I always love that feeling when you beat a problem that refuses to go away.
So do I - but I aint beaten it yet! :-(
I'm still getting '2' as being the number of posts in each category when '2' is
actually only the
number of posts in *one* of the categories...weird-huh?
Cheers.

Damn!!
That'll be it..
I'm running phpMyAdmin 2.1.0 , php.4.0.3pl1 and MySQL 3.22.32
Then again I don't get an error message from your query..???
Perhaps it has to do with the query being embedded, that is
*where* it's embedded:
$totalsql = SELECT category,COUNT(*) FROM $Tpostings GROUP
BY category;
$totalresult = mysql_query($totalsql,$connect) or
error(Sorry! I was unable to process the
required SQL transaction.);
while($totalrow = mysql_fetch_array($totalresult)) {
$total = $totalrow['category'];
}
//Results in:
'some stuff' being echoed to the page..
So I tried:
$totalsql = SELECT category,COUNT(*) AS total FROM
$Tpostings GROUP BY category;
//Resulted in '2' being echoed to the page (2 is the number
of posts in the 'some stuff' category)
but 2 is displayed as being the number of posts in *all* the
categories which isn't the case...
What do you think? (It's my luchtime too and I'm gonna go get some...)
Cheers once agin for trying.

Russ,
I recreated your table/data (it's lunchtime and I thought
I'd take a look at
this) - my query returned the rows as below:
--
category count (*)
Edit Delete russ category 3
Edit Delete some stuff 1
--
I'm running with phpMyAdmin 2.2.0rc3 on PHP Version
4.0.4pl1 (MySQL is
3.23.36) - perhaps the problem lies with the versions?

Damian:
Thanks for that but it doesn't do what I wanted though. It
actually returns the first item ('some
stuff') from the table, where I wanted the total number of
occurances of *each category* in the
table, thus indicating the number of posts for each category
in the 'posts' table.
!
Many thanks.

Russ,
This should work for you:
-
select category,count(*)
from posts
group by category;

All the best,

Hi there people:
I have a MySQL table consisting of category names among
other things.
I would like to be able to construct a query that tells me
the number of times a unique category
name occurs in the table:
//Table 'posts' from command-line
mysql explain posts;
+--+-+--+-+++
| Field| Type| Null | Key | Default|
Extra |
+--+-+--+-+++
| id | tinyint(3) | | PRI | 0 |
auto_increment |
| category | varchar(25) | | ||
|
| user | varchar(12) | | ||
|
| dateFrom | date| | | -00-00 |
|
| dateTo | date| | | -00-00 |
|
| title| varchar(25) | | ||
|
| body | text| | | NULL |
|
+--+-+--+-+++
7 rows in set (0.00 sec)
//Table 'posts' in phpMyAdmin tab
id category userdateFromdateTo title
body
