CREATE TABLE College (cName VARCHAR, state VARCHAR, enr DECIMAL)
CREATE TABLE Player (pID DECIMAL, pName VARCHAR, yCard VARCHAR, HS 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, and I want to display by the total number in descending please.
SELECT pPos, MIN(T2.HS) FROM Tryout AS T1 JOIN Player AS T2 ON T1.pID = T2.pID GROUP BY pPos ORDER BY MIN(T2.HS) DESC
SELECT "pPos", MIN("T2"."HS") FROM "Tryout" AS "T1" JOIN "Player" AS "T2" ON "T1"."pID" = "T2"."pID" GROUP BY "pPos" ORDER BY MIN("T2"."HS") DESC NULLS LAST
