Structured Query language Tutorials


  1. SamsTeach Yourself SQL
    Welcome to the world of relational databases and SQL! This book is written for those self-motivated individuals out there who would like to get an edge on relational database technology by learning the Structured Query LanguageSQL. This book was written primarily for those with very little or no experience with relational database management systems using SQL. This book also applies to those who have some experience with relational databases but need to learn how to navigate within the database, issue queries against the database, build database structures, manipulate data in the database, and more. This book is not geared toward individuals with significant relational database experience who have been using SQL on a regular basis.
  2. SQL Tutorial - Learn SQL
    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.
  3. Introduction to Structured Query Language
    This page is a tutorial of the Structured Query Language (also known as SQL) and is a pioneering effort on the World Wide Web, as this is the first comprehensive SQL tutorial available on the Internet. SQL allows users to access data in relational database management systems, such as Oracle, Sybase, Informix, Microsoft SQL Server, Access, and others, by allowing users to describe the data the user wishes to see. SQL also allows users to define the data in a database, and manipulate that data. This page will describe how to use SQL, and give examples. The SQL used in this document is "ANSI", or standard SQL, and no SQL features of specific database management systems will be discussed until the "Nonstandard SQL" section. It is recommended that you print this page, so that you can easily refer back to previous examples. 
  4. SQL - Structured Query Language
    The objective of this chapter is to introduce the main concepts of data storage and retrieval in the context of database information systems. 
    In view of their prominence this booklet concentrates on the general characteristics of Relational Database Management Systems (RDBMS) and the Structured Query Language SQL and does not consider any of the numerous other types of databases. No prior knowledge of SQL is assumed.  It is intended that the SQL presented in this booklet be followed interactively and that the you should try all the given examples in the order in which they are presented. At the end of the booklet you should have attained a thorough knowledge of SQL and its capabilities as an interactive statement language.
  5. The SQL Course
    This unique introductory SQL tutorial not only provides easy-to-understand SQL instructions, but it allows you to practice what you learn using the on-line SQL interpreter. You will receive immediate results after submitting your SQL commands. You will be able to create your own unique tables as well as perform selects, inserts, updates, deletes, and drops on your tables. This SQL tutorial currently supports a subset of ANSI SQL. The basics of each SQL command will be covered in this introductory tutorial. Unless otherwise stated, the interpreter will support everything covered in this course. If you're already familar with the basics of SQL, you can still use this as a refresher, and practice some SQL statements.
  6. The W3Schools
    SQL is a standard computer language for accessing and manipulating databases. In this tutorial you will learn how to use SQL to access and manipulate data in Oracle, Sybase, SQL Server, DB2, Access, and other database systems.SQL is an ANSI (American National Standards Institute) standard computer language for accessing and manipulating database systems. SQL statements are used to retrieve and update data in a database. SQL works with database programs like MS Access, DB2, Informix, MS SQL Server, Oracle, Sybase, etc.Unfortunately, there are many different versions of the SQL language, but to be in compliance with the ANSI standard, they must support the same major keywords in a similar manner (such as SELECT, UPDATE, DELETE, INSERT, WHERE, and others).
  7. The SQL Tutorial
    SQL (Structured Query Language) is a computer language aimed to store, manipulate, and retrieve data stored in relational databases. The first incarnation of SQL appeared in 1974, when a group in IBM developed the first prototype of a relational database. The first commercial relational database was released by Relational Software (later becoming Oracle).  Standards for SQL exist. However, the SQL that can be used on each one of the major RDBMS today is in different flavors. This is due to two reasons: 1) the SQL standard is fairly complex, and it is not practical to implement the entire standard, and 2) each database vendor needs a way to differentiate its product from others. In this tutorial, such differences are noted where appropriate. 
  8. The SQL Course2
    Welcome to! This unique SQL Tutorial is the "sequel" to the highly successful site and will provide you with more advanced easy-to-follow SQL Instruction and the ability to practice what you learn on-line with immediate feedback! You will receive immediate results on a web page after submitting your SQL Commands.This continuation course will provide you with critical need-to-know advanced features and clauses of the SELECT statement that weren't supported in the previous site. Everything you learn here will be ANSI SQL compliant and should work with most SQL databases such as Oracle, SQL Server, mySQL, MS Access, Informix, Sybase, or any other ANSI SQL compliant database. 
  9. The SQL Syntax
    This document is written for users who wish to run their own queries of the database. Before beginning your first "customized" query you would be wise to familiarize yourself with the TABLE and fieldnames and definitions - these will figure prominently in your query.  The DMC stores terabytes of data from networks and stations around the globe. Users wanting to request this data must first inform themselves of what networks and stations send their data to the DMC for archiving. Once this information is obtained it is in the users best interest to make sure, for example, that data is indeed available for a given time period or station channel BEFORE their request is submitted so as to avoid the "no data" message from the DMC.
  10. How to retrieve data with the SQL SELECT statement
    Since 1974, our books have been used by hundreds of colleges, community colleges, and vocational educational programs; by dozens of Fortune 500 companies for in-house training programs; and by more than 200,000 programming professionals for self-instruction. 
    To facilitate classroom instruction, we provide Instructor?s Guides for our. If you're a trainer or instructor who would like to use this book for a course, we've developed a complete package of student and instructor's materials. These include a Student Workbook, an Instructor's CD, and Java tutorials that expand upon the content in the book.
