13.2 Inserting Data into Tables
Once we have created our database and table structure, there are a few ways we can populate the tables with data. One way is to manually insert data using the INSERT INTO statement. This can be a tedious process, especially if we have a large amount of data to insert. Another way is to import data from an external file, such as a CSV or Excel file.
This can save us time and effort, especially if we already have the data stored in a spreadsheet or other format. In addition, we can also use a scripting language or programming language to automate the data insertion process. This can be a powerful tool for managing large amounts of data or for automating routine tasks.
Overall, there are many different approaches we can take when it comes to populating our database tables with data, and the right approach will depend on our specific needs and circumstances.
Following our previous example, let's add some books to the 'Books' table:
INSERT INTO Books (BookID, Title, Author, Price)
VALUES
(1, 'To Kill a Mockingbird', 'Harper Lee', 7.99),
(2, '1984', 'George Orwell', 8.99),
(3, 'The Great Gatsby', 'F. Scott Fitzgerald', 6.99);The INSERT INTO statement is followed by the table name and a list of columns we wish to insert data into. The VALUES keyword is then used, followed by a list of values corresponding to the columns. Each set of parentheses after VALUES represents a single row of data. Here, we've inserted three rows (or records) into the 'Books' table.
