database

I wanted to find out which domains were on somebody’s mailing list, and used this SQL command:

SELECT count((SUBSTRING_INDEX(SUBSTR(email, INSTR(email, ‘@’) + 1),’.’,1))), (SUBSTRING_INDEX(SUBSTR(email, INSTR(email, ‘@’) + 1),’.’,1)) FROM `phplist_user_user` group by (SUBSTRING_INDEX(SUBSTR(email, INSTR(email, ‘@’) + 1),’.’,1)) where confirmed=1 and blacklisted=0 order by count(SUBSTRING_INDEX(SUBSTR(email, INSTR(email, ‘@’) + 1),’.’,1)) desc

It resulted in this list. Pretty cool!
