In tables some of the columns may contain duplicate values. But you want to list out the (distinct) values of a coloum in that table.
The DISTINCT keyword can be used to return only distinct (different) values.
First of all create a table.
create table dept_test( Deptno int,dname varchar(20),loc varchar(20))
Then insert records into the table you created .
insert into dept_test values(10,’it’,’haryana’)
insert into dept_test values(20,’hr’,’Delhi’)
insert into dept_test values(10,’admin’,’agra’)
insert into dept_test values(40,’canteen’,’Delhi’)
insert into dept_test values(60,’house keeping’,’Delhi’)
insert into dept_test values(70,’it’,’Delhi’)
insertinto dept_test values(30,’hr’,’kolkata’)
Then select records from your table.
Select * from dept_test
go
Select Distinct dname from dept_test
