AGENT DB TABLE
agent_id agent_name company_name
-------- ---------- -----------
1 AAA XXX
2 BBB YYY
3 CCC ZZZ
4 DDD XYZ
DRIVER DB TABLE
agent_id driver_id driver_name last_viewed
-------- ---------- ----------- -----------
2 1 EEE 1
2 2 FFF 0
2 3 GGG 0
1 4 HHH 0
3 5 III 1
3 6 JJJ 1
I WANT THE OUTPUT LIKE THIS
Agent Details Driver details
1, AAA, 1 Drivers (0 active | 1 idle)
Company name
2, BBB, 3 Drivers (1 active | 2 idle)
Company name
3, CCC, 2 Drivers (2 active | 0 idle)
Company name
I have tried this below query
$sql="SELECT a.*,d.*, COUNT(d.driver_id) AS drivers_count FROM ta_agent a JOIN ta_drivers d USING(agent_id) GROUP BY a.agent_id";
I want to show active and idle status of the driver based on last_viewed
column. For example agent_id 2 have three drivers (1,2,3) and those 3 drivers have 1,0,0 in their last_viewed column. So, i want to show the output like this 1 active and 2 idle...
Is this what you are looking at ?
select
concat(
a.agent_id,' ',a.agent_name,' ',a.company_name
) as `Agent Details`,
concat(
COUNT(d.driver_id),' Drivers (',
' Active ',sum(d.last_viewed = 1)
,' | ',sum(d.last_viewed = 0 ),' idle ) '
)as `Driver details`
FROM AGENT a
LEFT JOIN DRIVER d USING(agent_id)
GROUP BY a.agent_id
UODATE : from last comment
I don't want Driver Details -> 1 Drivers ( Active 0 | 1 idle ) I want Number of Drivers -> 1 Drivers, Active -> 0, Idle -> 1
select
concat(
a.agent_id,' ',a.agent_name,' ',a.company_name
) as `Agent Details`,
concat ( COUNT(d.driver_id),' ',' Drivers') as `Number of Drivers`,
sum(d.last_viewed = 1) as `Active`,
sum(d.last_viewed = 0) as `Idle`
FROM AGENT a
LEFT JOIN DRIVER d USING(agent_id)
GROUP BY a.agent_id
try this,.
select a.agent_id, a.agent_name, a.company_name, ifnull(cnt_all,0) total_drivers,ifnull(cnt_active,0) active_drivers, ifnull(cnt_idle,0) idle_drivers
from agent a left join (select agent_id, count(*) cnt_all
from driver
group by agent_id) cnt on a.agent_id=cnt.agent_id
left join (select agent_id, count(*) cnt_idle
from driver
where last_viewed=0
group by agent_id) idle on a.agent_id=idle.agent_id
left join (select agent_id, count(*) cnt_active
from driver
where last_viewed=1
group by agent_id) active on a.agent_id=active.agent_id
