For example, the output for all prime numbers  would be:

2&3&5&7


SELECT GROUP_CONCAT(NUMB SEPARATOR '&')
FROM (
    SELECT @num:[email protected]+1 as NUMB FROM
    information_schema.tables t1,
    information_schema.tables t2,
    (SELECT @num:=1) tmp
) tempNum
WHERE NUMB<=1000 AND NOT EXISTS(
		SELECT * FROM (
			SELECT @nu:[email protected]+1 as NUMA FROM
			    information_schema.tables t1,
			    information_schema.tables t2,
			    (SELECT @nu:=1) tmp1
			    LIMIT 1000
