DISTINCT CLAUSE IN SQL

SELECT DISTINCT:

The SQL DISTINCT keyword is used in conjunction with SELECT statement to eliminate all the duplicate records and fetching only unique records.

There may be a situation when have multiple duplicate records in a table. While fetching such records, it makes more sense to fetch only unique records instead of fetching duplicate records.

SYNTAX:

SELECT DISTINCT column1, column2....columnN
FROM   table_name;

EXAMPLE:

SELECT   DISTINCT name from student;

Displays only  the values of the column name  without any duplicates present in the table.
