Introduction to MySQL Formatter

Hadoop, Data Science, Statistics & others

How Formatter Works in MySQL?

MySQL Formatter is an impressive and freely accessible tool for formatting MySQL code. It performs automatic refactoring of query code and provides various other functionalities and services to simplify tasks.

This formatter or organizer tool is essential to make the query follow all the critical standard rules and syntax code to build up an error-free and valid MySQL program.

Using the MySQL Formatter, a user can update the case of the MySQL keywords and identifiers used in the MySQL queries to either upper or lower case or keep it as they are.

It minimizes a programmer’s time typing the query in the editor tools providing an auto-completion option.

MySQL GUI tool offers intelligent service with MySQL prompt option to customize and organize the syntax highlighting as well as check and other abilities to permit you to write and check MySQL query codes more excellently and naturally.

The code completion has many features essential for MySQL formattings, such as list members, phrase completion, word completion, parameter data for stored functions, and fast info about schematic objects. So that you need to type fewer and more code can be written.

Code snippets are available to help save time in the suggestion list, along with keywords and table names, which are based on the symbol typed by you.

MySQL formatter is an effort to keep your code clear and clean like with CRUD generator; you can produce code scripts for any operations INSERT, SELECT, UPDATE, or DELETE.

Also, a user can get an error-free code and correct options to write valid code before execution. With the Automatic syntax check feature, while writing the code, if found any errors then, it will be highlighted there.

A user can get access to navigate the definitions of schematic objects or variables.

Once you complete the formatting process, you have the option to download the file or share the link. This simplifies, optimizes, and facilitates your MySQL code.

Rules for MySQL Formatter

Let us see some guidance to allow MySQL naming agreements with capitalization while conducting MySQL Formatting on any tool. Many formatting options help to accomplish capitalization steadiness.

The following rules describe how to achieve clean formatting of queries and ensure valid code:

1. Naming Rules for Database Identifier

Developers use identifiers to designate object names in a database, and they create these identifiers when defining a database object correctly. Suppose the succeeding MySQL statement will create a database table with the identifier as TableA and a table column with the identifier as ColumnKey.

Code:

CREATE TABLE TableA (ColumnKey INT PRIMARY KEY) 2. Capitalization Rules for Database Identifiers 3. Naming Rules for Variables

The variable names should start with the symbol @ along with the universal naming standards. But we should not apply @@ symbols to prefix a variable. Because this can hamper the performance as this prefix to a variable is implemented as a SQL Server system global variable.

4. Capitalization Rules for Variables 5. Capitalization Rules for Keywords Example of MySQL Formatter

Others Like: Code Beautify SQL Formatter, SQL Format, chúng tôi Instant SQL Formatter, etc.

Another Formatter tool for MySQL can be dbForge Studio for MySQL which has an auto code completion feature and many other capabilities to enhance the beautifying of the queries written in MySQL. It offers code snippets, code profiles, CRUD generators, syntax checkers, and schema objects to facilitate the implementation and execution of structured, clean, and error-free code for the desired operation in the MySQL server.

Conclusion

When we write any MySQL query, it must be properly valid without avoiding the rules and syntaxes so that different MySQL formatters can provide a sensible and correct statement. This process requires the MySQL formatting technique to produce well-defined and structured queries for the developers or programmers.

Learn How Concat Function Works In Sqlite?

Introduction to SQLite concat

Hadoop, Data Science, Statistics & others

Syntax

Now let’s see the syntax of concat () function as follows.

Explanation

strg_1: It is used for the first string to concatenate.

strg_2: It is used for the second string to concatenate.

strg_N: It is used for the nth string to concatenate and this string is an optional part of this syntax.

How concat function works in SQLite?

Now let’s see how concat () function works in SQLite database as follows.

Examples

Now let’s see the different examples of SQLite concat () function as follows.

Suppose users need to add first name and last by using the concat function. At that time we can use the following statement as follows.

