Day 1: Introduction to SQL and Relational Databases

Welcome to Day 1 of your SQL learning journey! 🚀

SQL (Structured Query Language) is the language of databases and is widely used for managing and analyzing data. Whether you're aiming for a career in Data Science, Data Analysis, Web Development, or Finance, SQL is an essential skill to master.

---

📌 What is SQL?
SQL stands for Structured Query Language and is used to communicate with databases. It helps you store, retrieve, manipulate, and manage data in a structured way.

Imagine a library database where details of books (title, author, genre, availability) are stored in tables. With SQL, you can:
✅ Find a book by its title
✅ Get a list of all books by a specific author
✅ Check how many books are available in a genre
✅ Add new books to the library collection
✅ Delete outdated records

---

📌 What is a Database?
A database is an organized collection of data that allows easy access, management, and updating.

There are two main types of databases:
1️⃣ Relational Databases (RDBMS): Data is stored in tables (like Excel). Examples: MySQL, PostgreSQL, SQL Server, SQLite.
2️⃣ Non-Relational Databases (NoSQL): Data is stored in key-value pairs, JSON, or documents. Examples: MongoDB, Firebase.

SQL works with Relational Databases (RDBMS).

---
📌 What is a Table?
A table is like a spreadsheet in Excel, with rows and columns.

📌 Example: A simple "Students" table

| Student_ID | Name | Age | Grade |
|------------|-------|-----|--------|
| 1 | Alex | 18 | A |
| 2 | Emma | 19 | B |
| 3 | John | 18 | A |

Each row represents a student, and each column stores a specific type of data (ID, Name, Age, Grade).

---

📌 SQL Commands Overview
SQL has different types of commands to manage data:

🔹 Data Query Language (DQL) – Used for fetching data
🔸 SELECT – Retrieve data from tables

🔹 Data Manipulation Language (DML) – Used for modifying data
🔸 INSERT – Add new data
🔸 UPDATE – Modify existing data
🔸 DELETE – Remove data

🔹 Data Definition Language (DDL) – Used for creating and modifying tables
🔸 CREATE TABLE – Create a new table
🔸 ALTER TABLE – Modify table structure
🔸 DROP TABLE – Delete a table

🔹 Data Control Language (DCL) – Used for user permissions
🔸 GRANT – Give permissions
🔸 REVOKE – Remove permissions

🔹 Transaction Control Language (TCL) – Used for managing transactions
🔸 COMMIT – Save changes permanently
🔸 ROLLBACK – Undo changes

---

📌 Setting Up a Database
To practice SQL, you need a database environment. You can use:

1️⃣ Online SQL Editors – No installation needed
- [SQL Fiddle](http://sqlfiddle.com/)
- [W3Schools SQL Editor](https://www.w3schools.com/sql/trysql.asp?filename=trysql_select_all)

2️⃣ Install a Database Software
- MySQL (Popular for beginners) – [Download](https://www.mysql.com/downloads/)
- PostgreSQL (Advanced features) – [Download](https://www.postgresql.org/download/)
- SQL Server (Used in enterprises) – [Download](https://www.microsoft.com/en-us/sql-server/sql-server-downloads)

- * → Means "all columns"
- FROM Students → Specifies the table name

---
🎯 Task for Today
1️⃣ Understand the basic SQL commands mentioned above.
2️⃣ Try an online SQL editor and execute SELECT * FROM Students;
3️⃣ Install MySQL or PostgreSQL (optional, but recommended).

---

📌 That’s it for Day 1! Tomorrow, we’ll learn about SQL Data Types and start writing basic queries. 🚀

💡 Like & comment if you're excited to continue this series! 😊❤️

Day 2: SQL Data Types and Writing Basic Queries

Welcome to Day 2 of your SQL learning journey! 🎉

Today, we’ll cover two important topics:
✅ Data Types in SQL – Understanding different types of data in a database
✅ Writing Basic SQL Queries – Learning how to retrieve data using SQL

By the end of this lesson, you’ll be able to create a table and write your first SQL query to fetch data! 🚀

---

📌 What Are Data Types in SQL?
A data type defines the kind of data a column can store. Each column in a table must have a specific data type to ensure that data is stored correctly.

For example, a "Name" column should store text, while an "Age" column should store numbers.

---

📌 Common SQL Data Types (MySQL, PostgreSQL, SQL Server)

1️⃣ Numeric Data Types (Used for storing numbers)
| Data Type | Description | Example |
|-----------|------------|---------|
| INT | Stores whole numbers | 25, 100, -50 |
| DECIMAL(p, s) | Stores decimal numbers with precision | 12.34, 99.99 |
| FLOAT / REAL | Stores floating-point numbers | 1.23, 3.14 |

🔹 Example: If you’re storing student ages, use INT. If you’re storing bank balances, use DECIMAL.

