MySQL存儲過程 - 計算付費差異

Question

我面臨一個問題，試圖爲工資報告提供一個MySQL存儲過程。以前的員工工資率只允許在薪酬期間開始時更改。但是，現在他們可以在支付期間進行更改，並且報告需要在支付期間考慮不同的工資率。支付期限爲兩週。

我有以下查詢，這是非常混亂，它的工作原理，但沒有考慮到薪酬階段中的薪酬變化。

注：日期是硬編碼作爲一個例子

SELECT 
    e.EmployeeID AS EmployeeID, 
    CONCAT(e.LastName, ', ', e.FirstName) AS Resource,

    ) OR e.Status = 'Active') 
AND (e.ResourceTypeID = 2 OR e.ResourceTypeID = 4) 
GROUP BY Resource 
ORDER BY Role, Resource ASC 

最終報告的列應。

EmployeeID，LastName，FirstName，RegularHours，PTO，Holiday，FloatingHoliday，Total和GrossEarnings。

我對存儲過程並不是很有經驗，但我想我需要使用遊標來遍歷每個日期並計算出應用於此的付費率。

無論如何，這個SQL將創建數據結構。

讓我冷凝您使用到的東西多一點可讀性的sql開頭：

Select e.employeeid as EmployeeID 
    , Concat(e.LastName, ', ', e.FirstName) AS Resource 
    , sum(case when p.projectid not in (24,29,606,614,746) then td.BillableHours else 0 end) as RegularHours 
    , sum(case when p.projectid in (29,614) then td.BillableHours else 0 end) as PTO 
    , sum(case when p.projectid = 24 then td.BillableHours else 0 end) as Holiday 
    , sum(case when p.projectid = 746 then td.BillableHours else 0 end) as FloatingHoliday 
    , sum(case when p.projectid != 606 then td.BillableHours else 0 end) as Total 
    , EPR.Rate as PayRate 
    , sum(case when p.projectid != 606 then td.BillableHours else 0 end) * EPR.Rate as GrossEarnings 
From Employee e 
    Join Timesheets t on e.EmployeeID = t.EmployeeID 
    join TimesheetDetails td on t.TimeCardID = td.TimeCardID 
    join Projects p on p.ProjectID = td.ProjectID 
    join EmployeePayRate epr on epr.EmployeeID = e.EmployeeID 
    and epr.StartDate <= td.WorkDate 
where ((td.BillableHours > 0) 
     or (e.Status = 'Active')) 
    and td.WorkDate BETWEEN '2015-01-17' AND '2015-01-30' 
Group by e.employeeid 
    , Concat(e.LastName, ', ', e.FirstName) 
    , EPR.Rate 

如果看起來可以接受的，現在我們進入了事情的肉加入到員工的工資率。我們從1到1到多到1，這樣可以改變分組。問題是如果一個員工在一段時間內有兩個（或更多）工資率，您是否想要顯示他在每個工資率期間所做的工作細目。我發現你一週沒有做一週的工作，所以你沒有計算加班時間，所以我猜這是一份加班前的綜合報告，只是一目瞭然地估計工資，因此知道多少小時的paygrade可能並不重要。銘記想到這裏是我們如何改變連接：

join EmployeePayRate epr on epr.EmployeeID = e.EmployeeID 
    and epr.StartDate <= td.WorkDate 

如果您有payrates的開始日期和結束日期的加入改變

join EmployeePayRate epr on epr.EmployeeID = e.EmployeeID 
    and epr.StartDate <= '2015-01-17' 
    and ((epr.endDate is null) or (epr.endDate >= '2015-01-17')) 
    join TimesheetDetails td on t.TimeCardID = td.TimeCardID 
    and ((epr.EndDate is null and td.WorkDate between epr.StartDate and '2015-01-30') 
     or (epr.EndDate is not null and td.WorkDate between epr.StartDate and epr.EndDate)) 

你會注意到或聲明，我們試圖避免使用諸如isnull（）這樣的函數，以便我們可以使用索引。這讓我想到下一點，如果你沒有結束日期列，事情會變得更加複雜。但是，不要寫出可能不必要的整個解決方案，讓我知道如果是這樣的話，我們會弄清楚它。
