[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi!!
 
I found your email addresses in www.postgresql.org
 
I am working in a PHP search engine made with PHP and Postgres...
The database has one table called "findmaan" with the following info
 
   Column    |          Type          | Modifiers
-------------+------------------------+-----------
 url         | character varying(255) |
 title       | character varying(255) |
 keywords    | text                   |
 description | text                   |
 category    | integer                |
 rating      | integer                |
 cache       | text                   |
 
 
and there is another table called "categorias_findmaan"
 
   Column    |          Type          |                            Modifiers                           
-------------+------------------------+-----------------------------------------------------------------
 idx         | integer                | not null default nextval('"categorias_findmaan_idx_seq"'::text)
 descripcion | character varying(255) |
Unique keys: categorias_findmaan_idx_key
 
well.. what´s my problem? : I want to call the name of the category from the idx of the table "categorias_findmaan"...
for example, if I add one site in the table "findmaan" whose category is number "5", then the search engine would have to search in table "categorias_findmaan" and find, por example, that that number category is for "Culture web sites"...
 
So.. I can´t understant how do I have to do this...
 
and secondly... how do I add data to the table "categorias_findmaan" if the type is a integer?? I mean, how would I add the number 1=tennis web sites   or 2=educational web sites  etc...
 
I hope you can help me...
