SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.

Introduction :
In SQL server, Identity column of a table is a column whose value increases automatically. The syntax is
IDENTITY [( seed, increment)]
The value in an identity column is created by the server and users are not allowed to insert a value into an identity column. Identity column can be used to uniquely identify the rows in the table. It is as good as primary key whose value is being determined by server automatically .
