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.
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
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.
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.
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.

b) DROP FROM CUSTOMER ...
c) Delete FROM CUSTOMER where...
d) update FROM
3. A View is which
of the following?
A virtual table
that can be accessed via SQL commands
b) A virtual table
that cannot be accessed via SQL commands
c) A base table that
can be accessed via SQL commands
d) A base table that
cannot be accessed via SQL commands
4. The command to
eliminate table from database is:
REMOVE TABLE CUSTOMER;
c) DELETE TABLE
d) UPDATE TABLE
convenience and flexibility are the major benefits that can be derived from
online SQL training. The choice of selecting the suitable day and time to
