I have table data like that you show in this screenshot:
and I have query like this so I don't want null values in output, means I don't want field like this
You can get the data next to each other using a trick with row_number(), so that you'll assign numbers to both + and - groups, and then group by it:
select
max(case when Parameter = '+' then Description end),
max(case when Parameter = '-' then Description end)
from (
select
*,
row_number() over (partition by Parameter order by Id) as RN
from
#tmp
) X
group by RN

I have a table name customers with two columns, case id and owner. I need to write a query to select random 5 caseids for every name in owner column.please help
For a start, you need something like:
SELECT TOP 5
ID,
[Case ID],
[Owner],
Rnd(-Timer()*[ID]) AS RandomRecord
FROM
[Cases]
ORDER BY
Rnd(-Timer()*[ID]);
to be used as a subquery filtered on OwnerID of your Owners' table.
I once posted an article on this with a lot more details:
Random Rows in Microsoft Access
You can use in:
select t.*
from t
where t.id in (select top 5 id
from t as t2
where t2.name = t.name
order by Rnd(-Timer()*[ID])
);
