SQL is a standard language for accessing and manipulating databases.Although IT is an ANSI/ISO standard, there are different versions of this language. However, to be compliant with the ANSI standard, they all support at least the major commands in a similar manner.

RDBMS stands for Relational Database Management System.RDBMS is the basis for SQL. And for all modern database systems such as MS Server, IBM DB2, Oracle, MySQL, and Microsoft Access.

The data in RDBMS stored in database objects called tables. A table is a collection of related data entries, and it consists of columns and rows.
Most of the actions need to perform on a database done with the following statements.Some database systems require a semicolon at the end of each statement.

The semicolon is the standard way to separate each SQL statement in database systems that allow more than one SQL statement executed in the same call to the server.

The SELECT statement used to select data from a database. The data returned is stored in the result table, called the result-set.
