 SQL - Wikipedia, the free encyclopedia
However, it also makes it possible for SQL source code to be produced (and optimized) by software, leading to the development of a number of natural language database query languages, as well as 'drag and drop' database programming packages with 'object oriented' interfaces.
Technically, SQL is a declarative computer language for use with "SQL databases".
SQL (commonly expanded to Structured Query Language — see History for the term's derivation) is the most popular computer language used to create, modify, retrieve and manipulate data from relational database management systems.

 What is SQL? - A Word Definition From the Webopedia Computer Dictionary
SQL is a standardized query language for requesting information from a database.
Increasingly, however, SQL is being supported by PC database systems because it supports distributed databases (databases that are spread out over several computer systems).
Historically, SQL has been the favorite query language for database management systems running on minicomputers and mainframes.

 SQL from FOLDOC
SQL was developed by IBM in the 1970s for use in System R.
The first SQL standard, in 1986, provided basic language constructs for defining and manipulating tables of data; a revision in 1989 added language extensions for referential integrity and generalised integrity constraints.
Development is currently underway to enhance SQL into a computationally complete language for the definition and management of persistent, complex objects.

 SQL Help and Tutorial
SQL is the language used to access the data and structures within a relational database.
I have tried to keep the SQL examples as generic as possible and much of this information applies to any SQL RDBMS but some of this information is for an Oracle environment.
Each RDBMS has an inbuilt query optimiser which parses your SQL statements and works out the optimum path to the required data.

SQL (Structured Query Language) is a computer language aimed to store, manipulate, and retrieve data stored in relational databases.
SQL Commands: How SQL statements are used to store, retrieve, and manipulate data in a relational database.
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.

 Oracle FAQ: SQL
Structured Query Language (SQL) is a language that provides an interface to relational database systems.
One way of working around this is to use PL/SQL, open the driving cursor with the "connect by prior" statement, and the select matching records from other tables on a row-by-row basis, inserting the results into a temporary table for later retrieval.
In common usage SQL also encompasses DML (Data Manipulation Language), for INSERTs, UPDATEs, DELETEs and DDL (Data Definition Language), used for creating and modifying tables and other database structures.

SQL or Structured Query Language is the universal language used for accessing data in relational database systems.
The authors recognize that SQL queries usually come about as a result of questions from human beings, and so usefully spend a fair bit of time showing how to convert questions into SQL.
The author explains administrative matters in SQL Server 2000, issues of database design, Structured Query Language (SQL), and integration of SQL Server databases into larger information systems.

 SQL Server Database Coding Conventions, Best Practices and Programming Guidelines
For example, if you create a table in SQL Server or a database that has a case-sensitive or binary sort order, all references to the table must use the same case that was specified in the CREATE TABLE statement.
Another major disadvantage of using dynamic SQL is that it requires users to have direct access permissions on all accessed objects, like tables and views.
In your applications, process all the results returned by SQL Server immediately so that the locks on the processed rows are released, hence no blocking.

 SecuriTeam™ - SQL Injection Walkthrough
A SQL Injection attack is a result of manipulating the standard SQL query language (used by nearly all DB products), and bad coding practices by the web developer.
With SQL Injection, it is possible for us to send crafted user name and/or password field that will change the SQL query and thus grant us something else.
Being able to inject SQL command usually mean, we can execute any SQL query at will.

 SQL Injection Attacks by Example
For simple queries this might be only a minor benefit, but as the operations become more complicated (or are used in more than one place), having a single definition for the operation means it's going to be more robust and easier to maintain.
Though quotesafing is a good mechanism, we're still in the area of "considering user input as SQL", and a much better approach exists: bound parameters, which are supported by essentially all database programming interfaces.
If we get a server error, it means our SQL is malformed and a syntax error was thrown: it's most likely due to a bad field name.
