I have to rotate a given table from an SQL Server but a normal pivot just doesn't work (as far as i tried). So has anybody an idea how to rotate the table into the desired format?
Just to make the problem more complicated, the list of given labels can vary and it is possible that a new label name can come into at any given time.
Given Data
ID | Label | Numerator | Denominator | Ratio
---+-----------------+-------------+---------------+--------
1 | LabelNameOne | 41 | 10 | 4,1
1 | LabelNameTwo | 0 | 0 | 0
1 | LabelNameThree | 21 | 10 | 2,1
1 | LabelNameFour | 15 | 10 | 1,5
2 | LabelNameOne | 19 | 19 | 1
2 | LabelNameTwo | 0 | 0 | 0
2 | LabelNameThree | 15 | 16 | 0,9375
2 | LabelNameFive | 19 | 19 | 1
2 | LabelNameSix | 17 | 17 | 1
3 | LabelNameOne | 12 | 12 | 1
3 | LabelNameTwo | 0 | 0 | 0
3 | LabelNameThree | 11 | 12 | 0,9167
3 | LabelNameFour | 12 | 12 | 1
3 | LabelNameSix | 0 | 1 | 0
Wanted result
ID | ValueType | LabelNameOne | LabelNameTwo | LabelNameThree | LabelNameFour | LabelNameFive | LabelNameSix
---+-------------+--------------+--------------+----------------+---------------+---------------+--------------
1 | Numerator | 41 | 0 | 21 | 15 | |
1 | Denominator | 10 | 0 | 10 | 10 | |
1 | Ratio | 4,1 | 0 | 2,1 | 1,5 | |
2 | Numerator | 19 | 0 | 15 | | 19 | 17
2 | Denominator | 19 | 0 | 16 | | 19 | 17
2 | Ratio | 1 | 0 | 0,9375 | | 1 | 1
3 | Numerator | 12 | 0 | 11 | 12 | | 0
3 | Denominator | 12 | 0 | 12 | 12 | | 1
3 | Ratio | 1 | 0 | 0,9167 | 1 | | 0
