CREATE TABLE college (cname CLOB, state CLOB, enr NUMBER)
CREATE TABLE tryout (pid NUMBER, cname CLOB, ppos CLOB, decision CLOB)
CREATE TABLE player (pid NUMBER, pname CLOB, ycard CLOB, hs NUMBER)

What are the different states that had students successfully try out?
SELECT DISTINCT T1.state FROM college AS T1 JOIN tryout AS T2 ON T1.cname = T2.cname WHERE T2.decision = 'yes'
SELECT DISTINCT "T1"."state" FROM "college" "T1" JOIN "tryout" "T2" ON "T1"."cname" = "T2"."cname" AND "T2"."decision" = 'yes'
