CREATE TABLE table_204_17 (id DECIMAL, "region" TEXT, "date" TEXT, "format" TEXT, "version ( s ) " TEXT, "label" TEXT)

did the cd single come out before the digital ep ?
SELECT (SELECT "date" FROM table_204_17 WHERE "format" = 'cd single') < (SELECT "date" FROM table_204_17 WHERE "format" = 'digital ep')
SELECT (SELECT "date" FROM "table_204_17" WHERE "format" = 'cd single') < (SELECT "date" FROM "table_204_17" WHERE "format" = 'digital ep')
