[Solved] teradata sql pivot multiple occurrences into additional columns
I have something like this:
ID Result 1 value1 2 value1 2 value2 3 value1 4 value1 4 value2 4 value3
And I’d like to return something like this:
ID Result1 Result2 Result3 1 value1 2 value1 value2 3 value1 4 value1 value2 value3
I’ve searched on pivots and concats and breaks and I just can’t find a simple, sensible solution.
Unfortunately Teradata doesn’t have a PIVOT function but you can use an aggregate function with a CASE expression to get the result.
select id, max(case when seq =1 then result end) result1, max(case when seq =2 then result end) result2, max(case when seq =3 then result end) result3 from ( select id, res, row_number() over(partition by id order by result) seq from yourtable ) d group by id order by id;
If you have more values for each ID, then you can add more CASE expressions.
