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.
