SQL is short for Structured Query Language
and is a widely used database language,
providing means of data manipulation (store,
retrieve, update, delete) and database creation.
Almost all modern Relational Database Management
Systems like MS SQL Server, Microsoft Access, MSDE,
Oracle, DB2, Sybase, MySQL, Postgres and Informix use
SQL as standard database language. Now a word of warning
here, although all those RDBMS use SQL, they use different
SQL dialects. For example MS SQL Server specific version of
the SQL is called T-SQL, Oracle version of SQL is
called PL/SQL, MS Access version of SQL is called JET SQL, etc.
Our SQL tutorial will teach you how to use commonly
used SQL commands and you will be able to apply most
of the knowledge gathered from this SQL tutorial to
any of the databases above.
This SQL tutorial site lists commonly-used SQL statements, and it
covers the following sections:
1- SQL Data Manipulation
2- SQL Data Definition Language
In Structured Query Language we use syntax for executing queries. And the SQL
language also covers a syntax to Select, Update, Insert, and Delete
records in a database and these points of interacting with database is called
In Select section we will learn how to extract data from the database.
In Update we will learn how to update data stored in database.
in Insert section we will see how can we insert our own records in database.
And in Delete section we will learn how to remove an existing record from
DDL covers how to Create Delete and Alter a Table or an Index.
In this section we will also cover the RDBMS, (Relational Database Management
System). It means the relations of the database tables and indexes and impose
constraints between database tables.
For each command, the SQL syntax we will first be presented and explained,
followed by an example. At the end of this tutorial, you should have a good
general understanding of the SQL syntax, and be able to write SQL queries using
the correct syntax. Our experience is that understanding the basics of SQL is
much easier than mastering all the particulars of this database language, and We
are sure that you will reach the same conclusion as well. SQL is quite
easy to learn and you will really enjoy during learning with GGL.
