为保护目的，信息已被更改。所以说我需要能够列出所有具有“收到”活动而不是ABC银行“已交付”活动的分配订单，我需要返回客户名称，客户ID，贷款编号和“收到日期”（收到的活动日期））。我已经能够完成所有工作，但是，我无法删除任何没有“已交付”活动的文件。以下是我到目前为止的情况：

SELECT tblCustomer.CustomerName, tblCustomer.CustomerID, tblOrder.LoanNumber, (tblOrderActivity.ActivityDate) AS [received date]
FROM tblOrderActivity (NOLOCK)

INNER JOIN tblOrder (NOLOCK)
ON tblOrderActivity.OrderID = tblOrder.OrderID

INNER JOIN tblCustomer (NOLOCK)
ON tblOrder.CustomerID = tblCustomer.CustomerID

INNER JOIN tblOrderType (NOLOCK)
ON tblOrder.OrderTypeID = tblOrderType.OrderTypeID

INNER JOIN tblActivity (NOLOCK)
ON tblActivity.ActivityID = tblOrderActivity.ActivityID

WHERE tblOrderType.OrderTypeName = 'Assignment' 
AND EXISTS (SELECT DISTINCT [OrderID] FROM [tblOrderActivity] WHERE tblActivity.ActivityName = 'Received')
AND NOT EXISTS (SELECT DISTINCT [OrderID] FROM [tblOrderActivity] WHERE tblActivity.ActivityName = 'Delivered To Customer')

GROUP BY tblCustomer.CustomerName, tblCustomer.CustomerID, tblOrder.LoanNumber, tblOrderActivity.ActivityDate;

我的结果低于

CustomerName   CustomerID      LoanNumber    received date
 ----------    ------------    -----------   ----------
 ABC Bank      1               45565584      2007-04-16 08:34:00.000
 ABC Bank      1               45566856      2007-04-16 08:34:00.000
 ABC Bank      1               45584565      2007-04-16 08:34:00.000
 ABC Bank      1               45588545      2007-04-16 08:34:00.000

Answer 1

试试这个。不是世界上最有效的t-sql，但架构没有多大帮助。可能需要对主查询中的表进行别名以使其更具可读性，并确保子查询正常工作（至少这是我通常所做的）。

这应该返回所有没有交付的已接收记录

SELECT tblCustomer.CustomerName, tblCustomer.CustomerID, tblOrder.LoanNumber, (tblOrderActivity.ActivityDate) AS [received date]
FROM tblOrderActivity (NOLOCK)

INNER JOIN tblOrder (NOLOCK)
ON tblOrderActivity.OrderID = tblOrder.OrderID

INNER JOIN tblCustomer (NOLOCK)
ON tblOrder.CustomerID = tblCustomer.CustomerID

INNER JOIN tblOrderType (NOLOCK)
ON tblOrder.OrderTypeID = tblOrderType.OrderTypeID

INNER JOIN tblActivity (NOLOCK)
ON tblActivity.ActivityID = tblOrderActivity.ActivityID

WHERE tblOrderType.OrderTypeName = 'Assignment' 

AND NOT EXISTS (SELECT 1 FROM [tblOrderActivity] WHERE OA.ActivityID = 4 AND OA.OrderID = tblOrder.OrderID)  --Delivered Excluded
AND tblOrderActivity.ActivityID = 1  --Received Only

Answer 2

以下是我将如何进行查询

SELECT * 
FROM tblOrder
LEFT JOIN (
    SELECT 'r' AS r, tblOrderActivity.ActivityDate, tblActivity.ActivityName, tblOrderActivity.OrderID
    FROM tblOrderActivity
    JOIN tblActivity ON tblOrderActivity.ActivityID = tblActivity.ActivityID 
        AND tblActivity.ActivityName = 'Received'
) AS Received ON tblOrder.OrderID = Received.OrderID
LEFT JOIN (
    SELECT 'd' AS d, tblOrderActivity.ActivityDate, tblActivity.ActivityName, tblOrderActivity.OrderID
    FROM tblOrderActivity
    JOIN tblActivity ON tblOrderActivity.ActivityID = tblActivity.ActivityID 
        AND tblActivity.ActivityName = 'Delivered To Cusotmer'
) AS Delivered ON tblOrder.OrderID = Delivered.OrderID
WHERE Delivered.ActivityDate IS NULL

或者像这样

SELECT * 
FROM tblOrder
LEFT JOIN (
    SELECT 'r' AS r, tblOrderActivity.ActivityDate, tblActivity.ActivityName, tblOrderActivity.OrderID
    FROM tblOrderActivity
    JOIN tblActivity ON tblOrderActivity.ActivityID = tblActivity.ActivityID 
        AND tblActivity.ActivityID IN (SELECT ActivityID FROM tblActivity WHERE tblActivity.ActivityName = 'Received')
) AS Received ON tblOrder.OrderID = Received.OrderID
LEFT JOIN (
    SELECT 'd' AS d, tblOrderActivity.ActivityDate, tblActivity.ActivityName, tblOrderActivity.OrderID
    FROM tblOrderActivity
    JOIN tblActivity ON tblOrderActivity.ActivityID = tblActivity.ActivityID 
        AND tblActivity.ActivityID IN (SELECT ActivityID FROM tblActivity WHERE tblActivity.ActivityName = 'Delivered To Cusotmer')
) AS Delivered ON tblOrder.OrderID = Delivered.OrderID
WHERE Delivered.ActivityDate IS NULL

将其修剪为您想要的列

排除sql中的某些方面

tblCustomer

tblOrderType

tblActivity

tblOrder

tblOrderActivity
