We will be looking in this article as how we can add Total of a column in a table. Very often we require to have total of a column in a table. For example , we might need total sum of Salary column in the table.
We will be leveraging power of Groovy in accomplishing this task.
So lets see how we can do this.
Use Case :- Add a Total Salary Attribute below Salary column in Employees Table.
Considering that we have EmployeesView VO object which is based on Employees EO, go to attributes of VO and click add new attribute. Select "Add new Attribute". It will by default be transient. Give this attribute name as TotalSal.
Now go to View Accessors tab and click on green + sign to create new View Accessor.
Select EmployeesView from the first window and shuttle it so that you can see like below.
Do ok and it should be like below screenshot.
Now go to attributes tab and select the new transient attribute (TotalSal).
Give its Default value as Expression and give Groovy expression as EmployeesView1.sum("Salary") .
Create a new page. Drag and Drop EmployeesVO from data control and create a new read only table "without" TotalSal Attribute.
Now go to Salary Column in Structure and do a right click and select footer from facet as shown below.
Now from EmployeesView1 in DataControl, drag and drop TotalSal column in this new footer facet.
Now go to bindings and create a new binding for this variable.
And change the value of footer output text with this binding.
Save all and run this page.
Hope this was useful.
