SELECT company_name FROM table WHERE user_id='wordpress'
You should consider learning basic SQL if you plan on doing this in the future.
If you want distinct results, use:
SELECT distinct company_name FROM table WHERE user_id='wordpress'

I want to create an query to have the all matchs that a player win.
So, I have this table
ID_PLAYER1 ID_PLAYER2 SCORE_PLAYER1 SCORE_PLAYER2
1 4 5 3
2 1 3 4
3 4 2 0
I want to have this :
ID_PLAYER MATCH_WIN
1 2
2 0
3 1
4 0
Thank you !
I'm answering this because it's non-trivial and because I want to see if I can actually do it :p
SELECT `ID_PLAYER`, COUNT(*) AS `MATCH_WIN` FROM
(SELECT
IF(`SCORE_PLAYER1`>`SCORE_PLAYER2`, `ID_PLAYER1`, `ID_PLAYER2`) AS `ID_PLAYER`
FROM `your_table_name_here`
) AS `tmp`
GROUP BY `ID_PLAYER`

I have the database as follows
Name | Area 1 | Area 2
XYZ 200 300
ZUX 0 0
YYZ 100 200
What I want to do is, count the number of rows where SUM of (Area 1 and Area 2) is not equal to 0. In the example mentioned, It's 2. (SUM has to be calculated virtually)
I tried to use different ways with Find(); Still no luck.
Try this:
<?php
$this->Model->find('count', array(
'conditions' => array(
'(Area1 + Area2) != ' => 0
)
));
// returns 2
?>

That's because COUNT returns only one row, always. But in that row you'll find field with all rows counted, in one integer.
Try to fetch that row.
And next thing you should do is checking PDO extension. It's better than deprecated mysql_* functions and isn't so hard to learn.

I have two MySQL tables with the following...
Apps
ID | Name
1 App1
2 App2
and...
Minutes
ID | AppID | Amount
1 1 10
2 1 15
3 2 35
I want to pull the Apps and display them by time used. Should look like this...
App2 35 minutes
App1 25 minutes
How can I do this?
Thank you.
You can use a JOIN with a GROUP BY. To add the amounts together use the SUM aggregate funcion.
SELECT name, SUM(amount)
FROM `apps`
JOIN minutes ON `apps`.`id` = `minutes`.`appid`
GROUP BY `apps`.`id`
Use a JOIN (SQL):
SELECT
Apps.Name,
Minutes.AppID,
SUM(Minutes.Amount)
FROM Minutes
INNER JOIN Apps ON Apps.ID = Minutes.AppID
GROUP BY Apps.Name, Minutes.AppID

I am using mysql as database and saved time as time stamp of related posts in table, now i want to fetch the post made rrecently . How can i compare and fetch the post made recently?
you can fetch rows in descending order of your column (time_stamp).
ex:
SELECT * FROM Table_Name ORDER BY col_time_stamp DESC;
col_time_stamp : is the column
select top 1 * from posts order by timestamp desc
try this
SELECT * FROM Table_Name ORDER BY col_time_stamp DESC LIMIT 0;
