Show SQL Calculation as Percentage

Posted on 2007-11-23

I have this code

(dbo.tblBTLSurvey.NewBusinessQ1 + dbo.tblBTLSurvey.NewBusinessQ2 + dbo.tblBTLSurvey.NewBusinessQ3) / 80 AS sPercent

and when I run it it  sPercent shows as 0.

This is because the actual calcualtion is    12 / 80 = 0.15


so SQL rounds it off to 0


What I want to achieve is for sPercent to show 15%  


Can anyone advise me on this?

Thanks

SELECT     dbo.tblBTLSurvey.NewBusinessQ1 + dbo.tblBTLSurvey.NewBusinessQ2 + dbo.tblBTLSurvey.NewBusinessQ3 AS total_score, 
                      (dbo.tblBTLSurvey.NewBusinessQ1 + dbo.tblBTLSurvey.NewBusinessQ2 + dbo.tblBTLSurvey.NewBusinessQ3) / 12 AS sPercent, 
                      dbo.vwSurveyCount.CompletedSurveys
FROM         dbo.tblBTLSurvey CROSS JOIN
                      dbo.vwSurveyCount

I mean for 15 %
just do this
(dbo.tblBTLSurvey.NewBusinessQ1 + dbo.tblBTLSurvey.NewBusinessQ2 + dbo.tblBTLSurvey.NewBusinessQ3) / 80*100 AS sPercent
Or or 15.00 %
(dbo.tblBTLSurvey.NewBusinessQ1 + dbo.tblBTLSurvey.NewBusinessQ2 + dbo.tblBTLSurvey.NewBusinessQ3) / 80.00*100.00 AS sPercent

Hi,

/ (Divide) operator in Books online:

If an integer dividend is divided by an integer divisor, the result is an integer that has any fractional part of the result truncated.

 
SELECT     dbo.tblBTLSurvey.NewBusinessQ1 + dbo.tblBTLSurvey.NewBusinessQ2 + dbo.tblBTLSurvey.NewBusinessQ3 AS total_score, 
                    (dbo.tblBTLSurvey.NewBusinessQ1 + dbo.tblBTLSurvey.NewBusinessQ2 + dbo.tblBTLSurvey.NewBusinessQ3) / 0.12 AS sPercent, 
                      dbo.vwSurveyCount.CompletedSurveys
FROM         dbo.tblBTLSurvey CROSS JOIN
                      dbo.vwSurveyCount

The answer was


SELECT     dbo.tblBTLSurvey.NewBusinessQ1 + dbo.tblBTLSurvey.NewBusinessQ2 + dbo.tblBTLSurvey.NewBusinessQ3 AS total_score, 
                      CAST(CONVERT(decimal(18, 2), dbo.tblBTLSurvey.NewBusinessQ1 + dbo.tblBTLSurvey.NewBusinessQ2 + dbo.tblBTLSurvey.NewBusinessQ3) 
                      / 80 AS varchar) + '%' AS sPercent, dbo.vwSurveyCount.CompletedSurveys
