CREATE TABLE table_203_56 (id NUMBER, "star" CLOB, "start\ year" NUMBER, "end\ year" NUMBER, "maximum\ year" NUMBER, "maximum\ magnitude" NUMBER, "distance at\ maximum  ( ly ) " NUMBER, "current\ distance" NUMBER, "current\ magnitude" NUMBER)

what is the difference in the nearest current distance and farthest current distance ?
SELECT MAX("current\ndistance") - MIN("current\ndistance") FROM table_203_56
SELECT MAX("current\ndistance") - MIN("current\ndistance") FROM "table_203_56"
