updating data and deleting data. If you change the column in the WHERE clause in the update and delete to B, the speed is the same as no index because the index is invalid. Therefore, the index can greatly increase the query speed, for delete and update operations, if the column in the WHERE clause uses an index, even if the index needs to be re-build, it is likely that the speed is faster than not using the index. The index is obviously a burden on the insert operation. At the same time, the i

Cookies are a technique that allows a Web server to store small amounts of data on a client's hard disk or memory, or to read data from a client's hard disk. When you browse a website, your hard disk will produce a very small text file, which can record your user ID, password, visited pages, time of stay and other information.When you come to the site again, the site by reading cookies, learn about your information, you can make the corresponding action, such as on the page display welcome your

little accident, very disappointing.But the project couldn't stop, so we started analyzing the code, checking it several times and discovering that the code was fine.We started Google.Well, I found out why. It is only when the page submits that the change is submitted, which is also a problem-solving direction. But we want to change it when we're not submitting the page, and we're thinking of using JavaScript to solve the problem.This is the TreeView

The Code jumps to the latest statement next to the back of the loop and continues to run downward. In. net, the GOTO statement can directly locate the specified mark as continuing to execute the code, but there is no GOTO statement in

The simplest is macro expansion, which is clever:   # Include # define A (x) x; int main () { int n = 1; A (printf ("% d", n ++); return 0; }   More advanced is to use the constructor feature of C ++ -- the constructor is called by default

Example 1: # Include # include int main (void) {char STR [256]; scanf ("% s", STR); If (strlen (STR) Example 2: # Include int main (void) {int I = 0; while (1) {I ++; printf ("% d \ n", I ); if (I = 10) goto AAA;} AAA: printf ("OK! \ N ")
