overhead. Therefore,

In the design of the database, often do not take into account the problem of table partitioning, often in the burden of the data table load is getting heavier, will take into account the partitioning method, at this time, it is related to how to convert the ordinary table to the problem of the Component table.So, how do you convert a normal table into a partitioned table? In the final analysis, simply create a clustered index on the table and use the

Definition of normal subgroup:Group H is a subgroup of G, if any of the a∈g, have AH = Ha, then the H is a normal subgroup of G, recorded as h? G.Examples of normal subgroups:1. Special linear groups are normal subgroups of general linear groups.2. Staggered groups are normal
