There was an example of the GROUP BY in my original post.
SELECT Reason, SUM([DTMIN])
FROM vwIG_DownTimeDetailsByPID
WHERE Reason = 'Electrical'
AND (
([Trans Date] BETWEEN '2024-01-02'AND '2024-01-09')
OR ([Trans Date] BETWEEN '2024-01-02' AND '2024-01-09')
OR ([Trans Date] <= '2024-01-02' AND [Trans Date] >= '2024-01-09')
)
GROUP BY Reason
