3. Enter a name (e.g., MyDatabase) and click OK.

Example SQL Script:

CREATE DATABASE MyDatabase;
GO

Writing and Executing T-SQL Queries

Step 1: Create a Table

After setting up a database, create tables to store data.

Example Code:

USE MyDatabase;
GO
CREATE TABLE Employees (
    EmployeeID INT PRIMARY KEY,
    Name VARCHAR(100),
    Age INT,
    Department VARCHAR(50)
);

Step 2: Insert Data

Populate the table with sample data.

Example Code:

INSERT INTO Employees (EmployeeID, Name, Age, Department)
VALUES (1, 'John Doe', 30, 'IT'),
       (2, 'Jane Smith', 28, 'HR');

Step 3: Retrieve Data Using T-SQL

CREATE DATABASE BooksStore;
GO

Step 4: Create Tables Using T-SQL

Now that we have a database, let’s create a couple of tables. We’ll create a Books table and an Authors table for this example.

4.1 Create the Books Table

Run the following T-SQL script to create a table that will store book information:

USE BooksStore;
GO

-- Create Books Table
CREATE TABLE Books (
    BookID INT PRIMARY KEY IDENTITY(1,1),
    Title VARCHAR(255) NOT NULL,
    AuthorID INT,
    PublicationDate DATE,
    Price DECIMAL(10, 2)
);
GO

4.2 Create the Authors Table

Run the following T-SQL script to create a table for authors:

USE BooksStore;
GO

-- Create Authors Table
CREATE TABLE Authors (
    AuthorID INT PRIMARY KEY IDENTITY(1,1),
    Name VARCHAR(255) NOT NULL,
    DateOfBirth DATE
);
GO

Step 5: Insert Sample Data into Tables

Next, we’ll insert some sample data into both the Books and Authors tables.

5.1 Insert Data into Authors Table

-- Insert Sample Authors Data
INSERT INTO Authors (Name, DateOfBirth)
VALUES
('J.K. Rowling', '1965-07-31'),
('George Orwell', '1903-06-25'),
('J.R.R. Tolkien', '1892-01-03');
GO

5.2 Insert Data into Books Table

-- Insert Sample Books Data
INSERT INTO Books (Title, AuthorID, PublicationDate, Price)
VALUES
('Harry Potter and the Sorcerer\'s Stone', 1, '1997-06-26', 19.99),
('1984', 2, '1949-06-08', 15.99),
('The Hobbit', 3, '1937-09-21', 12.99);
GO

Step 6: Query Data Using T-SQL

Now that we have some sample data, let’s write a simple query to retrieve books along with their authors.

6.1 Join Tables and Retrieve Data

-- Retrieve Books and their Authors
SELECT 
    b.BookID, 
    b.Title, 
    a.Name AS Author, 
    b.PublicationDate, 
    b.Price
FROM 
    Books b
JOIN 
    Authors a ON b.AuthorID = a.AuthorID;
GO

Step 7: Perform Basic Data Manipulation with T-SQL

In T-SQL, you can perform various data manipulation operations, such as updating records, deleting records, and more.

7.1 Update a Record

Let’s update the price of “1984” to $17.99:

UPDATE Books
SET Price = 17.99
WHERE Title = '1984';
GO

7.2 Delete a Record

Let’s delete the book “The Hobbit” from the database:

DELETE FROM Books
WHERE Title = 'The Hobbit';
GO

Step 8: Set Up User Permissions

To manage who can access and modify the database, you can create users and assign permissions.

8.1 Create a New User and Grant Permissions

-- Create a New User
CREATE LOGIN dev_user WITH PASSWORD = 'StrongPass123';
CREATE USER dev_user FOR LOGIN dev_user;

-- Grant permissions to the user
GRANT SELECT, INSERT, UPDATE ON Books TO dev_user;
GO
