Friends,
Can anyone give me the best way to solve the following challenge.
I have two tables in my MS SQLserver database. Table A has this dataset:
code_id code operations_descr
1 M Mob/Demob
2 T Transit
3 O Operation
4 S Standby
5 W WOW
6 C Crew Change
7 B Breakdown
8 R Maintenance
Table B has this dataset:
code_id operations_duration
3 125
3 10
2 1304
I want a new recordset where the sum of the operations_duration from table B
grouped on code_id is combined with the right code_id in table A, like this:
code_id code operations_descr total_operations_duration
1 M Mob/Demob 0
2 T Transit 1304
3 O Operation 135
4 S Standby 0
5 W WOW 0
6 C Crew Change 0
7 B Breakdown 0
8 R Maintenance 0
Thank you for any assistance!

Systems AnalystI've assumed that the first table is called "Operations" and that the second
one is called "OperationsDuration". Here is the query:
Select O.Code_ID, O.Code, O.Operations_Descr,
Sum(OD.Total_Operations_Duration)
From Operations O, OperationsDuration OD
Where O.Code_ID = OD.Code_ID
Group By O.Code_ID, O.Codel O.Operations_Descr
Best regards,

Select O.Code_ID, O.Code, O.Operations_Descr,
Sum(ISNULL(OD.Total_Operations_Duration,0)) as Total_Operations_Duration
From [Table A] O
LEFT JOIN [Table B] OD ON O.Code_ID = OD.Code_ID
Group By O.Code_ID, O.Codel O.Operations_Descr

The code you gave me works well. But it is more to it.
The data is collected from a survey vessel working in the North Sea and the
tables contains data from daily reports sent from the vessel. Table B stores
operations duration for each day where records from a given day share the
same report_id. When I take your code and add: "Where OD.report_id =
@.reportId" and supply report_id = 2, the result set exclude code lines from
table A that are not in table B like this:
code_id code operations_descr Total_Oper
ations_Duration
2 T Transit 1304
3 O Operation 135
Your advice is appreciated!

SELECT code_id, code, operations_descr,
operations_duration = (SELECT SUM(total_operations_duration)
FROM TABLEB
WHERE code_id = TABLEA.code_id
GROUP BY code_id
)
FROM TABLEA

I am not sure where report_id comes from as it was not mentioned in the
original post. You may want to check out
http://www.aspfaq.com/etiquette.asp?id=5006 on how to post DDL and example
data.
Try:
Select O.Code_ID, O.Code, O.Operations_Descr,
Sum(ISNULL(OD.Total_Operations_Duration,0)) as Total_Operations_Duration
From [Table A] O
LEFT JOIN [Table B] OD ON O.Code_ID = OD.Code_ID AND OD.report_id = @.reporti
d
Group By O.Code_ID, O.Codel O.Operations_Descr

When I moved the report_id qualifyer away from the "Where" clause and into
the Join statement I got what I wanted.
