Initially created in the 1. SQL is regularly used by database administrators, as well as by developers writing data integration scripts and data analysts looking to set up and run analytical queries.

The uses of SQL include modifying database table and index structures adding, updating and deleting rows of data and retrieving subsets of information from within a database for transaction processing and analytics applications. Queries and other SQL operations take the form of commands written as statements commonly used SQL statements include select, add, insert, update, delete, create, alter and truncate. SQL became the de facto standard programming language for relational databases after they emerged in the late 1. Microsoft Certified Courses In Pakistan. Also known as SQL databases, relational systems comprise a set of tables containing data in rows and columns. Each column in a table corresponds to a category of data for example, customer name or address while each row contains a data value for the intersecting column. SQL standard and proprietary extensions. An official SQL standard was adopted by the American National Standards Institute ANSI in 1. International Organization for Standardization, known as ISO, in 1. More than a half dozen joint updates to the standard have been released by the two standards development bodies since then as of this writing, the most recent version is SQL 2. Both proprietary and open source relational database management systems built around SQL are available for use by organizations. They include Microsoft SQL Server, Oracle Database, IBM DB2, SAP HANA, SAP Adaptive Server, My. SQL now owned by Oracle and Postgre. SQL. However, many of these database products support SQL with proprietary extensions to the standard language for procedural programming and other functions. For example, Microsoft offers a set of extensions called Transact SQL T SQL, while Oracles extended version of the standard is PLSQL. As a result, the different variants of SQL offered by vendors arent fully compatible with one another. SQL commands and syntax. SQL commands are divided into several different types, among them data manipulation language DML and data definition language DDL statements, transaction controls and security measures. The DML vocabulary is used to retrieve and manipulate data, while DDL statements are for defining and modifying database structures. The transaction controls help manage transaction processing, ensuring that transactions are either completed or rolled back if errors or problems occur. The security statements are used to control database access as well as to create user roles and permissions. SQL syntax is the coding format used in writing statements. Figure 1 shows an example of a DDL statement written in Microsofts T SQL to modify a database table in SQL Server 2. Figure 1. An example of T SQL code in SQL Server 2. This is the code for the ALTER TABLE WITH ONLINE ON OFF option. SQL on Hadoop tools. SQL on Hadoop query engines are a newer offshoot of SQL that enable organizations with big data architectures built around Hadoop systems to take advantage of it instead of having to use more complex and less familiar languages in particular, the Map. Reduce programming environment for developing batch processing applications. More than a dozen SQL on Hadoop tools have become available through Hadoop distribution providers and other vendors many of them are open source software or commercial versions of such technologies. In addition, the Apache Spark processing engine, which is often used in conjunction with Hadoop, includes a Spark SQL module that similarly supports SQL based programming. In general, SQL on Hadoop is still an emerging technology, and most of the available tools dont support all of the functionality offered in relational implementations of SQL. But theyre becoming a regular component of Hadoop deployments as companies look to get developers and data analysts with SQL skills involved in programming big data applications.
