Question

I’m having a problem with a MySQL query.
I need to display the following output:

id | name  |     leave_date
-------------
1    sam         2011-11-22
2    david       2011-11-23
3    cooper      2011-11-27
4    sam         2011-11-30

My query is

select * from table1 where leave_date != "2011-11-22" 

NOTE: YOU SHOULD NOT USE DIRECTLY THE “NAME”.. I NEED TO ELIMINATE THE REPETITION

I get output like this:

id | name  |     leave_date
-------------
2    david       2011-11-23
3    cooper      2011-11-27
4    sam         2011-11-30

But I want to eliminate “sam”, so output would be:

id | name  |     leave_date
-------------
2    david       2011-11-23
3    cooper      2011-11-27

Answer 1

select * from table1 where name not in
(select name from table1 group by name having count(*) > 1)
