Selecting top x rows for each of the groupby clause

Hi Gurus (again).
I have this query to select the top 24 rows:
select * from
+(+
select proid, to_char((next_day(trunc(request_date, 'iw'), 'mon')-7), 'YYYY') as YEAR, to_char(request_date, 'IW') as WEEK,
next_day(trunc(request_date, 'iw'), 'mon')-7 as weekdate,
trunc(avg(case when report_date > request_date then ((report_date - request_date) * 24) end),1) as avg_ERT_hr, '24' as ERT_goal,
trunc(avg(case when response_date > request_date then ((response_date - request_date) * 24) end),1) as avg_IRT_hr, '48' as IRT_goal,
trunc(avg(case when deliver_date > request_date then ((deliver_date - request_date)) end),1) as avg_IDT_day, '0' as IDT_goal,
trunc(avg(case when complete_date > request_date then ((complete_date - request_date)) end),1) as avg_ORT_day, '0' as ORT_goal
from biw_hda_event
where request_date is not null
group by proid, to_char((next_day(trunc(request_date, 'iw'), 'mon')-7), 'YYYY'), to_char(request_date, 'IW'), next_day(trunc(request_date, 'IW'), 'MON')-7
order by 1 desc, 2 desc
+) where rownum <=24+
The problem here is that I have a group by "proid" clause in addition to the dates. My purpose is to be able to select the top 24 rows for each of the "proid" that is already grouped by the date. Essentially, the top 24 is the last 24 weeks pertaining to that "proid". How can I do this effectively without creating heaps of UNION clause for each of the "proid"?
thanks in advance

Select top 10 rows for each product

Hi,
I have to build a query in the following way:
I have a query like,
select dept, product, product_sold
from products
order by 1, 2 desc
But I have a requirement, not to show all the products in dept . I need to show only first 10 rows of each 'dept' column.
Please help me in acheiving this.

You would do something like this (untested):
select dept
, product
, product_sold
from (
   select dept
   , product
   , product_sold
   , row_number() over (
      partition by dept
      order by product
      , product_sold
   ) rn
   from products
where rn <= 10;Assuming that I have correctly guessed the ordering you require...

How to select top one in CDS view ?

I have tried following logic to select top one in CDS view but its giving error -
define view Cds_View_First_Reference as select top one CReferredObject from CDSVIEWCROSSREF

Hi Ruchi,
since you posted this question in "ABAP in Eclipse" I assume you are asking about CDS in ABAP. This is important because the CDS features sets in ABAP and (native) HANA are different.
Be that as it may,, SELECT TOP 1 is neither supported in the CDS implementation in ABAP nor in HANA.
In ABAP you might consider using the min() or max() function together with the appropriate GROUP BY clause in the CDS view (depending on what you want to achieve), but you can also easily "implement" this in the Open SQL statement which selects from your CDS view.
Using the additions SELECT SINGLE or UP TO 1 ROWS and an appropriate ORDER BY clause in Open SQL, you can achieve the same as SELECT TOP 1.
Unfortunately there is currently no possibility to define a view which delivers the TOP 1 which you can again use in another view ("view on view").
Kind regards
Chris

Can SELECT TOP have argument?

Newbie’s question, I believe.
I wanted to make a stored procedure to returns last several rows or last several hundred rows depending on the situation, so I started writing queries in order to copy/paste them into procedure. There are two queries, first works, but
second one shows syntax error in select statement. Can anyone tell me why, and how to go around this?
SELECT TOP 5 * FROM Table1 ORDER BY ID DESC
DECLARE @Counter as int
SET @ Counter = 5
SELECT TOP @ Counter FROM Table1 ORDER BY ID DESC

This works. But I still don?t realize what was wrong with my syntax. Do those () will convert what?s inside parameter to string so parser could read it correctly? What actually is going on here?
It's just the way it is. Originally there was only SELECT TOP n, where the value after TOP had to be a constant. Then they added the ability to have expression, but then they added the parens. This is so that you can say things like:
SELECT TOP (SELECT ... FROM ...) ... FROM
if you feel like.
The old syntax is deprecated but remains for compatibility reasons.

