SQL Tutorial
SQL -- pronounced sequel -- stands for Structured
Query Language. It is the language used to access data stored in a SQL
database. With SQL, you can query your database in a variety of ways, using
English-like statements.
With SQL, data is stored in tables. A table is a set of
columns and rows. Each column is referred to as a field. Each value in
a field represents a single type of data. For example, a table might have
three fields: name, city, and state. The table will consist of three columns:
one for name, one for city, and one for state. For every row in the
table, the name field contains the name, the city field contains the city,
and the state field contains the state. A database is a collection
of related data. It can also be viewed as a collection of related tables.
This tutorial is on storing data in and retieving data from a SQL
database.
