Sub-Select on MySQL - mysql

Question

I don't know if this is possible but I'm trying to make a select queries with a couple of JOINS with a WHERE statement. What I need is a field based on a particular WHERE and another field with different WHERE.
Current SQL query:
SELECT SUM(a.totaltime), b.user_name, MONTHNAME(a.date)
FROM a
JOIN c on c.id = a.id
JOIN b on b.userid = c.userid
LEFT JOIN d on a.projid = d.projectid
LEFT JOIN e on a.account_id = e.salesorderid
LEFT JOIN f on e.salesorderid = f.salesorderid
LEFT JOIN g on d.projectid = g.projectid
WHERE c.deleted != "1" AND YEAR(DATE(NOW())) AND ( f.cf_991 = '1' OR g.cf_990 = '1')
group by user_name,MONTHNAME(a.date);
This works fine but I need to include another field this time WHERE would be:
WHERE c.deleted != "1" AND YEAR(DATE(NOW())) AND ( f.cf_991 = '0' OR g.cf_990 = '0')
Any help is greatly appreciated thanks
EDIT:
CURRENT OUTPUT IS:
total_time username MONTHNAME(a.date)
22.5 admin April
21 admin June
15 max April
So the above is based on f.cf_991 = '1' OR g.cf_990 = '1'
What I need is this:
total_time username MONTHNAME(a.date) total_time_2
22.5 admin April 5
21 admin June 9
15 max April 13
total_time_2 is based on f.cf_991 = '0' OR g.cf_990 = '0'.

Answer 1

SELECT SUM(CASE WHEN f.cf_991 = '1' OR g.cf_990 = '1' THEN a.totaltime END) as total_time
, b.user_name, MONTHNAME(a.date)
, SUM(CASE WHEN f.cf_991 = '0' OR g.cf_990 = '0' THEN a.totaltime END) as total_time_2
FROM a
JOIN c on c.id = a.id
JOIN b on b.userid = c.userid
LEFT JOIN d on a.projid = d.projectid
LEFT JOIN e on a.account_id = e.salesorderid
LEFT JOIN f on e.salesorderid = f.salesorderid
LEFT JOIN g on d.projectid = g.projectid
WHERE c.deleted != "1"
AND YEAR(CURDATE()) = a_column_containing_a_date
AND (
( f.cf_991 = '1' OR g.cf_990 = '1')
OR
( f.cf_991 = '0' OR g.cf_990 = '0')
)
group by user_name,MONTHNAME(a.date);

Answer 2

Just try this
SELECT
SUM(if(f.cf_991 = '1' || g.cf_990 = '1',a.totaltime,0)),
SUM(if(f.cf_991 = '0' || g.cf_990 = '0',a.totaltime,0)),
b.user_name, MONTHNAME(a.date) FROM a
JOIN c on c.id = a.id
JOIN b on b.userid = c.userid
LEFT JOIN d on a.projid = d.projectid
LEFT JOIN e on a.account_id = e.salesorderid
LEFT JOIN f on e.salesorderid = f.salesorderid
LEFT JOIN g on d.projectid = g.projectid
WHERE c.deleted != "1" AND YEAR(DATE(NOW()))
and (( f.cf_991 = '1' OR g.cf_990 = '1') or( f.cf_991 = '0' OR g.cf_990 = '0') )
group by ser_name,MONTHNAME(a.date);
