$aresult=mysql_query(select sum(deposit)-sum(refund)as balance from dps where member='$row[id]');
$arow=mysql_fetch_array($aresult);
echo $arow[balance];
$bresult=mysql_query(select sum(mvs_total)as mvs_balance from mvs where member='$row[id]' and date1<='2016-09-01');
$brow=mysql_fetch_array($bresult);
}while($row=mysql_fetch_array($result));
its taking too much time
how to avoid sub query or how can i save time
advice plz
Thanks in advance
Try this,
select sum(deposit)-sum(refund) from dps JOIN member ON (dps. member = member.id) WHERE team='1';

but i get this error " Subquery returns more than 1 row" when i want no of callers
pls help me to solve it
Change your query to:
SELECT cca.id, cca.username,
(SELECT COUNT(DISTINCT cccr.cc_caller_id)
FROM cc_caller_requirements AS cccr
WHERE cccr.cc_agent_id = cca.id
) AS num_of_callers,
(SELECT COUNT(ccns.id)
FROM cc_notifications AS ccns
WHERE ccns.cc_agent_id = cca.id
AND ccns.cc_notification_type_id = 'sms') AS sms,
(SELECT COUNT(ccnm.id)
FROM cc_notifications AS ccnm
WHERE ccnm.cc_agent_id = cca.id
AND ccnm.cc_notification_type_id = 'mail') AS mail,
(SELECT COUNT(ccna.id)
FROM cc_notifications AS ccna
WHERE ccna.cc_agent_id = cca.id
AND ccna.cc_notification_type_id = 'courier') AS courier
FROM cc_agents AS cca
GROUP BY cca.id
I have two tables tc_users and tc_timeclock. I want to grab the current status of each active user. But only those that have made an update (clocked in or out) within the last 12 hours. I have gotten as far as figuring out how to grab all of the updates within the last 12 hours but not how to narrow it down to just the last one for each user.
Here are my tables:
tc_users:
user_id | first_name | last_name | active
-----------------------------------------
1 | Frank | Zappa | 1
2 | John | Mcneely | 1
3 | Bill | Mckenna | 1
4 | Mark | langdon | 1
5 | Steve | Mcalister | 0
6 | William | Stevens | 1
7 | John | Jones | 0
tc_timeclock:
tc_id | user_id | status | time_stamp
-------------------------------------
1 | 1 | IN | 2012-11-28 09:00:25
2 | 2 | IN | 2012-11-28 09:01:25
3 | 3 | IN | 2012-11-26 09:03:25
4 | 4 | IN | 2012-11-28 09:21:25
5 | 5 | IN | 2012-11-28 09:01:12
6 | 6 | IN | 2012-11-28 09:47:13
7 | 7 | IN | 2012-11-12 09:00:22
8 | 7 | OUT | 2012-11-12 09:03:28
9 | 5 | OUT | 2012-11-28 09:21:25
10 | 6 | OUT | 2012-11-28 11:47:13
11 | 3 | OUT | 2012-11-26 11:03:25
12 | 2 | OUT | 2012-11-28 11:01:25
13 | 1 | OUT | 2012-11-28 11:27:25
14 | 4 | OUT | 2012-11-28 11:21:25
15 | 4 | IN | 2012-11-28 12:21:25
16 | 1 | IN | 2012-11-28 12:27:25
17 | 3 | IN | 2012-11-26 12:03:25
18 | 6 | IN | 2012-11-28 12:47:13

22 | 3 | OUT | 2012-11-26 17:03:25
23 | 2 | OUT | 2012-11-28 17:01:25
So far This is the query I have come up with :
if now = 2012-11-28 18:00:00
SELECT first_name, last_name, status, time_stamp
FROM tc_timeclock
INNER JOIN tc_users
ON tc_timeclock.user_id = tc_users.user_id
WHERE tc_users.active = 1
AND tc_timeclock.time_stamp BETWEEN '2012-11-28 06:00:00' AND '2012-11-28 18:00:00'
This displays everything within the last 12 hours like so:
first_name | last_name | status | time_stamp
-----------------------------------------------------
Frank | Zappa | IN | 2012-11-28 09:00:25
John | Mcneely | IN | 2012-11-28 09:01:25
Mark | langdon | IN | 2012-11-28 09:21:25
William | Stevens | IN | 2012-11-28 09:47:13
William | Stevens | OUT | 2012-11-28 11:47:13
John | Mcneely | OUT | 2012-11-28 11:01:25
Frank | Zappa | OUT | 2012-11-28 11:27:25
Mark | langdon | OUT | 2012-11-28 11:21:25
Mark | langdon | IN | 2012-11-28 12:21:25
Frank | Zappa | IN | 2012-11-28 12:27:25
William | Stevens | IN | 2012-11-28 12:47:13
John | Mcneely | IN | 2012-11-28 12:01:25
Frank | Zappa | OUT | 2012-11-28 17:27:25
Mark | langdon | OUT | 2012-11-28 17:21:25
John | Mcneely | OUT | 2012-11-28 17:01:25
The logic I am looking for:
Grab the first and last name, current status and time the status was logged for each active user within the last 12 hours.
So output should be:
first_name | last_name | status | time_stamp
Frank | Zappa | OUT | 2012-11-28 17:27:25
John | Mcneely | OUT | 2012-11-28 17:01:25
Mark | langdon | OUT | 2012-11-28 17:21:25
William | Stevens | IN | 2012-11-28 12:47:13
User 5 (Steve Mcalister) and 7 (John Jones) are not active so they are not displayed.
User 3 (Bill Mckenna)has no activity within the last 12 hours so he is also no diplayed.
Am I missing something really simple? (I am sure I am)
I have a work around if there is not a simple solution, I could always add two columns to the tc_users table: (tc_users.current_status, and tc_users.status_time) and simply make those the same as the last entry into the tc_timeclock table.
That way I could easily select them, I don't like the idea of making the data redundant though if I don't have to.
Something like this might work for you.
SQL:
SELECT `tc_users`.`first_name`, `tc_users`.`last_name`, `tc_timeclock`.`status`, `temp_table`.`last_updated`
FROM `tc_users`
INNER JOIN `tc_timeclock`
ON `tc_users`.`user_id`=`tc_timeclock`.`user_id`
INNER JOIN (
SELECT `user_id`, MAX(`time_stamp`) AS `last_updated` FROM `tc_timeclock` GROUP BY `user_id`
) AS `temp_table`
ON `tc_users`.`user_id`=`temp_table`.`user_id`
AND `tc_timeclock`.`time_stamp`=`temp_table`.`last_updated`
WHERE `tc_users`.`active`!=0
AND `temp_table`.`last_updated`>(NOW() - INTERVAL 12 HOUR);
OUT:
+------------+-----------+--------+---------------------+
| first_name | last_name | status | last_updated |
+------------+-----------+--------+---------------------+
| William | Stevens | IN | 2012-11-28 12:47:13 |
| Frank | Zappa | OUT | 2012-11-28 17:27:25 |
| Mark | langdon | OUT | 2012-11-28 17:21:25 |
