Congratulations — you've reached the end!
This SQL tutorial has provided you with a quick and easy way to learn SQL.
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
DISTINCT etc. These are all part of the DML (Data Manipulation Language).
Then, after covering the
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 etc), and there are commands for modifying (or altering) database objects (
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?
Check out my SQL Server tutorial to learn how to work with databases in SQL Server. Most tasks in SQL Server can be done via the GUI or with SQL scripts, so it's a great opportunity to try out your SQL knowledge.
I've also written a MySQL tutorial, which will be a great help if you're looking to create database driven websites. This tutorial uses MySQL Workbench which is a graphical tool for managing MySQL.
You might also be interested in some of the articles I've written over at Database.Guide. For example, I've written a whole SQL tutorial on one page. I've also written a joins tutorial and a transactions tutorial (which is one area we didn't cover in this tutorial).
Other valuable resources on that site include my SQL reference and my collection of basic SQL queries.