---

2️⃣ String (Text) Data Types
| Data Type | Description | Example |
|-----------|------------|---------|
| CHAR(n) | Fixed-length string (n characters) | 'A', 'USA' |
| VARCHAR(n) | Variable-length string (up to n characters) | 'John Doe', 'Hello World' |
| TEXT | Large text data | 'This is a long description...' |

🔹 Example: A column storing names should be VARCHAR(50), meaning it can hold up to 50 characters.

---

3️⃣ Date and Time Data Types
| Data Type | Description | Example |
|-----------|------------|---------|
| DATE | Stores only the date (YYYY-MM-DD) | '2025-02-02' |
| TIME | Stores only the time (HH:MM:SS) | '14:30:00' |
| DATETIME | Stores both date and time | '2025-02-02 14:30:00' |
| TIMESTAMP | Stores date & time (used for logging) | '2025-02-02 14:30:00' |

🔹 Example: If you’re storing a student’s birth date, use DATE. If you’re storing when a student logged in, use DATETIME.

---

📌 Creating a Table in SQL
Now that we understand data types, let’s create a table for our students.

CREATE TABLE Students (
    Student_ID INT PRIMARY KEY,
    Name VARCHAR(50),
    Age INT,
    Grade CHAR(1),
    Enrollment_Date DATE
);

🔹 Explanation:
- CREATE TABLE Students → Creates a table named Students
- Student_ID INT PRIMARY KEY → Unique ID for each student
- Name VARCHAR(50) → Stores student names (up to 50 characters)
- Age INT → Stores student ages
- Grade CHAR(1) → Stores single-character grades (A, B, C...)
- Enrollment_Date DATE → Stores the date of enrollment

---

📌 Writing Basic SQL Queries
Now, let’s insert some data and retrieve it using SQL queries.

1️⃣ Inserting Data into a Table

INSERT INTO Students (Student_ID, Name, Age, Grade, Enrollment_Date)
VALUES (1, 'John Doe', 18, 'A', '2023-09-01');

🔹 Explanation:
- INSERT INTO Students → Adds a new record to the Students table
- (Student_ID, Name, Age, Grade, Enrollment_Date) → Specifies the columns
- VALUES (1, 'John Doe', 18, 'A', '2023-09-01') → Provides the values

Now, let’s add a few more students:

INSERT INTO Students (Student_ID, Name, Age, Grade, Enrollment_Date) 
VALUES 
(2, 'Emma Smith', 19, 'B', '2022-08-15'),
(3, 'Alex Brown', 20, 'A', '2021-07-10'),
(4, 'Sophia Johnson', 18, 'C', '2023-01-20');

---

2️⃣ Retrieving Data Using `SELECT` Statement
To see all student records, use:

SELECT * FROM Students;

🔹 Explanation:
- SELECT * → Selects all columns
- FROM Students → Specifies the Students table

🔹 Output:
| Student_ID | Name | Age | Grade | Enrollment_Date |
|------------|--------------|-----|-------|----------------|
| 1 | John Doe | 18 | A | 2023-09-01 |
| 2 | Emma Smith | 19 | B | 2022-08-15 |
| 3 | Alex Brown | 20 | A | 2021-07-10 |
| 4 | Sophia Johnson| 18 | C | 2023-01-20 |

---

3️⃣ Retrieving Specific Columns
If you only want to see the Name and Age, run:

SELECT Name, Age FROM Students;

🔹 Output:
| Name | Age |
|--------------|----|
| John Doe | 18 |
| Emma Smith | 19 |
| Alex Brown | 20 |
| Sophia Johnson| 18 |

---

4️⃣ Filtering Data Using `WHERE` Clause
Find students who are 18 years old:

SELECT * FROM Students WHERE Age = 18;

🔹 Output:
| Student_ID | Name | Age | Grade | Enrollment_Date |
|------------|--------------|-----|-------|----------------|
| 1 | John Doe | 18 | A | 2023-09-01 |
| 4 | Sophia Johnson| 18 | C | 2023-01-20 |

---

5️⃣ Using Conditions (`AND`, `OR`)
Find students who are 18 years old and have Grade A:

SELECT * FROM Students WHERE Age = 18 AND Grade = 'A';

Find students who are either 18 or 19 years old:

SELECT * FROM Students WHERE Age = 18 OR Age = 19;

---

🎯 Task for Today
1️⃣ Understand SQL data types and their usage.
2️⃣ Create a Students table in an SQL editor.
3️⃣ Insert at least 5 records into your table.
4️⃣ Write `SELECT` queries to retrieve:
✅ All students

Day 3: Filtering Data Using the `WHERE` Clause and Logical Operators (`AND`, `OR`, `NOT`)

Welcome to Day 3 of your SQL journey! 🎉

Yesterday, we learned about SQL data types and basic queries using `SELECT`. Today, we will take it further and learn how to filter data using the WHERE clause and logical operators (AND, OR, NOT).

By the end of this lesson, you’ll be able to retrieve specific data based on conditions! 🚀

---

📌 What is the `WHERE` Clause?

In real-world databases, tables contain thousands or even millions of records. If you only want to find specific data, you need a filtering method.

