SQL for Beginners

SQL is a language designed entirely for accessing databases and is the most popular of them.

Structured Query Language (SQL) is the standard language used to communicate with a relational database.

What are uses of SQL

SQL is used to access and manipulate a database.

SQL can:

  • insert, update, or delete records in a database.
  • create new databases, table, stored procedures, views.
  • retrieve data from a database, etc.

MySQL, MariaDB, Oracle are some of the programs that understand SQL.

Although most database systems use SQL, most of them also have their own additional proprietary extensions that are usually only used on their system.

However, the standard SQL commands can be used to accomplish almost everything that one needs to do with a database.

SQL is an ANSI (American National Standards Institute) standard, but there are different versions of the SQL language.
