Http://www.linuxidc.com/Linux/2012-08/68035.htm1. IntroductionIn a relational database, a join operation is a very common practice when combining data from different tables. Let's start by looking at how joins work, and then we'll explore the order of execution when the join and where statements are present, and finally talk about the order of the different types

For our site structure, we look at the weight of the flow, we can compare it to is a big tree. Our site's leading navigation bar is our roots, and bread crumbs, classification is the trunk, as for our content page is the foliage of this tree. So how do we make our site weights can be rationally assigned to our roots, trunks and foliage? This requires us to have a perfect site structure design. So how do we design our site structure to achieve the best optimization results? The author of this art

Linux files are basically divided into three properties: readable ( R), writable ( W), executable ( x) (Take -rwxr-xr-x as an example): Rwx (Owner) r-x (Group) r-x (Other)The permissions represented are: The user is readable, writable, executable, the same group of users can be read, not writable, executable, other users can read, not write, can be executed.chmod [-r] XYZ file or directoryXYZ is the sum of three rwx attribute valuesThe numbers in the same group are added! If the property is [-r

See an article on your Web site: "Insert different types of objects in an STL list (Lists)." I feel that the answer has not pointed out the nature of the problem, so I put forward my point of view, I beg to correct. I think that the cause of the error is the pointer transformation process, the program did not point out the original prototype of the pointer, or, because did not find the correct subclass func
