..
------------------

i run this sql (in mysql 4.1):

return a syntax error

how to implement it? (in mysql 4.1 and 4.0)

thanks :)

---

select *
from `keywordtable`
where  'aaabbbcccc' like CONCAT('%',`keyword`,'%')

---

select *
from `keywordtable`
where `keyword` like '%aaabbbcccc%'

the only problem is, that it searches case-insensitive, so AAAAAABBBCCCCCCCCDDD will also be matched

edit. i misread, you want to match the other way round. do this instead:

select *
from `keywordtable`
where 'aaabbbcccc' like '%'+`keyword`+'%'

mysql also understands like in reversed order
