CREATE TABLE table_204_495 (id NUMBER, "date" CLOB, "opponent" CLOB, "venue" CLOB, "result" CLOB, "attendance" NUMBER, "scorers" CLOB)

what is the difference in attendance between the first two entries ?
SELECT ABS((SELECT "attendance" FROM table_204_495 WHERE id = 1) - (SELECT "attendance" FROM table_204_495 WHERE id = 2))
SELECT ABS((SELECT "attendance" FROM "table_204_495" WHERE "id" = 1) - (SELECT "attendance" FROM "table_204_495" WHERE "id" = 2))
