Hi, I have a query which looks like this...
SELECT
BLEAH,
COUNT(DISTINCT R1,R2)
FROM
T1
WHERE
FK = 1
GROUP BY
BLEAH
;
Lets say that over 10 rows where FK = 1 it counts 5 distinct R1-R2 pairs
in a single 'BLEAH' group BLEAH = 'Y'.
Now I want to search the table for all FK's
BY titel
Earlier, before I added the max(datum) to the query, i could get the
number of rows by doing:
--- SQL ---
SELECT count( DISTINCT film_film.filmid, titel,
IF (
aar IS NULL , '', aar
),
IF (
termin IS NULL , '', termin
) ) AS antal
FROM (
(
(
`film_film`
LEFT JOIN
HELP! I'm getting the following error:
--
Error (SQL):
SELECT date, subject, location, private, id, duration, dategroup_id,
COUNT(DISTINCT subject) AS appointment_count, inituserid FROM mgw_calendar
WHERE userid=1 AND SUBSTRING(date,1,8) = '20030312' GROUP BY date, subject,
location

I'm stuck right now with using v. 3.22.32. Yes, I know I need to
upgrade, but I can't for various reasons. Anyway, I need to do a select
count(distinct column) from table query, but can't since this version
doesn't support it. How can I do this?
Thanks,
Brian
by using an alias for the
expression:
mysql SELECT id,FLOOR(value/100) AS val FROM tbl_name
GROUP BY id,val ORDER BY val;

Hi,
can it be that there is a bug in count(distinct(putafieldnamehere)) ?
After restarting the server it runs, but after some time it doesnt return
any result-rows.
A count(putafieldnamehere) runs without problems in this situation.
Thanx for any sugesstions to solve this problem ...

Ok, its not in count(distinct()). It always happends if temptables are used,
but only if the server
runs some minutes/hours/days :(

I am inclined to think (actually guess) it may be the version of MySQL you
are using. I am using MySQL 3.23.39 and I am able to successfully execute:
select count(distinct field) or select count(distinct(field))
I tried to make a quick check of the docs to see if a certain version

What's your MySQL version? Check the docs to see what version is
required for count(distinct). I think it was added in 3.23.early,
so it might be time to upgrade.

Hi,
we're trying to recommend that clients upgrade to version 3.23.36, and
wanted to ensure that it's stable. Particularly, have there been any bugs
regarding any bugs regarding the use of COUNT(DISTINCT since then?
In other words, if our software performs a COUNT(DISTINCT column) FROM

I can make this query: select a from table.
I can count it: select count(a) from table.
I can select it: select distinct a from table.
But how can i count it?
select count(distinct a) from table doesn't works

Hi there,
Doesn't seem to be a FAQ so here goes with a question
My MySQL manual has the following to say about how to count the number
of distinct values in a particular column
COUNT(DISTINCT expr,[expr...])
Returns a count of the number of different values.
mysql select COUNT(DISTINCT results
You can use:
SELECT Column_Name, count(Column_Name) FROM Table_Name GROUP BY
Column_Name
