如何修改 SQL 中的 Row_Number 语法，以便根据条件分配行号？

Question

我正在使用 SQL Server 2014 并且我有以下 T-SQL 查询：

SELECT  
    d.PropertyCode,
    b.ProfileID, 
    a.RSY_RESERVATIONSTAYID, 
    b.StatusCode, c2.CreatedOn AS 'Original CreatedOn',
    a.RSY_UDFCHAR07 AS 'Original PMS No', 
    c2.ReservationStayID AS 'Original Resa ID',
    b.CreatedOn, 
    b.PMSConfirmationNumber, 
    ROW_NUMBER() OVER (PARTITION BY b.ProfileID ORDER BY Count(*) DESC)  AS rownum
FROM 
    ReservationStay b
LEFT JOIN 
    P5RESERVATIONSTAY a ON a.RSY_RESERVATIONSTAYID = b.ReservationStayID
LEFT JOIN
    GuestNameInfo c on c.Reservationstayid = b.ReservationStayID
LEFT JOIN
    RESERVATIONSTAY c2 on  c2.PMSConfirmationNumber = a.RSY_UDFCHAR07
LEFT JOIN
    GuestStaySummary d ON d.ReservationStayID = b.ReservationStayID

这是我的输出的摘录：

PropertyCode    ProfileID  ....       CreatedOn     ....      rownum

  AXL             90072        2015-06-03 14:15:27.000        1
  AXL             90072        2015-03-16 19:10:27.000        2

我需要根据 CreatedOn 日期分配 rownum。换言之，对于 ProfileID 90072，将在 CreatedOn = 2015-03-16 处分配行号 1，在 CreatedOn = 2015-06-03 处分配行号 2。

为简化起见，rownum 按其创建日期的升序分配给 ProfileID。

如何修改我的 row_number 语法来实现此目的？

Answer 1

ROW_NUMBER() OVER (PARTITION BY b.ProfileID ORDER BY CreatedOn ASC)  AS rownum
