CREATE TABLE Tryout (pID NUMBER, cName VARCHAR2, pPos VARCHAR2, decision VARCHAR2)
CREATE TABLE Player (pID NUMBER, pName VARCHAR2, yCard VARCHAR2, HS NUMBER)
CREATE TABLE College (cName VARCHAR2, state VARCHAR2, enr NUMBER)

Show me a bar chart for what is minimum hours of the students playing in different position?
SELECT pPos, MIN(T2.HS) FROM Tryout AS T1 JOIN Player AS T2 ON T1.pID = T2.pID GROUP BY pPos
SELECT "pPos", MIN("T2"."HS") FROM "Tryout" "T1" JOIN "Player" "T2" ON "T1"."pID" = "T2"."pID" GROUP BY "pPos"
