如何在Pentaho Report Designer的开放式公式中使用多个条件？

Question

For single condition it is correct but if there is multiple condition hard to customize in open formula. For example i want grading like A,B,C .I did such but doesn't work?

Code tried:

=IF([total]>90;"A";0 IF(OR([total]<80 ; [total]<=90);"B";0; IF(OR([total]<60 ; [total]<=70);"C";0; )))

Answer 1

Try the below in the open formula section:

=IF([total]>90;"A";IF(OR([total]<80 ; [total]<=90);"B";"C"))

Since there is a nested looping condition you would need to place the inner condition inside the ELSE part of the Outer Condition.

Also i assume you need to display the grade against the marks scored by a student. So You can take a "Label" into the details section of the report. Open the Attribute section of the label and inside the value part, use the above formula. Check the image below: (highlighted)

Hope it helps :)