Explanation

Explanation

Example

Explanation

Explanation

Now try to create a concat string from the table, so first we need to create a new table by using the following statement as follows.

create table student ( student_id integer primary key, first_name text not null, last_name text not null, address text not null, contact_no text not null unique );

Explanation

In above example we use create table statement to create new table name as student with different attribute such as student_id with integer data type and it assign as primary key of student table, first_name with text data type and not null constraint, last_name with text data type and not null constraint, address with text data type and not null constraint and last attribute is that contact_no with text data type and not null and unique constraint. The end out of the above statement we illustrated by using the following screenshot.

Now we need to insert some records to implement concat () function by using the following statement as follows.

insert into student (student_id, first_name, last_name, address, contact_no) values (1, "Johan", "Sharma", "Mumbai", 1234567894), (2, "Sunny", "Gupta", "Kolkatta", 1115598451);

Explanation

In the above example we use insert into statement to insert new records into the student table here we insert multiple records as in single query as shown in above statement. The end out of the above statement we illustrated by using the following statement.

Now we can see inserted records by using a select statement as follows.

select * from student;

In the above statement we use a select clause to display the records from the student table. The end out of the above statement we illustrated by using the following screenshot.

Now we have records, so we can try to implement concat () function by using the following syntax as follows.

Syntax

Explanation

In the above syntax we select statement to implement concat () function here order by clause is option part of this syntax and new colm name is used to assign new value into that column.

Example

Explanation

Conclusion

We hope from this article you have understood about the SQLite concat () function. From the above article we have learned the basic syntax of concat () function and we also see different examples of concat () function. We also learned the rules of concat () function. From this article we learned how and when we use SQLite concat () function

How Apply Works In Kotlin With Examples

Introduction to Kotlin apply

Web development, programming languages, Software testing & others

Syntax

In kotlin language, it has a lot of functions, classes, and other keywords for utilising the kotlin logic in the application. Like that, apply is one of the scope functions that can be used to configure the object once initialized and returns the object itself.

class name{ var vars:datatype; fun demo(){ ---some logic codes depends on the requirement— } } name().apply{ ---some codes--- }.demo()

The above codes are the basic syntax for utilising the apply() method in the kotlin class object initialization and return type.

How does apply work in Kotlin?

The kotlin application has some default functions that can be used to approach the top-level site in the file. It is needed for to create the class in to hold the reference of that class method. Kotlin apply is one of the extension functions that can be used on any of the types it runs on the object reference that can be of receiver format into the expression, and it returns the object reference. The apply function is similar to the run functionality, and it is only in terms of referring to the context of the object using “this” and other keywords like “it” in providing the null safety checks.

Apply keyword used in many cases that can be used with various scenarios, and it should be returned with an instance of Intent and an Alert dialog, etc. When we add the specific attributes in the application to them, it can be improved approach from the code snippet helps avoid variable names. The redundancy it thereby enhancing the code readability and the principle of code cleaning. We can see the other keywords and similar methods like run that accepts the return statement whereas the apply that does not accept a return object.

Examples of Kotlin apply

Given below are the examples of Kotlin apply:

Example #1

Code:

class Firstclass { infix fun demo(s: String) { } fun example() { this demo "Please enter your input types" demo("Sivaraman") } } class Worker { var workerName: String = "" var workerID: Int = 0 fun workerDetails(){ lst.add("Employee Name is: XX, Employee ID is:001") lst.add("Employee Name is: XA, Employee ID is:001n") lst.add("Employee Name is: YB, Employee ID is:002n") lst.add("Employee Name is: YC, Employee ID is:003n") for(x in lst) print("The employee lists are iterated and please find your output results $x ") } } { Worker().apply{ this.workerName = "First Employee is Sivaraman" this.workerID = 52 }.workerDetails() data class First(var inp1 : String, var inp2 : String,var inp3 : String) var first = First("Welcome To My Domain its the first example that related to the kotlin apply() function","Have a nice day users","Please try again") first.apply { chúng tôi = "Welcome To My Domain its the first example that related to the kotlin apply() function" } println(first) with(first) { inp1 = "Please enter your input types" inp2 = "Please enter your input types" } println(first) }

Output:

In the above example, we performed the employee details using the default methods.

