The Structured Query Language (SQL)

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.

Introduction to SQL
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.


Create a SQL Query
SQL queries use Structured Query Language (SQL), a standard scripting language, to make requests from databases. You can use four types of SQL queries in Access 97: union, pass-through, data-definition and subquery.


Introduction to SQL (Structured Query Language) (VB6)
This tutorial explains in great depth how the SQL language works. It has many examples and uses access databases to demonstrate the SQL syntax.


Introduction 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.

Basic queries using SQL
Query-By-Example (QBE) and Structured Query Language (SQL) are both well-known, industry standard languages for extracting information from relational database systems. The advantage of QBE that it is graphical and relatively easy to use. The advantage of SQL is that it has achieved nearly universal adoption within the relational database world. Learning objectives: understand the difference between QBE and SQL; create an SQL query; use SQL as a data definition language. (pdf file install Acrobat Reader to read this tutorial)


Learn Database SQL Technology
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
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
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


DELETE and UPDATE Data using SQL
In continuation of our exploration of the DML (Data Manipulation Language) components of SQL (Structured Query Language), here we introduce two more fundamental commands - SQL DELETE and SQL UPDATE.
These two commands are used to edit the contents of the database, and do not alter the underlying structure of the database.

How to Write SQL Statements
You don’t have to use the Select Query window in Microsoft Access to extract information from your database. Using Structured Query Language (SQL) is often quicker and easier. Here are the basics.


RDBMS Basics
Basically RDBMS (Relational Database Management System) is nothing but a standard. For many years database industry was not having any standard for storing and retrieving information. As a result to this standard we came up the language called SQL or Structured Query Language. We use SQL to communicate with RDBMS databases including but not limited to MS Access, Oracle, MS SQL Server etc. MS Access database have file extension as .mdb.


INSERTing Data using SQL
The Data Manipulation Language aspect of SQL (Structured Query Language) refers to the commands and functions of the language designed to modify the data in the database. The database structures remain unchanged, while the data held within is updated, deleted or inserted. The selection of data, via a query, is also part of the DML architecture.
SQL INSERT, UPDATE and DELETE are the Updating commands of the DML, while SELECT is the general Querying command. The INSERT statement will be dealt with here, but we will in future articles in this series explore the usage of UPDATE, DELETE and the wide-ranging SELECT command.


Microsoft Access SQL Tutorials
Here you will find articles relating to SQL (Structured Query Language) and SQL use and implementation in Microsoft Access. You will find articles and topics relating to SQL query designs, from planning what tables and fields will be used to selecting criteria to be used in the SQL Statements. There are articles on SQL basics, SQL Select, Insert, Update and Delete Statements and topics on why use SQL.


What is SQL?
Structured Query Language (SQL) is both the International Organization for Standardization (ISO) and the American National Standards Institute (ANSI) standard language for creating, updating and querying relational database management systems (RDBMS). Both ISO and ANSI are influential in establishing standards for technology and computing. The standardization of SQL, at both the international and national levels, ensures compatibility and consistency in database development around the world. ...


Use the Access 2007 Query Wizard
The Access 2007 query wizard allows you to create queries without using Structured Query Language (SQL), the language normally used to retrieve data from a database. You may specify fields from more than one data source and the query wizard also is able to calculate averages, counts, maximums, minimums and sums. The following steps will show how to use the Access 2007 query wizard.
