    Is there any easier way to do this sum/divide without having to put results of sum in a temp table first? Trying to do it all in one query give me:

    Cannot perform an aggregate function on an expression containing an aggregate or a subquery.

    SELECT Distinct LEFT(CONVERT(DateTime, IndexDate , 110), 11)AS IndexDate,

    COUNT(*) AS No_Records,

    Round(AVG(Test1),2) As Test1_AVG,

    Round(AVG(Test2),2) AS Test2_AVG,

    SUM(t_complete/COUNT (*)) As Percent_Complete

    FROM TestScores.dbo.Analysis

    Group by IndexDate

    You can't do it like that because you have an aggregate within an aggregate.

    Try this.

    SUM(t_complete)/COUNT (*) As Percent_Complete
