Return a row from query where keys are different from other rows in the same table

Hello guys

I have a table with some rows, I need to make a query where only the row that is diferent from must be return in my query

something like this the x.codprod='A1258'


select * from table01 a
inner join table01 b on (b.xname<>a.xname and b.xcoddep<>a.xcoddep and b.xcodprod<>a.xcodprod)

it should return me

create table table01 (
xname varchar(20),
xcoddep varchar(20),
xcodprod varchar(20)
)

insert into table01 (xname, xcoddep, xcodprod) values ('alexandre', '01452', 'A1257')
insert into table01 (xname, xcoddep, xcodprod) values ('alexandre', '01452', 'A1257')
insert into table01 (xname, xcoddep, xcodprod) values ('alexandre', '01452', 'A1257')
insert into table01 (xname, xcoddep, xcodprod) values ('alexandre', '01451', 'A1258')

select * from table01

Select allOpen in new window
