DISTINCT=Different Values Suppose you have Employee Table:- E_Id LastName FirstName City 1 Patil Rajesh Pune 2 Kharad Datta Mumbai 3 Raut Amar Pune In a table, some of the columns may contain duplicate values. you will want to list only the different (distinct) values in a table then you have to use keyword DISTINCT in Select SQL statement. Distinct Syntax:- SELECT DISTINCT column_name(s) FROM table_name Example:- SELECT DISTINCT City FROM Employee Result:- City Pune Mumbai

Hi Arjun, Use DISTINCT keyword. The SELECT keyword allows us to grab all information from a column (or columns) on a table. This, of course, necessarily mean that there will be redundancies. What if we only want to select each DISTINCT element? This is easy to accomplish in SQL. All we need to do is to add DISTINCT after SELECT. The syntax is as follows: SELECT DISTINCT "column_name" FROM "table_name" For example, to select all distinct stores in Table Store_Information, Table Store_Information store_name Sales Date Los Angeles $1500 Jan-05-1999 San Diego $250 Jan-07-1999 Los Angeles $300 Jan-08-1999 Boston $700 Jan-08-1999 we key in, SELECT DISTINCT store_name FROM Store_Information Result: store_name Los Angeles San Diego Boston Thanks
