Month Title Total
June A 1069
June B 1175

I would like the Title A to calculate as below:

Title A / Title B * 100 to get in percentage. Result should be as below:

Month Title Total
June A 91%
June B 1175

how can i do that?

[code]
SELECT [Month],Title,
Total*100.0/SUM(Total) OVER (PARTITION BY [Month]) AS [Total%]
FROM Table
[/code]

so you just want percentage only if its Title A?

then you can do this small modification


SELECT [Month],Title,
CASE WHEN Title='A'  THEN Total*100.0/SUM(CASE WHEN Title='B' THEN Total ELSE 0 END) OVER (PARTITION BY [Month]) ELSE Total END AS [Total]
FROM Table
