1. What is bad database blocks? First, let's take a rough look at the format and structure of the database block-The database data block has a fixed format and structure, divided into three layers of cache layer, transaction layer, data layer. When we read and write data blocks, the database will check the consistency of the data blocks to be read and written, i

Before you do this, you need to install some of the necessary software first.GCC is installed by default under Ubuntu, but the required header file is missing, and you can install the Build-essential suite by entering the following command on the commands line:sudo apt-get install build-essentialTo install the GTK Dev kit using gtk+2.0, enter the following instructions on the command line to install the GTK dev Kit Libgtk2.0-dev:sudo apt-get install Libgtk2.0-devAfter the installation is complet

The first two days to try to use Vim+gcc+gdb to write C language, but for me such a novice is too painful, not to, to the IDE, find a half-day, chose the code blocks this is the most used by everyone. But when it's running:Flash past, Debug time also catch no breakpoint, also does not display the console, the internet looked for a bit, there are currently several solutions:(1) First, all the paths cannot have Chinese and cannot have spaces.(2) Second,

One, the statement of the blockblock is declared after the function call, using the {..} Enclosed, or do.. End encapsulation. {} is typically used on single-line statements, do ... End is used on multiple lines of statements. (1..4). each{|v| print "#{v}"} #输出1 2 3 4 Blocks can be with parameters, unlike function parameters, block parameters with Encapsulation, of course, can take multiple parameters. How these parameters are defined i

Purpose1. Table scanning before index creation1. Which data blocks are scanned?2. Relationship between data blocks3. Physical read4. Logical read5. Test the differences: full table scan and partial Table Record Scan6. Do I scan data blocks for single-block reading, multiple-block reading, or multiple-block reading after one-block reading?2. Summary:1. Relationship between table scan speed and data block siz

Generally in this case, I like to ask myself: "If the question is to Apple, what will he do?" Of course, we all know that Apple certainly knows how to do this, because at one level, Apple's documentation is a guide to how we use design patterns. So we need to look at the circumstances in which Apple uses delegate and block, and if we find out how Apple makes this choice, we can build rules that can help us make the same choices in our own code. To find out where Apple uses delegate is simple,

-driven, modular design Direct use of custom tags such as , binding events, etc. in templates Build projects automatically using ScratScrat can be installed in a continuous integration system to automatically build the project, but also has the ability to build by version. Personal view The framework proposed by building blocks to develop the module, and finally the way to build the system is very good, before I developed projects are u

The optimizer must determine how to access the data that your SQL requires. The next step in generating an execution plan is to use the optimizer to determine the best way to access the data when the expression and condition evaluation of the SQL statement is closed, and all query transformations that may help to build the execution plan more accurately are executed. In general, there are only two basic methods of data access: Full scan and Index scan, and full scan may be a full table scan
