Have you ever wondered how to efficiently populate your database with initial data? Inserting data into a database script is a crucial task for developers and database administrators. This article will provide a detailed walkthrough on how to insert data into a database script, covering various aspects such as fundamental data, academic structures, resources, personnel, student information, and billing. Let's dive in!

Understanding the Basics of Database Scripting

Before we jump into the specifics, it’s important to understand the fundamentals of database scripting. A database script is essentially a set of SQL commands that automate database tasks, such as creating tables, defining relationships, and of course, inserting data. Using scripts ensures consistency and reproducibility, which is vital for managing databases effectively. The following sections will guide you through the process of inserting various types of data into your database script, ensuring a robust and well-populated database.

Essential Data Insertion: Laying the Foundation

Essential data forms the backbone of any database. This typically includes information about people, contact details, and locations. Let's examine how to insert this foundational data into your script. Consider the following SQL INSERT statements for the Persona, Telefono, and Sede_Universitaria tables:

-- Persona
INSERT INTO Persona (Ci, nombre, apellido, fecha_nac, direccion, correo) VALUES
(12345678, 'Juan', 'Perez', '1985-05-15', 'Av. Libertador, Edif. Apto 1A', 'juan.perez@email.com'),
(98765432, 'Maria', 'Gomez', '1992-10-20', 'Calle 5, Casa #25', 'maria.gomez@email.com'),
(45678901, 'Carlos', 'Lopez', '1970-03-01', 'Urb. El Bosque, Quinta M-12', 'carlos.lopez@email.com'),
(32109876, 'Ana', 'Rodriguez', '2000-01-25', 'Carrera 10, Apto 5B', 'ana.rodriguez@email.com'),
(23456789, 'Luis', 'Hernandez', '1995-11-30', 'Calle Principal, Local #3', 'luis.h@email.com'),
(77777777, 'Diego', 'Mendez', '1988-08-08', 'Calle 2, Qta. Sol', 'diego.m@email.com'),
(66666666, 'Elena', 'Silva', '1998-12-12', 'Av. Sur, Edif. PB', 'elena.s@email.com');

-- Telefono (FK: Persona)
INSERT INTO Telefono (id_telefono, CI_Persona, numero_telefono) VALUES
(1, 12345678, '0412-1234567'),
(2, 98765432, '0414-9876543'),
(3, 45678901, '0212-4567890'),
(4, 77777777, '0424-7777777'),
(5, 66666666, '0212-6666666');
