This SQL tutorial has provided you with a quick and easy way to
learn SQL and here we make it easiest and hope you have really enjoyed.
We began by learning that SQL stands for Structured Query Language, and
is an ANSI standard. We then learned the basic SQL syntax, before continuing
on to the SELECT statement - probably the most commonly used statement.
We learned that there are various keywords and aggregate functions
that can be included into SQL statements such as WHERE, COUNT,
DISTINCT etc. These are all part of the DML (Data Manipulation Language).
Then, after covering the INSERT, UPDATE, and DELETE statements,
we learned that there are various commands for performing administration
tasks against a database. For example, there are commands for creating
database objects (CREATE TABLE, CREATE INDEX, CRATE VIEW etc), and there are
commands for modifying (or altering) database objects (ALTER INDEX,
ALTER TABLE etc). These commands are part of the DDL (Data Definition Language).
Where to Next?
If you're keen to get into SQL programming, you should download a
database management system (if you haven't already) and practice SQL
statements against it. You should also read your database system's
documentation for any proprietary commands, functions or features.
For example, does your database system have an automatic scheduler?
Are you able to link your database server to a database on another
server? How do you perform backups on your database system?
And lastly, if you're new to web
development, check out one of the
other tutorials on Quack it - for
example, the
