course, because of my personal ability and experience, my own kind of anatomy will produce a variety of deviations or paranoia in the process. So The best way, is to invite other colleagues, peers together on the autopsy table, to their own ideas, to ensure that the knife accurate, direction correct, so that their needs analysis of the exercise process, more with the wisdom of the masses and reference value. Anyway, I think,Product people is to con

SQL injection is a very deep learning, but also a very technical knowledge1. Introduction of Operator Precedence2. Introduction to SQL statement execution functionmysql_query () returns a resource identifier only for Select,show,explain or DESCRIBE statements, or FALSE if the query is executed incorrectly.For other types of SQL statements, mysql_query () returns TRUE on successful execution and returns FALSE on error.A return value other than false means that the query is legitimate and can be e

can finally draw a panorama picture. Since the B + Tree of the secondary index has a similar structure to the primary key index, only the structure of the primary key index tree is drawn, including the green and yellow parts of the primary key non-leaf node and the primary key leaf node. Restore it to the more concise tree below, which is part of the B + tree. Note that there is no one by one relationship between page and B + tree nodes, page is just a save container for a record, it exists to

. This is mainly based on several reasons: 1 principle is the cornerstone, only have a full understanding of how the InnoDB index work, we have the ability to effectively use it. 2 The principle of knowledge is particularly suitable for the use of illustrations, I personally like this way of expression. 3 about InnoDB optimization, in the "high-performance MySQL" has a more comprehensive introduction, to optimize MySQL interested in the students are fully able to obtain relevant knowledge, my ow

Note: The entire c Standard Library anatomy series environment is Ubuntu 8.04, the compiler is GCC 4.2.4, because the Linux system only has c Standard Library header files (under/usr/include ), the function library is compiled into a library without source code. Therefore, glibc 2.9 is used for source code anatomy and can be downloaded from the GNU official site.Types include limits. H, float. H, stddef. H,

Detailed Anatomy of bash script programmingbackground: bash scripting is a crucial part of Linux learning, and it may be easy to complete a script, but it's not easy to make your own script write. Bash is almost always available for all Linux distributions, so let's take a bash script as an example to discuss how bash scripting is written. For some of the more important points in bash scripting, I'll give you a case demonstration. I. Script programmin

"it gives us the ability to conquer other hills," which may be called sharpening. Of course, the choice of what kind of hill to training, from our own interests. From a basic point of view, we can choose other hills of interest to conquer, such as the Massachusetts Institute of Technology XV6 operating system, and not necessarily choose the UCC compiler. XV6 operating system is UnixV6 system on the X86 platform of rebirth, if time permitting, perhaps we can go together "XV6 Operating system
