So far, to create a query we have learned to use either the Query Wizard or the Design View of a query. In both cases, we were selecting fields and adding them to the query. This concept of building a query is based on the Structured Query Language abbreviated SQL. In fact, all queries are based on SQL and this language is used by most database development environments, including Microsoft Access.

The Structured Query Language (SQL) is the most popular language used in computers to create and manage databases. SQL is a language with its own syntax and grammar. SQL is a universal language that doesn't belong to a particular company. This makes it easy for different companies or programming environments to adopt it. In this site, we will study techniques of creating databases and we will use the SQL.

Introduction Structured Query Language

Preview
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.

Learn Database SQL Technology

Preview
Structured Query Language (SQL) is a language that was developed by IBM for processing data in mainframe databases. The relational nature of databases and the ease of SQL usage has made SQL the standard language for databases. SQL technology is also standardized which makes it ideal for usage across multiple fields. Learning SQL database technology will enable you to program and maintain any database with ease.
 

SQL Queries

Preview
You need to become familiar with SQL (Structured Query Language) because you will need it if you ever develop a Microsoft Access application and have to issue queries through code. You also need SQL to query other database systems, such as Oracle and MySql. Finally, once you know SQL, it is often easier to write a query directly in SQL than to design it using Access's QBE interface.

Access SQL: basic concepts, vocabulary, and syntax

Preview
When you want to retrieve data from a database, you ask for the data by using Structured Query Language, or SQL. SQL is a computer language that closely resembles English, but that database programs understand. Every query that you run uses SQL behind the scenes.
Understanding how SQL works can help you create better queries, and can make it easier for you to understand how to fix a query that is not returning the results that you want.
This is one of a set of articles about Access SQL. This article describes the basic use of SQL to select data, and uses examples to illustrate SQL syntax.
In this article
* What is SQL?
* Basic SQL clauses: SELECT, FROM, and WHERE
* Sorting the results: ORDER BY
* Working with summarized data: GROUP BY and HAVING
* Combining query results: UNION
