Introduction

Write a query to get 5 % of admission fees from Michael, 10% of admission fees from John and for other 15 % of admission fees as 'Deducted_Admission_fee' from tblStudent table. I have used Microsoft SQL server 2008 R2 for the following demo.

  1. SELECT FirstName, CASE FirstName WHEN 'Michael'
  2. THEN Admission_fee * .10 WHEN 'John' THEN Admission_fee * .15
  3. ELSE Admission_fee * .15 END "Deducted_Admission_fee" FROM tblStudent
