Nearly all individuals working in the role of a programmer or developer should acquire skills in many different kinds of programming languages. Amongst them is Structured Query Language or SQL which has turned out to be a virtually widespread means of data access and manipulation in databases. For a better learning experience and a rewarding career thereafter, an aspirant can go for online SQL training from a well-known institution.

The origin of SQL can be dated back to 1974 when Donald D. Chamberlin and Raymond F. Boyce at IBM originally developed it in the name of Structured English Query Language (SEQUEL). However, the short form SEQUEL was afterwards changed to SQL due to a trademark violation. IBM and Oracle were actually the foremost companies to develop this technology. This specifically designed programming language usually handles data in a relational database management system (RDBMS). Various scopes of the language consist of inserting, updating and deleting data, querying, creating and modifying schema, and controlling access to data.

The mounting popularity of SQL has created numerous job opportunities ...
... as an SQL programmer these days. It is a huge market that is flooded with openings that have attractive pay packages. Opting for training seems logical if you wish to build a career in this field, regardless of whether you're a novice or already possess some sort of knowledge of the language. There are bricks and mortar schools as well as web-based institutions that provide high quality SQL training to aspirants.

With the dominating impact of the Internet on our lives nowadays, some institutes have come up with a wide range of software courses and training online. In case you don’t have time to incorporate another campus-based program into your already hectic schedule, online training can deliver you the desired flexibility to learn or upgrade your SQL skills.

A typical Oracle-based SQL training over the internet comprises classes on introduction to database, types of databases, tools used in database, introduction to Structured Query Language, selecting queries, sorting data, restricting data, aggregate functions, grouping data, table creation, table joins, indexes, views and set operators. After completing all these classes, students can test their knowledge by attempting hundreds of quizzes posted on the website. All these quizzes are time-bound and graded by the instructors. Take a look at some of the examples below:

1. You can add a row using SQL in a database with which of the following?
