Duplicate Information with Different IDs

Duplicate Information with Different IDs
I am trying to sum monthly hours for wly timecards which have multiple
line items as tasks, but I am retrieving duplicate entries.
This is because a timecard can have a timecard_type of "r" (regular), or a
timecard_type of "c" (corrected).
If the timecard is corrected, the original with the timecard_type of "r"
still exists, but both time cards with duplicate information, have different
timecard IDs.
WHERE tc_type = 'r'
OR tc_type = 'c'
doesn't help me, so how can I get a monthly total of regular
timecards(timecard_type = 'r'), & corrected (timecard_type = 'c'),
and the original regular timecard is not returned, if it has been corrected.
I've got to think there's some way to use the timecard IDs.
When trying to use an "IF...ELSE", I get the error "Subquery returned more
than 1 value" because of the multiple line items.
Can someone please help?
p.s. There's a duplicate thread in SQL Server Reporting Services. Sorry for
the mis-hit.Untested, and guessing at your schema, but something like this should
do the trick:
SELECT timecard_id, SUM(hours)
FROM timecards_table
WHERE tc_type = 'c'
OR (tc_type = 'r' AND timecard_id NOT IN (SELECT timecard_id FROM
timecards_table WHERE tc_type = 'c'))
GROUP BY timecard_id|||You need to post DDL and some sample data.

The answer is you have to look at other columns to identify duplicate time
cards in order to exclude the ones that have been corrected. Without
knowing your data structures we can only guess.
I'll assume your table looks like this:
Create table timecard
(
timecardID integer primary key not null
, EmployeeID varchar(10) not null
, PayEndDate datetime not null
, Workdate datetime not null
, EarningCode varchar(3) not null
, HoursWorked decimal (4,2) not null
, timecard_type char(1) not null
)
I will also assume that you can have only one valid timecard per employee
per workdate. If this is not reality, adjust the criteria to match your
level of uniqueness. You can put the following logic into a view and then
report against it.
select a.employeeID
, a.payenddate
, a.workdate
, a.earningscode
, a.hoursworked
from timecard a
where a.timecard_type = 'c'
or
(
a.timecard_type = 'r'
and not exists (
select 1 from timecard b
where b.employeeid = a.employeeid
and b.payenddate = a.payenddate
and b.workdate = a.workdate
and b.timecard_type = 'c'
)
)

create table #timecard(emp_id int not null,
timecard_type char(1) not null check(timecard_type in ('r','c')),
hours int not null,
unique(emp_id, timecard_type))
go
insert into #timecard values(1,'r',40)
insert into #timecard values(1,'c',32)
insert into #timecard values(2,'r',40)
go
select r.emp_id, coalesce(c.hours, r.hours)
from
(select emp_id, hours from #timecard where timecard_type='r') r
left outer join
(select emp_id, hours from #timecard where timecard_type='c') c
on r.emp_id = c.emp_id
emp_id
-- --

2 40

query & it worked great! Thanks
