# Creating A Percentage Column In Query Results

• ### Question

• I have a rather simple query whose output is the sum of column1 and the sum of column2.  I'm trying to add a third column to the query results that is in essence:

SumOfColumn1/(SumOfColumn1+SumOfColumn2) in percentage form

Any help would be greatly appreciated.  thank you in advance.

• Hi Karl ... so no sooner did I post my reply to you as I figured out the solution!  Here is the syntax and steps that I used to accomplish my end results:

Expr1: [SumOfColumn1]/([SumOfColumn1]+[SumOfColumn2])

then in the field where I entered the expression I right-clicked, then clicked properties, then changed the format to percent and VIOLA!! that did the trick.

Thank you for the help, your kick in the right direction was just what I needed to figure it out.

• Try this --

Sum(Column1)/(Sum(Column1+Column2)) / 100

Build a little, test a little

• Hi Karl, thanks so much for the help.  I've tried a couple of things and each time I don't get any results in the Expr1 field for my query.

I have column1 grouped by sum

I have column2 grouped by sum

Then for the third column I have the expression written out as you suggested in the field field of the design view of the query.  I don't get any errors when I run it, but when the query is run the Sum of Column1 shows as it should as well the sum of column2 shows as it should, but then the third column just says Expr1 without any results.  I've tried a few things with regards to the grouped by field in the design view but more often then not those result in errors.  Any thoughts?
