递归比较一条记录与前一条记录的查询

Question

我有下表示例

CREATE TABLE [dbo].[Transactions](
    [TransactionID] [int] IDENTITY(1,1) NOT NULL,
    [TransactionTypeID] [int] NOT NULL,
    [Counter] [int] NOT NULL,
    [GivenCounter] [int] NOT NULL,
    [ExecutionDate] [datetime] NOT NULL,
 CONSTRAINT [PK_Transactions] PRIMARY KEY CLUSTERED ([TransactionID] ASC)

TransactionTypeID 字段标识交易类型：

• 1 表示激活
• 2 表示消耗
• 3 表示取消

特别是type 3 是指取消之前的交易。因此，如果在取消之前已经执行的交易（以 ExecutionDate 而言）是type 2，则意味着取消消费，而如果之前的交易是type 1，则意味着取消是取消激活。

如何只查询含义为停用的交易（type 3 与之前的type 1）？ 有人可以帮忙吗？

编辑：添加了一些示例数据以更好地解释

TransactionID   TransactionTypeID   Counter  GivenCounter    ExecutionDate  
--------------  -----------------   -------  ------------    -----------------------
138327              1               1          0             2014-07-20 07:14:08.000
134175              2               0          1             2014-07-21 12:39:12.000
137620              3               1          1             2014-07-22 20:19:06.000
134199              1               1          0             2014-07-23 10:09:52.000
132772              3               0          1             2014-07-24 08:18:23.000

在这个例子中，我的查询应该只提取一条记录 (TransactionID 132772)，因为它取消了之前的交易，TransactionTypeID 等于 1

Answer 1

我会这样做：

SELECT a.transactionid 
FROM   (SELECT *, Row_number() OVER(ORDER BY ExecutionDate) AS Rownumber 
        FROM   transactions) a 
       JOIN (SELECT transactiontypeid, Row_number()  OVER( ORDER BY ExecutionDate) AS Rownumber 
             FROM   transactions) b 
         ON a.rownumber = b.rownumber + 1 
WHERE  a.transactiontypeid = 1 
       AND b.transactiontypeid = 3 

Answer 2

我已经更新了我的答案，你可以试试这个吗？

SELECT *
FROM
(
SELECT 
DENSE_RANK() OVER (PARTITION BY (TransactionTypeID) ORDER BY (ExecutionDate)) AS 'RowNo',
TransactionID, TransactionTypeID, ExecutionDate
FROM dbo.Transactions2
WHERE TransactionTypeID = 3
 ) AS A
WHERE RowNo = 2;
