Hi all

not exactly sure what I am supposed to do here if it is pivot or unpivot. I have a data set where all columns after the first column need to pivot but the first column then needs to relate the value it has against the original and show the duplicate value, as shown below if you don't understand the requirement:


Number    Column1    Column2    Column3
======    =======    =======    =======
1         20         60         30
2                    12         8
3         5          60         30 
4         16                    67


Number    New Col1   Value  
======    =======    =======    
1         column1    20  
1         column2    60      
1         column3    30
2         column1
2         colunm2    12
2         column3    8
...
...
...

Any thoughts on the steps I need to take would be most helpful.

I think it was unpivot I had to use.

its indeed unpivot


SELECT Number,[New Col],[Value]
FROM (SELECT Number,
ISNULL(Column1,'') AS Column1,
ISNULL(Column2,'') AS Column2,
ISNULL(Column3,'') AS Column3
FROM Table
)t
UNPIVOT([Value] FOR [New Col1] IN ([Column1],[Column2],[Column3]))u
