從單一的表有兩個不同的員工ID在一個單一的存儲過程中選擇兩個員工姓名

Question

我試圖從一開始就解決了這個以下查詢，但我沒有得到該出把..

查詢：

select distinct L.LeadBudget,L.CompanyName,L.LeadTitle,L.Status, 
E.Name as OwnerName,E.Name as 
CreatedUser 
from Leads L,Employee E where L.LeadId='2' 
and E.EmployeeId=L.LeadOwner and E.EmployeeId=L.CreatedUserId 

在上面的查詢我想

E.Name as OwnerName and E.Name as CreatedUser 
from a single Employee tables)..where E.EmployeeId=L.LeadOwner and 
E.EmployeeId=L.CreatedUserId 

，如果我用了OWNERNAME執行或創建的用戶我得到我想要得到這兩個名字data..but。

我建議使用更現代的JOIN風格;而不是列出多個talbes，並在WHERE中做所有事情。 基本上要實現你想要做的事情，你需要爲兩名員工執行JOIN。

SELECT l.LeadBudget, l.CompanyName, l.LeadTitle, l.Status, leadEmp.Name As OwnerName, createdEmp.Name As CreatedUser 
FROM Leads l 
    INNER JOIN Employee leadEmp ON(l.LeadOwner = leadEmp.EmployeeId) 
    INNER JOIN Employee createdEmp ON(l.CreatedUserId= createdEmp.EmployeeId) 
WHERE l.LeadId='2'