Example #2

Code:

interface firstInterface { val x : Int val y : String get() = "Welcome To My Domain its the second example that related to the kotlin also() method" } interface secondInterface { fun Sample1(){ println("Your Sample1 Method") } } class Second : firstInterface, secondInterface { override val x : Int get() = 52 override fun Sample1() { println("Have a Nice Day users please try again") } private val res = "firstInterface Second" fun eg() = "This is the second we discussed regarding kotlin also() method" } class Business { var bName: String = "" var GST: String = "" var Location: String = "" var year: Int = 0 fun enteredNewEmployees(bn: String, gst: String, loc: String, yr: Int) { bName = bn GST = gst Location = loc year = yr println("Please see the below new business name: $bName") println("Please see the Business id: $GST") println("Your Location is: $Location") println("The Cross year of the new business is : $year") } fun NewBusinessName(bn: String) { this.bName = bn } } { data class Car(var carName: String, var CarModel : String) var nw = Car("Benz", "AMGE53") nw.apply { CarModel = "RangeRover Evoque" } println(nw) nw.also { it.CarModel = "Audi A6" } println(nw) val ob = Second() ob.Sample1() var ob1 = Business() var ob2 = Business() ob1.enteredNewEmployees("VSR Garments", "33ACKPV67253278", "TUP", 1994) ob2.NewBusinessName("Raman") println("bName of the new Business: ${ob2.bName}") val s = Second() println(s) println(s.eg()) }

Output:

Example #3

Code:

{ data class Third(var str1: String, var str2 : String) var third = Third(“Siva”, “Raman”) println(“Welcome To My domain its the third example that related to the kotlin apply() method”) third.apply { str2 = “Sivaraman” } println(third) third.also { chúng tôi = “Dell” } println(third) with(third) { str1 = “Sivaraman is the Employee working in XX company” str2 = “He is using the DELL Laptop which provided by his office” } }

Output:

In the final example, we used default methods like also(), apply(), and with() methods for to perform the user operations in the application.

Conclusion

In kotlin language has some default scope functions for performing the operations in the kotlin application. Moreover, it has some default extension functions for doing something with an object, and it returns the value. Also, if we need to perform some other operations on an object and it returns some other object, we can utilise it.

How Stack Works In Docker With Examples?

Introduction to Docker Stack

The ‘docker stack’ is a Docker command to manage Docker stacks. We can use this command to deploy a new stack or update an existing one, list stacks, list the tasks in the stack, remove one or more stacks, and list the services in the stack. Stacks can only be deployed in Docker swarm mode, which comes bundled with the Docker engine, eliminating the need for additional package installations.

Start Your Free Software Development Course

Web development, programming languages, Software testing & others

Syntax: 

docker stack [OPTIONS] COMMAND

Options:

deploy: It is used to deploy a new stack or update an existing stack

ls: It is used to list stacks

ps: It is used to list the tasks in the stack

rm: It is used to remove one or more stacks at the same time

services: It is used to list the services in the stack

We can use the ‘–help’ option to learn more about this command, as shown below:

docker stack --help

We can get more information on any of the above commands using the ‘–help’ command as shown below: –

docker stack deploy --help

How Stack works in Docker?

We must pass a ‘docker-compose.yaml’ file as an argument to the ‘docker stack deploys’ command using the ‘–compose-file’ or ‘-c’ option. The ‘docker-compose.yaml’ file comprises services, volumes, networks, and other necessary configurations to launch a comprehensive application. The Docker daemon adds a stack name before service, volume, or network names.

The Docker images mentioned in the compose file are either available on any Docker registry, it might be a private or public registry, or available on all nodes in that swarm, otherwise, container creation will fail.

Examples

Let’s create a simple Python application and deploy it in a Docker Swarm.

First of all, create a local Docker register running as a service using the below command:

docker service create --name my-registry -p 5000:5000  registry:2

Note: We need to initialize the Docker swarm (if not initialized already) using the ‘docker swarm init’ command before running the above command.

Now, let’s verify that the service is running fine and the registry is accessible, as shown below:

docker service ls

Explanation:  We can see that the service is replicated and can access the local host successfully.

