help me in forming an sql query - sql-server

Question

i have two tables .. one is a master table and other one is an daily report table.
Master table :
machine_id Machinename
1 abc
2 def
3 ghi
4 jkl
ven_fullreportmaster :
entry_date machine_id description_id tot_time shift_id
20110613 1 1 10 1
20110613 2 2 9 2
20110614 1 1 10 1
20110614 1 2 9 2
20110614 3 3 5 3
20110614 2 4 10 1
20110614 2 1 9 2
20110614 2 5 5 3
now, i want to retrieve the data from the daily report table that it should contain all the machine names with tot_time and entry_date..
i have used this query to retrieve the data,
select entry_date,
machinename,
(IsNull(cast(TotalMins / 60 as varchar(24)),'0') + ':' + IsNull(cast(TotalMins % 60 as varchar(24)),'0')) as TotalHrs--, shift_type
from (
select vm.machinename , vfrm.entry_date,
sum(case when vfrm.description_id in ('1','2','3','4','5') then DateDiff(mi, 0, total_time) else '0' end) as TotalMins
--vsm.shift_type
from ven_fullreportmaster vfrm
inner join ven_machinemaster vm on vm.machine_id = vfrm.machine_id
inner join ven_shifttypemaster vsm on vsm.shift_id = vfrm.shift_id
where vfrm.entry_date = '20110614'
-- and vfrm.shift_id in (1,2,3)
group by machinename, vfrm.entry_date --, vsm.shift_type
) as SubQueryALias group by entry_date, machinename,TotalMins --,shift_type
when i run the above query, i am getting details for machine-id 1 , 2,3 alone..
output:
entry_date machineid TotalHrs
2011-06-14 00:00:00.000 1 19:0
2011-06-14 00:00:00.000 2 24:0
2011-06-14 00:00:00.000 3 5:0
i need to get machine_id =4 value as 0 in TotalMins for each shift.. how to resolve it..plz help me ..
expected output:
entry_date machineid TotalHrs
2011-06-14 00:00:00.000 1 19:0
2011-06-14 00:00:00.000 2 24:0
2011-06-14 00:00:00.000 3 5:0
**2011-06-14 00:00:00.000 4 0:0**
thanks and regards

Answer 1

Try using left joins instead of inner joins, that should get machine #3 to appear even though it has no entries in the second table.

Answer 2

You are searching for records with a specific date but there is no entry for 20110614 in your reporting table.
One solution is to add records to your select using a UNION with an initial SUM of'0'.
These fake records will not throw off your existing SUM.
They will show up where there's missing data with '0'.
SQL Statement
SELECT entry_date
, machinename
, (ISNULL(CAST(TotalMins / 60 AS VARCHAR(24)),'0') + ':' + ISNULL(CAST(TotalMins % 60 AS VARCHAR(24)),'0')) AS TotalHrs--, shift_type
FROM (
SELECT vm.machinename
, vfrm.entry_date
, SUM(case when vfrm.description_id in ('1','2','3','4','5') THEN DATEDIFF(mi, 0, total_time) else '0' END) AS TotalMins --vsm.shift_type
FROM ven_fullreportmaster vfrm
INNER JOIN ven_machinemaster vm on vm.machine_id = vfrm.machine_id
INNER JOIN ven_shifttypemaster vsm on vsm.shift_id = vfrm.shift_id
WHERE vfrm.entry_date BETWEEN '20110614' AND '20110615'
GROUP BY
machinename
, vfrm.entry_date --, vsm.shift_type
UNION ALL
SELECT DISTINCT vm.machinename
, vfrm.entry_date
, '0'
FROM ven_machinemaster vm
CROSS APPLY ven_fullreportmaster vfrm
WHERE vfrm.entry_date BETWEEN '20110614' AND '20110615'
) AS SubQueryALias
GROUP BY
entry_date
, machinename
, TotalMins --,shift_type

Answer 3

Instead of:
from ven_fullreportmaster vfrm
inner join ven_machinemaster vm on vm.machine_id = vfrm.machine_id
inner join ven_shifttypemaster vsm on vsm.shift_id = vfrm.shift_id
where vfrm.entry_date = '20110614'
can you try this LEFT JOIN ? Note the moving of the condition from WHERE to the ON clause:
FROM ven_machinemaster vm
LEFT JOIN ven_fullreportmaster vfrm
ON vm.machine_id = vfrm.machine_id
AND vfrm.entry_date = '20110614'
INNER JOIN ven_shifttypemaster vsm
ON vsm.shift_id = vfrm.shift_id
or:
FROM ven_machinemaster vm
LEFT JOIN ven_fullreportmaster vfrm
ON vm.machine_id = vfrm.machine_id
AND vfrm.entry_date = '20110614'
LEFT JOIN ven_shifttypemaster vsm
ON vsm.shift_id = vfrm.shift_id
