Example 1: Sequel in Ruby (Sequel-Ruby):

 # Connecting to a database

DB = Sequel.connect(“sqlite://my_database.db”)

# Creating a table

DB.create_table :users do

  primary_key :id

  String :name

  Integer :age

end

 # Inserting data into the table

users_dataset = DB[:users]

users_dataset.insert(name: ‘Alice’, age: 30)

users_dataset.insert(name: ‘Bob’, age: 25)

# Retrieving data from the table

alice = users_dataset.where(name: ‘Alice’).first

puts alice[:age]   # Output: 30

# Updating data in the table

users_dataset.where(name: ‘Bob’).update(age: 26)

# Deleting data from the table

users_dataset.where(name: ‘Alice’).delete

 In this example, we use Sequel-Ruby, which is a popular Sequel language for Ruby developers. We start by connecting to a SQLite database and then create a table named “users” with columns for “id,” “name,” and “age.” We insert two records into the table, retrieve data for “Alice,” update Bob’s age, and finally delete Alice’s record.

Example 2: Sequel in Python (Sequel-Python):

# Connecting to a database

import sequel

 DB = sequel.connect(“sqlite:///my_database.db”)

# Defining a model

class User(sequel.Model):

          name = sequel.CharField()

          age = sequel.IntegerField()

# Creating a table

User.create_table()

# Inserting data into the table

alice = User(name=’Alice’, age=30)

alice.save()

bob = User(name=’Bob’, age=25)

bob.save()

# Retrieving data from the table

alice = User.get(name=’Alice’)

print(alice.age)   # Output: 30

# Updating data in the table

bob.age = 26

bob.save()

# Deleting data from the table

alice.delete()

 This example demonstrates Sequel-Python, a popular Sequel language for Python developers. We define a model “User” and create a table based on that model. We then insert two records into the table, retrieve data for “Alice,” update Bob’s age, and delete Alice’s record using intuitive object-oriented syntax.

Example 3: Sequel in JavaScript (Sequel-JS):

// Connecting to a database

const sequel = require(‘sequel-js’);

const DB = sequel.connect(‘mongodb://localhost/my_database’);

// Creating a collection

const users = DB.collection(‘users’);

// Inserting data into the collection

users.insertOne({ name: ‘Alice’, age: 30 });

users.insertOne({ name: ‘Bob’, age: 25 });

// Retrieving data from the collection

users.findOne({ name: ‘Alice’ }).then (alice => {

  console.log(alice.age);   // Output: 30});

// Updating data in the collection

users.updateOne({ name: ‘Bob’ }, { $set: { age: 26 } });

// Deleting data from the collection

users.deleteOne({ name: ‘Alice’ });

 This example showcases Sequel-JS, a Sequel language for JavaScript developers. We connect to a MongoDB database, create a collection of “users,” and perform operations like inserting, retrieving, updating, and deleting data with straightforward syntax.

These concrete examples of popular Sequel programming languages demonstrate their effectiveness in simplifying database interactions. Sequel languages offer developers a seamless and user-friendly experience when working with data with their intuitive syntax, expressive commands, and object-oriented integration.
