The online business uses the ORM framework, and discovers a slow query SQL that has been sorted two times in the same field, resulting in filesort. The ORM Framework has its own table structure as follows: CREATE TABLE ' Unopen ' ( ' Corp ' tinyint (3) unsigned not NULL DEFAULT ' 0 ', ' invtype ' tinyint (3) not Null default ' 1 ', ' uid ' int (a) NOT null default ' 0 ', ' username ' char (+) NOT null default ' 0 ', ' Fatid ' int (a) NOT

The example in this article describes the time difference method for the go language to calculate two times. Share to everyone for your reference. The specific analysis is as follows: The go language calculates the time difference of two times, the code is very simple, return 1 days ago, 1 weeks ago or January ago time Package main Import ( "FMT" "Time" ) func main () { //add method and sub method

argue about similar geometric theorems, they are based on this hypothesis. As an example, they have proved the theorem that the ratio of the area of the equal-height triangle equals the ratio of their bottom. As shown in Fig. Two triangular abc and ADE, their bottom side BC and De are on the same line MN. Thus the two are equal in height. Then the Pythagoras school proved the ratio of the area to the corresponding bottom by the following way. Because all the amount can be public degree, so ac

This tutorial mainly uses Photoshop to pull out the wedding movie dream blue background effect, addition two times composition is refers to use the space or the material form to adjust the original picture composition, finally achieves a reasonable composition form.

Oracle database tests for these three languages. In the cyclic performance test, JSP uses a 20000*20000 loop for a total of four seconds. And the ASP, PHP test is the 2000*2000 cycle (one less order of magnitude), respectively, in 63 seconds. PHP tests the 2000*2000 loop for 84 seconds. In the database test, the three Oracle8 are insert,update,select and delete 1000 times respectively: JSP takes 13 seconds PHP takes 69 seconds ASP takes 7

This relies on the OnNext function to be triggered multiple times when a button is clicked. This is the jquery internal does not determine whether to bind multiple times, suspected that its internal use of an array to save event functions, and does not go heavy. Th

Recently in a project, need to read the Tex file, but the function of each call, open a file, after the call will find that the call will not open the file, the data is not read at all, and then take a most stupid method, each call function re-use fopen open a file, and finally really crazy, Find the information on the Internet, understand the principle. When we use a pointer to open a file, it is through the movement of the pointer to read the data inside, if you use this pointer again, you hav
