SQL case statements to change values

This is my code to do part of what I want to do:

SELECT uID, ColumnName, ColumnResult
FROM table
UNPIVOT
(
ColumnResult
for ColumnName in (COL1,COL2,COL3)
 )u

This returns something like this:

Thanks

Solution

  • You can use the following query which replaces the column name with the new value:

    select uID,
  case ColumnName 
    when 'COL1' then 'columnOne'
    when 'COL2' then 'columnTwo'
    when 'COL3' then 'columnThree'
  end ColumnName, 
  ColumnResult
from TABLE
unpivot
(
  ColumnResult
  for ColumnName in (COL1,COL2,COL3)
)u;
