text on the screen is present, but requires a series of change techniques A number of sometimes tricky transformations to get the right behaviour. Well, during a recent internal To get the right results, after a recent internal discussion, Discussion I became aware of a really handy facility inside AutoCAD which allows you to dependably draw screen-fixed text Without jumping through hoops. I'm starting to realize that there's a really handy way in CAD content that allows us to get reliable, fix
In Oracle 11 g2, duplicating a database has two methods:
1. Active database duplication2. Backup-based duplication
The advantages of using duplicate for a database are:Test backup and recovery proceduresTest an upgrade to a new release of Oracle DatabaseTest the effect of applications on database performanceCreate a standby databaseGenerate reports
First, we will learn about Backup-based duplication, which is better understood. test environment: Same
Mysql development skills-JOIN update and data re-checking/de-duplicating; development skills-join
Mainly involved: JOIN, JOIN update, group by having data re-query/de-duplication
1 inner join, left join, right join, full join (not supported by MySQL), CROSS JOIN
This is a very good blog post on the Internet. The join statement is illustrated as follows:

Tonight read a predecessor wrote LINQ to the collection elements merge to repeat processing, feel a bit of trouble, the original address is as follows: Http://www.cnblogs.com/yjmyzz/archive/2012/12/18/2823170.html#undefined.So I figured I'd use the LINQ grouping function to write a method with the following code:Using System;Using System.Collections.Generic;Using System.Linq;Using System.Text;Namespace ConsoleApplication4{Class Program{static void Main (){listNew product{stocknum=1,productno= "t
Implementation idea: Create a js object and a new array. when traversing the input array, determine whether the value is the key of the js object. if not, add the key to the object and add it to the new array. NOTE: & amp; nbsp; when determining
The first method is more common. Ideas:1. Create a new array to store the results2. In the for loop, an element is extracted from the original array each time, and indexOf is used to find whether the element exists in the new array.3. If not, it is
The first method is the conventional method: Create a new array to store the results. In the for loop, each time an element is retrieved from the original array, indexOf is used to find whether the element exists in the new array, for the second
Method 1: extract JQ (source network). This method is complete.
Array.prototype.unique = function(){ var results=this.sort() for ( var i = 1; i
Method 2: complete method.
Array.prototype.unique = function(){ var newArray = [],
