Answer 1

You can try this query.

SELECT 
ID,
MAX(Case When parameter='Age Group' then Value else '0' end) AS  AgeGroup,
MAX(Case When parameter='Trial Type' then Value else '0'end)AS  TrialType,
MAX(Case When parameter='Age Unit' then Value else '0'end)AS  AgeUnit
FROM teststack
GROUP BY ID 
ORDER BY ID
