Thank you. Then could you please show me the players from Iraq? | Do you want their names? | yes, the 'player' field, so names.
SELECT T1.player FROM match_season as T1 join country as T2 on T1.country  =  T2.country_id where T2.country_name  =   "Iraq"
players from Iraq refers to filtering records based on country_name = 'Iraq'; 'player' field so names refers to selecting the column named 'player' from the table; joining tables on country_id to match countries.
