SQL Fundamentals #2: SQL Data Manipulation

In our previous database exploration journey, SQL Fundamentals #1: SQL Data Definition, we set the stage by introducing the "books" table nestled within our bookstore database. Currently, our table is empty, Looking like :

books

| title | author | genre | publishedYear | price |

Data manipulation

Now, let's embark on database interaction—data manipulation. This is where the magic happens, where our "books" table comes to life, and we finish our mission of data storage.

Inserting Data

Our initial task revolves around adding a collection of books into our "books" table. we want to add the book "The Great Gatsby" to our collection, authored F. Scott Fitzgerald. Here's how we express this in SQL:

INSERT INTO books(title, author, genre, publishedYear, price) VALUES('The Great Gatsby', 'F. Scott Fitzgerald', 'Classic', 1925, 10.99);

Alternatively, you can use a shorter form for inserting values, but be cautious as it relies on the order of columns in your table:

INSERT INTO books VALUES('The Great Gatsby', 'F. Scott Fitzgerald', 'Classic', 1925, 10.99);

Updating data

As time goes on, you might find the need to modify existing data in our "books" table. To accomplish this, we use the UPDATE command.For example :

UPDATE books SET price = 12.99 WHERE title = 'The Great Gatsby';

This SQL statement will locate the row with the title "The Great Gatsby" and modify its price to $12.99.

We'll discuss the where clause in (SQL fundamentals #3)

Deleting data

Sometimes, data becomes obsolete or irrelevant, and it's essential to remove it from our table. The DELETE FROM command allows us to delete entire rows from our table.For example :

DELETE FROM books WHERE title = 'Moby-Dick';

This SQL statement will find the row with the title "Moby-Dick" and remove it entirely from your "books" table.

To maintain a reader-friendly and approachable tone, I'll save the discussion on the third part of SQL, which focuses on data querying, for the upcoming post. Stay tuned ...
