CREATE TABLE table_204_187 (id DECIMAL, "type" TEXT, "power\ [w]" TEXT, "relative cost" DECIMAL, "input range\ [v]" TEXT, "energy storage" TEXT, "features" TEXT)

is the relative cost of the flyback above or below 1.5 ?
SELECT (SELECT "relative cost" FROM table_204_187 WHERE "type" = 'flyback') > 1.5
SELECT (SELECT "relative cost" FROM "table_204_187" WHERE "type" = 'flyback') > 1.5
