How to get spare no from categories 1 table where not exist per same spare no on table categories 2?

so i need to make select statement query select spare no from table categories 1 that have different categories
on table categories 2 per same spare no

as example spare no 1350 have category 5902 on table categories1 but on table categories2
i have same same spare no 1350 but have different categories as 7090 and 4020
then i select or display this spare no from table categories 1

as example spare no 1200 have category 5050 on table categories1 but on table categories2
i have same same spare no 1200 but have same categories as 5050 on table categories 2
so i don't need it or don't need to display it because it exist same sapre no and same category on table categories 2
