# How To Find Average In Calculated Column Using Calculation View In SAP HANA

In this blog I am going to explaining about How To Find Average.

Average : The sum of all of the numbers in a list divided by the number of items in that list.

In my calculation view I am taking student four subject marks and finding the average to that marks using Calculated Column.

**Calculated Column : **It is an additional column which can be created by us, the results of which are calculated at run time based on the existing column and using either functions, input parameters and constants.

Following are the steps to implement “How To Find Average In Calculated Column Using Calculation View In SAP HANA”.

**Step 1:** Create one Table with the name **“STUDENT_DETAILS”** in our schema with following structure

Insert Below Values into our Table

**Step 2**: Create Calculation view in our package with the name **“STUDENT_CLASS”**

Select **STUDENT_DETAILS** table in projection and Select the all columns.

Create One calculated column for Calculating Average.

Add projection to aggregation and select the calculated columns **MARKS_PERCENTAGE**

**Save and Activate** the View.

So you are saying adding the value of 4 subjects and dividing by 4 is different from how an Average is normally calculated?

No, Both are same.
