SQL7.0 continuous loop

[Steve Tai <steve.tai () FRIJ COM AU>]

Hey People,

While mucking around with the vulnerabilities in SQL7.0, the code 

show xp_conv '\x90\x90\x90.........\x90\x90\x90'

with enough repetitions exists in the "\x90" the server displays the column ID's in a continuous loop restarting when 
it reaches 255
