CREATE TABLE table_203_145 (id DECIMAL, "position" DECIMAL, "club" TEXT, "played" DECIMAL, "points" TEXT, "wins" DECIMAL, "draws" DECIMAL, "losses" DECIMAL, "goals for" DECIMAL, "goals against" DECIMAL, "goal difference" DECIMAL)

did any clubs have no losses ?
SELECT (SELECT COUNT("club") FROM table_203_145 WHERE "losses" = 0) > 0
SELECT (SELECT COUNT("club") FROM "table_203_145" WHERE "losses" = 0) > 0
