stored procedures can not be queried. My problem is this:
I want to select the rows that match a certain parameter.
From that I want to select the most current 20 rows (there is a date
field).
From that I want to select the lowest 10 rows based on a numeric
field.
Finally I want that to be input to a report and some calculations.
What this basically is the selection for USGA Golf Handicap Index. It
is the most current 20 rounds of golf by a golfer, then the best 10 of
those 20 and then finally the calculation.
Any help would be appreciated.Could be something like this. Here it is in SQL92:
SELECT S.employee_id, S.date_col, S.numeric_col
FROM Something AS S
LEFT JOIN Something AS T
ON S.employee_id = 1
AND T.employee_id = 1
AND (S.date_col < T.date_col
OR (s.date_col = T.date_col
AND S.numeric_col < T.numeric_col))
GROUP BY S.employee_id, S.date_col, S.numeric_col
HAVING COUNT(T.employee_id)<10 ;
Or, if you don't mind using the proprietary TOP modifier in SQL Server:
SELECT TOP 10 WITH TIES
employee_id, date_col, numeric_col
FROM Something
WHERE employee_id = 1
ORDER BY date_col DESC, numeric_col DESC ;

explain this to me but I just couldn't get it. You example allowed me
to do it both ways. I don't mind using the Top 10 with TIES but never
heard of it before.
Again thanks, makes for cleaner than temporary tables.
