Inactive Items last 2 years

Hi colleagues,

I am trying  to write a query to get all "Inactive Items" (no movements) in last 3 years? (I know there is a Report, but I need the query this time)

I've been thinking to use the OINV table but I don't know what 'Where' clause to return 'Inactive Items' only:

Select * from OINV

Thanks.
