Queries Builder (query Builder)
1. New data
You can insert one/more data by using the Insert method of the Query Builder:
Db::table (' users ')->insert ([
[' ID ' =>1, ' name ' => ' laravel ', ' email ' => ' laravel@test.com ', ' password ' => ' 123 '],
[' ID ' =>2, ' name ' => ' Academy ', ' email ' => ' academy@test.com ', ' password ' => ' 123 '],
[' ID '
The
intention is to separate the construction of a complex object from its representation so that the same build process can create different representations.
Applicability
When creating complex objects, the algorithm should be independent of the parts of the object and how they are assembled.
When the construction process must allow the constructed object to have different representations. Understanding The builder model is primarily to separa
The factory class pattern provides the pattern of creating a single class, while the builder pattern is to centralize the various products to manage, to create composite objects, so-called composite objects that refer to a class that has different properties, in fact the builder pattern is the combination of the previous abstract factory pattern and the last Test. Let's look at the code:As before, a sender
Builder mode, which separates the construction of a complex object from its representation, this allows you to create different representations for the same construction process. If you need to separate the construction of a complex object from its representation, you can create different tables during the construction process, we need to apply the "Builder mode", also known as "generator mode", to applicab
Builder pattern Definition: Separates the construction of a complex object from its representation, allowing the same build process to create different representations.
The builder pattern is a step-by-step way to create a complex object that allows users to build them only by specifying the type and content of complex objects. The user does not know the specific build details inside. The
The builder mode also belongs to the creation mode.
As the name suggests, a builder is the person who implements a product (Building). After a series of unified operations, they can complete a work and what kind of product is inseparable from the builder. For example, the old Li family now has a land that can be used for building land. It can be used to build a s

Personal understanding of the application scenarioFor example, if you want to create instances of various types of cars, there are many types of cars, but the interface definition for creating each type of car may be the same, and this mode is used.Popular explanations of related concepts

The specific implementation of the interface to each type of vehicle is called co
Design Pattern Series (iii) the factory model is described in the article, the factory method model and the abstract factory pattern are introduced. This paper mainly introduces the design pattern of builderOverviewIn the software system, sometimes faced with the creation of "a complex object", it is usually composed of the child objects of each part by a certain algorithm; Because of the change of requirements, the various parts of this complex object often face drastic changes, but the algorit
"@" and then the function name, the symbol "@" and the number of bytes of the parameter are followed. For example, the modifier of the int func (int A, double B) function is @ func @ 12. For the "C ++" function, it is different.In the future, compilers may use different registers to store parameters.

Flash VS flex builderflash was acquired by Adobe when it was flash8, which is now available for as2 object-oriented. After being acquired by Adobe, Adobe is ready to turn flash into a development tool. For example, JBuilder, VS, and so on. Therefore, with Flex builder, it is literally like JBuilder. Therefore, it is a development tool and as3. It should be as3 after flash8. The original as2 designers suddenly felt that as3 had changed a lot, because t