Hi,
Please read SQL and PL/SQL FAQ
Additionally when you put some code please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
From what I have found on MS SQL documentation it seems that TOP keyword limits the output to a specified percentage of total number of rows. In your case, having specified 100, you are returning 100% of rows.
So you can simply remove *TOP (100) PERCENT*
Regards.

Select top 10 percentage

Thanks a lot

Hi,
998093 wrote:
... What if I want to get, for example, the employees who are in the top 12% of the salaries? here we cannot use deciles (maybe we can but it won't be very nice).Actually, you can. How nice it will be depends on your data and your exact requirements.
Earlier, we said that the top 10% was the 10th of 10 buckets.
We could say that the top 12% is the last 12 of 100 buckets:
WITH     got_tenth     AS
     SELECT     last_name, salary
     ,     NTILE (100) OVER (ORDER BY salary)     AS hundredth
     FROM     hr.employees
SELECT       last_name, salary
FROM       got_tenth
WHERE       hundredth     > 100 - 12
ORDER BY salary     DESC
;I won't clutter up this message by showing the results for every query; I'll just report the total number of rows. The query I posted earlier (for the top 10%) produced 10 rows of output; the query immediately above produces 12. That's starting to bother me. There are 107 rows in hr.employees. (They all have a salary; don't forget to deal with NULLs in general.) The top 10% should contain 107 * .1 = 10.7 rows. Of course, this has to be rounded to an integer, so it would have been a little better if the top 10% showed 11 rows (since 11 is closer to 10.7 than 10 is), but it's not a real big problem. Likewise, the top 12% should have 107 * .12 = 12.84 rows, so 13 rows of output might be better, but 12 rows isn't too bad.
Now say we want to simplify the condition "WHERE     hundredth     > 100 - 12". Instead of taking the last 12 buckets in ascending order, let's take the first 12 buckets in descending order:
WITH     got_tenth     AS
     SELECT     last_name, salary
     ,     NTILE (100) OVER (ORDER BY salary DESC)     AS hundredth
     FROM     hr.employees
SELECT       last_name, salary
FROM       got_tenth
WHERE       hundredth     <= 12
ORDER BY salary     DESC
;The result set now contains 19 rows! Why? Because NTILE puts extra items (when there are extras) in the lower-numbered buckets. When there were 10 buckets, then buckets 1 trough 7 had 11 items each, and buckets 8 through 10 had 10 items. We were only dispolaying bucket #10, so we only saw 10 items. Now that there are 100 buckets, buckets 1 through 7 will have 2 items each, and buckets 8 through 100 will have 1 item each. When we numbered the buckets in ascending order, and took the last 12 buckets, we wound up with 12 * 1 = 12 rows, but when we numbered the buckets in descending order and took the first 12 buckets, we got (7 * 2) + (5 * 1) = 19 rows.
When you have R rows and B buckets, and R/B doesn't happen to be an integer, then NTILE will distribute the rows as equally as possible, but some rows will have 1 item more than others. When the ratio R/B is high, that might not be very significant, but when R/B gets close to 1, then you have situations like the one above, where the bigger buckets, although they have only 1 more item than the smaller buckets, are twice as big. Even worse is the situation where R/B is less than 1; then the last buckets will have 0 items.
So, as you noticed, NTILE isn't a good solution for all occasions. Here's a more accurate way, using the analytic ROW_NUMBER and COUNT functions:
WITH     got_analytics     AS
     SELECT     last_name, salary
     ,     ROW_NUMBER () OVER (ORDER BY salary DESC)     AS r_num
     ,     COUNT (*)     OVER ()                                AS n_rows
     FROM     hr.employees
SELECT       last_name, salary
FROM       got_analytics
WHERE       r_num / n_rows <= 12 / 100
ORDER BY salary     DESC
;This produces 12 rows.
If you want 13 rows (because 107 * .12 = 12.84 is closer to 13), then you can change the main WHERE clause like this:
WITH     got_analytics     AS
     SELECT     last_name, salary
     ,     ROW_NUMBER () OVER (ORDER BY salary DESC)     AS r_num
     ,     COUNT (*)     OVER ()                                AS n_rows
     FROM     hr.employees
SELECT       last_name, salary
FROM       got_analytics
WHERE       r_num     <= ROUND (n_rows * 12 / 100)
ORDER BY salary     DESC
;
