ng I might be missing something in regards to primary
keys...
Can a primary key (or unique key) be established on two columns (eg
primary key = client_id + post id)?
Can an auto-increment column only increment in relation to the client
id?
Or am I expecting *way* too much out of MySQL and rela
more complex query -- can any
one lend a hand?
My guess is maybe something like
SELECT article.title, article.user_id, user.username
FROM article, user
WHERE user.id = article.user_id

Can someone give me a quick/clear explanation about why you would
create a table with columns of NULL / NOT NULL?
I clicked around the MySQL manual last night I *think* I know what's
what, but it'd be great to read one clear paragraph that summarises it
all.

Hi all,
I'm currently logging page requests with the following table:
CREATE TABLE counters_hits (
pid tinyint(3) unsigned NOT NULL default '0',

) TYPE=MyISAM;
In other words, for ever page hit on my site, I'm recording the unix
timestamp & page ID.

Hi all,
On my LAN server (FreeBSD, MySQL 3.32) the following query works fine, and
seems to return 2 random rows from the table:
SELECT * FROM disc ORDER BY RAND() LIMIT 2
However, when I upload the scripts to the live server (Linux, MySQL 3.32),
the results are VERY un-random -- only very occas
sorry for the ambiguos subject, but not sure what terms to use!
I have four (relevant) tables:

service(sid,sname,cid)
sid2pid(sid,pid)
This works fine, listing all services available within a category:
SELECT service.sid,service.sname
FROM service
WHERE cid='3'
Hi,
I'm trying to dig a bit deeper into mysql queries... I've come across an
application that i'm building which requires (it would seem on the surface)
many queries, do to the relational nature of the data.
The actual app is way too complex to explain, but I've come up with a
reasonably simple e
ice_rel.sid
And I'm getting "Unknown table 'partners' in field list".
Any advice warmly received :)

Does MySQL "remember" anything itself? Does it have any back-up mechanisms?

I think the only filters on this list are that it must contain 'sql' or
'query'... The message starts with 'Attn: mysql', so I guess it got thru.

I'd rather strip out some noise words like 'a' & 'the' BEFORE using the
search term in a query, in order to maintain control.
Any ideas?

hi all,
given a certain id # (eg 4), how would i query the value either side of it
(usually 3 and 5). In theory, yes, it'd be 3 + 5, but in the case of the
following table:
1
4
5
it'd be 1 + 5, and this:
3
4
7
it'd be 3 + 7.
Even more interesting would be obtaining some sort of an error whe
more complex in the WHERE,
or am I way off track?
Any links to articles, FAQs, etc etc, or query snippets would be greatly
appreciated... I'm using MySQL in conjunction with PHP if that helps...
