I keeping getting a syntax error in this SQL code. It's the first comma (after american') in the "where" statement. If I remove that comma and just leave it blank - the error then moves to the next comma (after 'asian') I don't understand. Any help is appreciated.

select race from hcan361_hw.dbo. cohort where race = 'black or african american's 'asian', 'hispanic', 'unknown', 'declined', 'native hawaiian or other pacfic islander
