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

For each position, what is the minimum time students spent practicing Plot them as bar chart, I want to order in ascending by the bar.
SELECT pPos, MIN(T2.HS) FROM Tryout AS T1 JOIN Player AS T2 ON T1.pID = T2.pID GROUP BY pPos ORDER BY pPos
SELECT "pPos", MIN("T2"."HS") FROM "Tryout" AS "T1" JOIN "Player" AS "T2" ON "T1"."pID" = "T2"."pID" GROUP BY "pPos" ORDER BY "pPos" NULLS FIRST
