CREATE TABLE table_204_44 (id NUMBER, "face value" NUMBER, "\\u20ac0.01" NUMBER, "\\u20ac0.02" NUMBER, "\\u20ac0.05" NUMBER, "\\u20ac0.10" NUMBER, "\\u20ac0.20" NUMBER, "\\u20ac0.50" NUMBER, "\\u20ac1.00" NUMBER, "\\u20ac2.00" NUMBER)

what is the difference between the value of 0.01 in 2008 than that if 0.01 in 2002 ?
SELECT ABS((SELECT "\u20ac0.01" FROM table_204_44 WHERE "face value" = 2008) - (SELECT "\u20ac0.01" FROM table_204_44 WHERE "face value" = 2002))
SELECT ABS((SELECT "\u20ac0.01" FROM "table_204_44" WHERE "face value" = 2008) - (SELECT "\u20ac0.01" FROM "table_204_44" WHERE "face value" = 2002))
