Question

I have a database structure like this

rowid   deltaValue  Applicable
1        r            n/d
1        w            n/d
1        m            n/d
2        r            n/d
2        w            n/d
2        m            n/d
3        r            n/d
3        w            n/r
3        m            n/d

so basically I want to only select the last group of ‘rowid’, ie rowid=3. This is because it is the only group that has a combination of n/d, n/r

is there a tsql query that will just look at the combination and pull the group (ie, the rowid).
Here is what I have so far:

select  *
from table
where 1=1
and deltaValue in ('r','w','m')
and ((   1=(case when [DeltaValue] = 'r' and [Applicable]='n/r' then 1 else 0 end)
     and 1=(case when [DeltaValue] = 'w' and [Applicable]='n/d' then 1 else 0 end)
     and 1=(case when [DeltaValue] = 'm' and [Applicable]='n/d' then 1 else 0 end)
     ) OR
     (   1=(case when [DeltaValue] = 'r' and [Applicable]='n/d' then 1 else 0 end)
     and 1=(case when [DeltaValue] = 'w' and [Applicable]='n/r' then 1 else 0 end)
     and 1=(case when [DeltaValue] = 'm' and [Applicable]='n/d' then 1 else 0 end)
     ) OR
     (   1=(case when [DeltaValue] = 'r' and [Applicable]='n/d' then 1 else 0 end)
     and 1=(case when [DeltaValue] = 'w' and [Applicable]='n/d' then 1 else 0 end)
     and 1=(case when [DeltaValue] = 'm' and [Applicable]='n/r' then 1 else 0 end)
     )
    )

Output:

3        r            n/d
3        w            n/r
3        m            n/d

Answer 1

Try this:

with temp as
(
    SELECT t.rowid
    FROM myTable t
    GROUP BY t.rowid
    HAVING COUNT(CASE WHEN Applicable= 'n/d' THEN 1 END) > 0
       AND COUNT(CASE WHEN Applicable= 'n/r' THEN 1 END) > 0;
)
select * from MyTable as mt
INNER JOIN temp as t
ON mt.RowId = t.RowId
