I am trying to get the average results 6 fileds, with 2 decimal points. The results are coming back as whole numbers.

Thanks


select QInstructorID_1 Instructor, AVG(((QInstructor_A_1 + QInstructor_A_2 + QInstructor_A_3 + QInstructor_A_4 + QInstructor_A_5 + QInstructor_A_6)/6)) Average from dbo.CE_Report where YEAR(QCourseStartDate_1) = 2012 AND QInstructor_A_6 is not null GROUP BY QInstructorID_1

An integer divided by an integer is an integer, so 4/3 = 1 , 3/2 = 1, 7/2 = 3, etc

select QInstructorID_1 Instructor
, AVG(((QInstructor_A_1 + QInstructor_A_2 + QInstructor_A_3 + QInstructor_A_4 + QInstructor_A_5 + QInstructor_A_6)*1.0/6)) Average
from dbo.CE_Report
where YEAR(QCourseStartDate_1) = 2012 AND QInstructor_A_6 is not null GROUP BY QInstructorID_1

so that red bit will change everything to a decimal

Thanks - works great. What if I want to format the answer to show two decimals?

Formatting should be done at the application layer but
Convert(Decimal(18,2), AVG((QInstructor_A_1 + QInstructor_A_2 + QInstructor_A_3 + QInstructor_A_4 + QInstructor_A_5 + QInstructor_A_6)/6.0))
