Creating Database(SQL)

Create a database if it does not exist!


-Stands for  Structured Query Language

Used to manage database //Update data on a database or retrieve data from a database

Start by creating your connection
Connect to MySQL
$link = mysql_connect($servername, $username, $password);
if (!link)
die('Could not connect ' . mysql_error());
Suppose we're creating a database with name 'test'. You must first of all make that db your current db.
$db_selected = mysql_select_db('test', $link);
You can now create your database with an appropriate name!
if (!db_selected)
$sql = 'CREATE DATABASE test';
if (mysql_query($sql, $link))
echo "Database test has been successfully made!";
require table.php;
echo "Error creating database: " . mysql_error() . "\n";

Note: You might be wondering why am I calling a table.php when the db is successfully created.
Well, this is not mandatory. I called the table.php because it will create a database table with given name.

Creating the database table

Suppose we are creating a database table with name test-table in our database.

This time while connecting to MySQL, you should insert your $dbname!
$conn = new mysqli($servername, $username, $password, $dbname); 

After connecting to MySQL, you can start creating your database table.
$sql = "CREATE TABLE test.test-table"
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
We've created our table name with:
1. id //declared as Integer and it will auto increment as well with length 6
2. firstname //declared as Varchar and length 30
3. lastname //decared asVarchar with length 30
4. email // declared as Varchar with length 50

Check if table has been created successfully!
if ($conn->query($sql) === TRUE)
echo "Table test_table created successfully";
echo "Error creating table: " . $conn->error;

How to install the FReMP Stack on Ubuntu 20.04?

Technology keeps on evolving everyday and developers constantly look for more and more things to get their hands-on. In this article, I will be introducing a new full stack framework, called FReMP . The abbreviation used is not the best one, but it just gets the work done in justifiable ways. What on earth is FReMP stack? The FReMP stack is a highly scalable full stack framework, which can be used to build awesome web apps. The acronym stands for F lask, Re actJS, M ongodb and P ython. Unlike other famous stacks such as MEAN and MERN, the FReMP stack uses Python to handle back-end operations. Examples of such operations can be machine learning and artificial intelligence operations, web scraping tools or digital image processing. Step 0: Update your list of installed packages While this is optional, it is always a good practice to update your list of packages and upgrade them for newer versions before starting any installation on your environment. Run the following to do so: $ apt-get

[Python]Publish your python project to PyPI

The Python Package Index, also known as PyPI, is a large repository of python packages. Millions of developers all around the world contribute to Python daily by creating python scripts and uploading to PyPI. In this blog post, I am going to write a simple python script that, on running, will print Hello World on the terminal. Then, going to upload this script to PyPI so that it can be installed on any platform easily using pip or pip3 . Requirements: 1. Github account 2. Basic knowledge of python 3. setuptools - (pip3 install setuptools) 4. wheel - (pip3 install wheel) By the end of this blog post, you should be able to print hello world using a single command: Let's get started! The first thing to do is find a unique name for your project. The name that I will call the Hello World script will be print_hello_world . At the time that I am writing this post, there is not package called print_hello_world  on  PyPI . Logically, after doing this tutorial, there might
