Question

In printing out some calculated values that involve division to calculate a percentage I’m receiving a divide by zero error. I’m not worried that it is happening, I just want to know how I can print a 0 along with the rest of the line instead of it printing the error, ie 0%.

This is my print statement:

print cast(@usercode as varchar) + ' ' + @username + space(4) +
    'cr' + space(4) + cast(@totalUserVolumeCredit as varchar) + 
    space(4) + cast(@userUnpaids as varchar) + space(4) + 
    cast(@userDisputes as varchar) + space(4) + 
    cast((@userUnpaids + @userDisputes) as varchar) + space(4) + 
    cast(((@userUnpaids + @userDisputes)/@totalUserVolumeCredit) as varchar) + --error line
    space(4) + cast(@userRedirectsVolume as varchar);

print cast(@usercode as varchar) + ' ' + @username + space(4) +
     'cr' + space(4) + cast(@totalUserVolumeCredit as varchar) + 
     space(4) + cast(@userUnpaids as varchar) + space(4) + 
     cast(@userDisputes as varchar) + space(4) + 
     cast((@userUnpaids + @userDisputes) as varchar) + space(4) + 
     case @totalUserVolumeCredit when 0 then '0' else
        cast(((@userUnpaids + @userDisputes)/@totalUserVolumeCredit) as varchar)
     end +
     space(4) + cast(@userRedirectsVolume as varchar);
