CREATE TABLE table_60706 ("Position" FLOAT, "Club" CLOB, "Played" FLOAT, "Points" FLOAT, "Wins" FLOAT, "Draws" FLOAT, "Losses" FLOAT, "Goals for" FLOAT, "Goals against" FLOAT, "Goal Difference" FLOAT)

What is the lowest Goal Difference, when Position is '7', and when Played is greater than 30?
SELECT MIN("Goal Difference") FROM table_60706 WHERE "Position" = '7' AND "Played" > '30'
SELECT MIN("Goal Difference") FROM "table_60706" WHERE "Played" > '30' AND "Position" = '7'