Let’s work on the application now; we are going to create a Python application with the code mentioned below, however, we can use any application: –

test-app.py

Code:

app.run(host=”0.0.0.0″, port=8000, debug=True)

We have used Flask and Redis in our Python application, so we need those packages to run the application, so here is the chúng tôi file that we are going to use while building the Docker image.

Here is the snippet of Dockerfile to build a Docker image: –

Dockerfile

CMD [“python”, “test-app.py”]

Let’s build the Docker image now and push it to the local registry as shown below: –

docker push localhost:5000/test-app

Let’s create the ‘docker-compose.yml’ file with two services: ‘web’ and ‘redis’.

docker-compose.yml

image: redis:alpine

Finally, deploy our first Docker stack using the above ‘docker-compose.yml’ file and name it ‘my-first-stack’ as shown below: –

docker stack deploy --compose-file chúng tôi my-first-stack

The given example shows that the services and networks have been labeled with the stack name.

Let’s check if it is deployed successfully using the ‘docker stack ls’ command as below: –

docker stack ls

We can use the below command to know more about services running under this stack: –

docker stack services my-first-stack

In the above snapshot, we can see that 1 replica is running out of 1 for both services. Suppose there is 0 replica showing, which means that the service is not deployed successfully. Check the containers and their logs to troubleshoot.

docker stack ps my-first-stack

Let’s test the application by connecting to it as shown below: –

Hurray, we are able to access our application. Let’s do other ‘docker stack’ commands.

docker stack rm my-first-stack

Based on your description, in the provided snapshot, it appears that all services and networks created during the deployment of the stack are being removed.

Advantages

It makes it easier to manage all components of an application.

We can deploy a highly available application using the Docker stack as it works in Swarm mode.

We can use different orchestrators like Kubernetes as well.

Conclusion

We use ‘docker stack’ most of the time while deploying applications in production to make them highly available. It only works in Swarm mode, so we must have to activate or initialize Swarm mode.

How Instagram Search Works: Explained In Detail

Instagram Search: Explained in Detail (2024)

In the blog post, Mosseri explained a few significant features that the Search functionality on Instagram leverages to deliver relevant search results while keeping them safe for the users. So, when a user searches for a certain topic or account on Instagram, the company makes sure they get the most relevant results curated for them.

Ranking Search Results

The first thing that Instagram Search does is rank the search results based on their relevance to the users. To do this right, the platform leverages other data from accounts, hashtags, and places, which are essentially called Signals, to rank and curate the search results of users.

Your text in Search – One of the primary elements on which your Instagram search results will depend is the text you enter in the search field. So, once you start typing texts into the search bar on Instagram, the search tool matches relevant usernames, places, and bios to deliver appreciable search results.

Your Activity – Other than the search text, the search tool also takes your activity on the platform into account. This includes accounts you follow, posts you have viewed, with which accounts you interacted in the past, and how. This way, it is able to deliver exactly what you are looking for on the search results page.

How Instagram Keeps Search Safe

Mosseri also explained the ways through which the company keeps the search functionality remain safe for users. So, as per the Instagram head, the company restricts accounts that spam posts or violate the guidelines to show up at the top of the search results. For these kinds of accounts, users must put their full username on a search bar to find them on the platform.

Furthermore, the company balances the search results for sensitive topics with “additional safety measures” to ensure that no harmful content shows up on your search results page. Plus, the company entirely removes accounts, posts, and hashtags that violate the Community Guidelines, which prevents them from showing up as a search result.

How to Show up at the Top on Instagram Search

Now, other than explaining the technical details about Instagram’s Search function, Mosseri also provided some tips that will enable your account or posts to show up at the top of the search results page.

Other than this, you should use relevant hashtags, keywords, and locations in your Instagram profile bio as well as your posts to enable you to show up at the top of search results. These tips come from the head of Instagram, so you should include them in your profile to make you easily discoverable.

Future Plans for Instagram Search

So, these are some of the ways using which Instagram’s Search function works. Going forward, the company aims to introduce various new design improvements for search to better its performance and discoverability capabilities. The company says it is moving towards “a full search results page experience that makes it even easier to go deep on your interests.”

Moreover, Instagram will further improve the keyword search function of its search tool and add support for more languages other than English in the future.