The WHERE clause allows us to retrieve only the records that match certain conditions instead of displaying the entire table.

📖 Syntax:

SELECT column1, column2, ... 
FROM table_name 
WHERE condition;

---

📌 Using `WHERE` to Filter Data
Let’s take an example. We have a Students table with the following records:

| Student_ID | Name | Age | Grade | Enrollment_Date |
|------------|--------------|-----|-------|----------------|
| 1 | John Doe | 18 | A | 2023-09-01 |
| 2 | Emma Smith | 19 | B | 2022-08-15 |
| 3 | Alex Brown | 20 | A | 2021-07-10 |
| 4 | Sophia Johnson| 18 | C | 2023-01-20 |

---

1️⃣ Filtering Data with `WHERE` Clause

Example 1: Find all students who are 18 years old

SELECT * FROM Students WHERE Age = 18;

🔹 Output:
| Student_ID | Name | Age | Grade | Enrollment_Date |
|------------|--------------|-----|-------|----------------|
| 1 | John Doe | 18 | A | 2023-09-01 |
| 4 | Sophia Johnson| 18 | C | 2023-01-20 |

✅ Explanation:
- The query only selects students where Age = 18.

---

2️⃣ Using `AND` Operator

The `AND` operator allows us to filter based on multiple conditions.

Example 2: Find students who are 18 years old AND have Grade A

SELECT * FROM Students WHERE Age = 18 AND Grade = 'A';

🔹 Output:
| Student_ID | Name | Age | Grade | Enrollment_Date |
|------------|--------|-----|-------|----------------|
| 1 | John Doe | 18 | A | 2023-09-01 |

✅ Explanation:
- The query filters students who are both 18 years old AND have Grade A.

---

3️⃣ Using `OR` Operator

The `OR` operator allows us to filter if at least one condition is met.

Example 3: Find students who are either 18 OR 19 years old

SELECT * FROM Students WHERE Age = 18 OR Age = 19;

🔹 Output:
| Student_ID | Name | Age | Grade | Enrollment_Date |
|------------|--------------|-----|-------|----------------|
| 1 | John Doe | 18 | A | 2023-09-01 |
| 2 | Emma Smith | 19 | B | 2022-08-15 |
| 4 | Sophia Johnson| 18 | C | 2023-01-20 |

✅ Explanation:
- The query selects students who are either 18 OR 19 years old.

---

4️⃣ Using `NOT` Operator

The `NOT` operator helps us find records that do NOT match a certain condition.

Example 4: Find students who are NOT 18 years old

SELECT * FROM Students WHERE NOT Age = 18;

🔹 Output:
| Student_ID | Name | Age | Grade | Enrollment_Date |
|------------|-----------|-----|-------|----------------|
| 2 | Emma Smith | 19 | B | 2022-08-15 |
| 3 | Alex Brown | 20 | A | 2021-07-10 |

✅ Explanation:
- The query excludes students who are 18 years old.

---

📌 Combining `AND`, `OR`, and `NOT`

Example 5: Find students who are either Grade A OR Grade B, but NOT 18 years old

SELECT * FROM Students WHERE (Grade = 'A' OR Grade = 'B') AND NOT Age = 18;

🔹 Output:
| Student_ID | Name | Age | Grade | Enrollment_Date |
|------------|-----------|-----|-------|----------------|
| 2 | Emma Smith | 19 | B | 2022-08-15 |
| 3 | Alex Brown | 20 | A | 2021-07-10 |

✅ Explanation:
- The query selects students who have Grade A OR B.
- But it excludes students who are 18 years old.

---

📌 Using Comparison Operators with `WHERE`

| Operator | Meaning |
|----------|---------|
| = | Equals |
| != or <> | Not Equal |
| > | Greater than |
| < | Less than |
| >= | Greater than or equal to |
| <= | Less than or equal to |

Example 6: Find students older than 18 years

SELECT * FROM Students WHERE Age > 18;

🔹 Output:
| Student_ID | Name | Age | Grade | Enrollment_Date |
|------------|-----------|-----|-------|----------------|
| 2 | Emma Smith | 19 | B | 2022-08-15 |
| 3 | Alex Brown | 20 | A | 2021-07-10 |

✅ Explanation:
- The query selects students who are older than 18.

---

## 🎯 Task for Today
✅ Write a query to find students who are exactly 19 years old.
✅ Write a query to find students who are younger than 19.
✅ Write a query to find students who are either 18 OR 20 years old.
✅ Write a query to find students who are not Grade A.
✅ Write a query to find students who are older than 18 AND have Grade B.

---

🔍 Summary
✅ WHERE filters records based on a condition.
✅ AND requires both conditions to be met.
✅ OR requires at least one condition to be met.
✅ NOT excludes specific records.
✅ We can combine multiple conditions using AND, OR, and NOT.

---

📌 That’s it for Day 3! Tomorrow, we’ll learn about sorting data using `ORDER BY`, limiting results with `LIMIT`, and removing duplicates using `DISTINCT`. 🚀
