una quert mysql

Scusatemi ma le pagine di visualizzazione dei dati dal mio database mysql
funziona bene tranne quando voglio selezionare meglio i dati della query per
visualizzare solo i records che risposndano ad una determinato filtro
Per esempio io voglio impostare il filtro sul campo "TIPO" e selezionare
solo quei records che contengono la fease "di feltro a righe rosse"
Se faccio
$query = "SELECT nome, colore, memo FROM archivio where tipo='di feltro a
righe rosse'";
non mi seleziona i records il cui campoo tipo contiene "di feltro a righe
rosse" ma solo quelli che contengono la ferase esatta "di feltro a righe
rosse" e non contenuta in una frase più lunga Siccome la frase "di feltro a
righe rosse" potrebbe essere contenuta anche in un campo memo fra centinaia
e centinaia di caratteri

Come devco fare per favore?
Grazie

There are two languages we use here, english and php. Go to
it.comp.www.php if you want to speak italy.

Hi
I am sorry but my english is very bad
I must make a mysql_query selecting some records from a table
My selectiom must select only records that contain a certain phrase stored
into a fierld memo that can be very long
How can I weite because mysql understand that I want to search the phrase
stored into the lonh char fields:
select * from my table where my_field_memo contain "phrase contained into"

Undertstand now?

Regards

The answer is both simple and tremendously expensive:

select *
from my table
where my_field_memo like '%phrase contained into%'

If you are searching TEXT fields, MySQL supports full-text indexing
and searching.
