我的SQL代码没有为我的查询返回任何行

Question

im trying to write a query that will display for each of my employee member the total the employee was contracted to work, the number of hours classed as overtime they worked and the total pay received by that employee for the financial year 2015 which should run from 1st of april 2014 to the 31st of march 2015 however my query doesnt return any values. now i have a table that is called payroll that iis connected to the employee table via a foreign key, and it also has a foreign key to reference the timesheet of the employee. i want my output to be something like this:

END OF YEAR REPORT

BALDROY BARD was contracted for 228 hours, earned £2884.5 basic and £1604.25 in OT. Total earnings were £4488.75 Pension paid was £145.35

now i have data inserted to these tables that ensures that this query will return at least one record.

just dont understand why it wont return any records. i haven't included "create view" in the code below because i dont want to keep creating the view and deleting it.

SELECT  emp_firstname || ' '|| emp_surname || ' was contracted for ' ||  sum(grade_hours) || ' hours, earned £ ' ||sum(Payroll_standard)|| ' basic and £' ||
      sum(Payroll_overtime) || 'in overtime. Total earnings were ' || ( sum(Payroll_overtime) + sum(Payroll_standard)) || ' Pension paid was ' || sum(Payroll_pension) as "END OF YEAR REPORT" 
      from Funtom_employee left join Funtom_payroll on Payroll_emp = emp_ID
      join funtom_grade on grade_id = emp_grade
      where payroll_date between '01-apr-14' and '31-mar-15'
      group by emp_firstname, emp_surname;

Give this a try, that's all I can propose with what you have shown.

SELECT ( 
        emp_firstname || ' ' || emp_surname || 
        ' was contracted for ' ||  sum(grade_hours) || 
        ' hours, earned £' || sum(Payroll_standard) || 
        ' basic and £' || sum(Payroll_overtime) || 
        ' in overtime. Total earnings were ' || ( sum(Payroll_overtime) + sum(Payroll_standard)) || 
        ' Pension paid was ' || sum(Payroll_pension) 
       ) as "END OF YEAR REPORT" 
from Funtom_employee 
  left join Funtom_payroll on Funtom_payroll.Payroll_emp = Funtom_employee.emp_ID
  inner join funtom_grade on funtom_grade.grade_id = Funtom_employee.emp_grade
where payroll_date between '01-apr-14' and '31-mar-15'
group by emp_firstname, emp_surname;    

You should really add a SQL fiddle if it doesn't work
