In a table, some of the columns may contain duplicate values. This is not a problem, however, sometimes you will want to list only the different (distinct) values in a table.
The DISTINCT keyword can be used to return only distinct (different) values.
The created Table is : 
Create a Database named "Studysql" and a table named "tbl_biodata"
Right click on the database Studysql and select new query.Then we can write queries as per the requirements.

Here, refer the field CITY . The column COCHIN is repeated 2 times.
Now we want to select only the distinct values from the column named "City" from the table above.
To do so, write the command like this in SQL.
| 
SELECT DISTINCT City FROM
  tbl_biodata | 
The result-set will look like this:
SQL SELECT Syntax of the same is :
SELECT DISTINCT column_name(s)
FROM table_name
FROM table_name
