A company wants to store their invoices in a database. They
already have their customers and articles in that database.
Both customer and article are each identified by an unique
integer value. Please create the SQL statements for
creating the necessary table(s) for storing the invoices in
a MySQL database. An invoice should hold information like
invoice number, customer, date, article(s) and quantity
etc.
Answer / frank
Assume existing tables for customer and article are:
customers
+------------+----------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra
|
+------------+----------+------+-----+---------+----------------+
| customerId | int(11) | NO | PRI | NULL |
auto_increment |
| customer | char(50) | NO | | NULL |
|
+------------+----------+------+-----+---------+----------------+
article:
+-----------+----------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------+----------+------+-----+---------+----------------+
| articleId | int(11) | NO | PRI | NULL | auto_increment |
| article | char(50) | NO | | NULL | |
+-----------+----------+------+-----+---------+----------------+
CREATE TABLE invoices (invoiceId INT AUTO_INCREMENT PRIMARY
KEY,customerId INT NOT NULL,articleId INT NOT
NULL,invoiceNumber CHAR(20) NOT NULL UNIQUE,invoiceDate DATE
NOT NULL,quantity INT NOT
NULL,INDEX(customerId),INDEX(articleId));
