Group by doesnt work

Group by doesnt work. I need to add time for particular user. time is the 3rd column of result set posted below. first is the quantity

SELECT
sum(woitem.qtytarget) AS woitemtotal, sysuser.username as USERNAME, timeworked.info as timetaken

FROM mo
INNER JOIN moitem ON mo.id = moitem.moid
LEFT JOIN wo ON moitem.id = wo.moitemid
LEFT JOIN woitem ON wo.id = woitem.woid AND woitem.typeid = 10
LEFT JOIN SYSUSER ON mo.userid = sysuser.id
left join customdecimal timeworked on timeworked.recordid = mo.id
WHERE cast(wo.datestarted as date) = '10-21-2015'
group by sysuser.username

You probably need to sum the time (timeworked.info)

It gives different result. Instead of showing xyz = 2 hours, it shows xyz = 5 hours

it should give a different result -- the correct one

Different but it gives wrong result.

then please post the source data and the result you expect. Your original query neither groups by timeworked.info nor aggregates it. You must do one or the other

Individually, I get correct. Like for example,

gbritton : 0.2
gbritton : 0.8
gbritton : 1.0
when I group or sum, it should give
gbritton : 2.0 but it gives 5.0

Tried grouping, but gives wrong result. How do I aggregate it? How do I give source data?

post your sample data and grouped query. this works:

select nm, sum(val)
from 
(select *
from (values ('gbritton', 0.2), ('gbritton', 0.8), ('gbritton', 1.0))v(nm, val)
) _
group by nm

There are many. I cant manually enter the values

just a subset, please. A subset that demonstrates the problem, that is. Also, you can copy and paste them -- no need to enter by hand

This is the grouped query

select distinct sysuser.username as WOUser, sum(timeworked.info) as timeworked, sum(woitem.qtytarget) AS woitemtotal

from po
inner join trackinginfo lot on lot.info = po.num and lot.tableid = -355941248
inner join woitem on lot.recordid = woitem.id
inner join wo on woitem.woid = wo.id AND woitem.typeid = 10
inner join part on woitem.partid = part.id
inner join product on product.partid = part.id
inner join moitem on wo.moitemid = moitem.id
inner join mo on moitem.moid = mo.id
left join sysuser on sysuser.id = wo.userid
left join customdecimal timeworked on timeworked.customfieldid = 15 and timeworked.recordid = mo.id
WHERE cast(wo.datestarted as date) = '2015-10-21'
group by sysuser.username , timeworked.info
order by sysuser.username
