How to get one record from a range in an sql view based on the value of a field in another table
Posted on 2013-12-20
Hi there:
I have an Employees table with the fields called EmployeeName and YearsOfService. I have another table called Bonus that contains the fields: MinimumYears and BonusAmt. I want to create a view that displays the EmployeeName, YearsOfService and BonusAmt (one record per employee).
The Bonus table has the values:
MinimumYears | Bonus
0 | 0
2 | 1000
4 | 2800
6 | 4000
Two records in the Employees table may read:
EmployeeName | YearsOfService
Barry Blue | 2.65
Wayne Brown | 4.80
Greg White |1.94
The final view should read:
EmployeeName | YearsOfService | BonusAmt
Barry Blue | 2.65 | 1000
Wayne Brown | 4.80 | 2800
Greg White |1.94 | 0
So, what would be the SQL statement to get the required results?

Try this
-- If you want view, then only include create view
create view bonusview as
select a.EmployeeName,a.YearsOfService,(select max(b.bonus) from Bonus_Table b where b.MinimumYears < a.YearsOfService) BonusAmt
from Employees_Table a
You could use below one as well.
create view bonusview as
select
e.EmployeeName,e.YearsOfService, b.bonus
from
Employees_Table e
inner join Bonus_Table b on b.MinimumYears = Floor(e.YearsOfService)

The second solution requires an entry for each possible year in the Bonus table. In the current setup an employee with 3 years won't get any bonus at all since the 'Floor(X)' is trying to match a 3 in the bonus table and an entry with 3 years does not exist. Thanks for your prompt reply.
