The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.

Hi Martijn,

select REFKL, ORDAT, ORDNR
from TOVF
order by
case :SortCode
when 'A' then ' ORDAT asc '
when 'D' then ' ORDAT desc '
else ' REFKL asc '
end
limit 10;
This ORDER BY expression doesn't work - as you can only have an expression instead of a column name. So this should work:
order by
case :SortCode when 'A' then ORDAT end asc,
case :SortCode when 'D' then ORDAT end desc,
case when :SortCode not in ('A', 'D') then REFKL end asc
Lets look into it in detail, when :SortCode is set - lets assume its 'D' then the cases will evaluate into this
order by
null asc,
ordat desc,
null asc
So - as the cases, which are not true, evaluate to null, their sorting doesn't effect the result set sequence.
With a case, you can switch between 2 or more columns to sort, but you cannot switch the ascending or descending.
