2行のデータを連結する

Question

私は以下のデータを持っています。どこでもFirstNameは空白です。前の行のNoteの最後にそのNoteデータを結合したいと思います。この例は、並べ替えのないテーブルにデータがどのように表示されるかです。 SQLを介して結果テーブルを達成する方法はありますか？助けてくれてありがとう！

FirstName LastName Note 
--------- ------- -------------------------------------- 
John  Doe  likes bananas 
Steve  Weiss  likes tomatoes and 
         also likes potatoes 
John  Weiss  likes apples 
Jeff  Marki  likes hotdogs 
         and also likes hambugers 
Jenny  Boper  likes peaches

Answer 1

Declare @YourTable table (FirstName varchar(50),LastName varchar(50),Note varchar(500)) 
Insert Into @YourTable values 
('John','Doe','likes bananas'), 
('Steve','Weiss','likes tomatoes and'), 
(''  ,'','also likes potatoes'), 
('John','Weiss','likes apples'), 
('Jeff','Marki','likes hotdogs'), 
('' ,'','and also likes hambugers'), 
('Jenny','Boper','likes peaches') 

Select FirstName 
     ,LastName 
     ,Note  = FullText 
From (
     Select * 
       ,FullText = Note+IIF(Lead(FirstName,1) over (Order By (Select null))='',' '+Lead(Note,1) over (Order By (Select Null)),'') 
     From @YourTable 
    ) A 
Where FirstName <>'' 

戻り

FirstName LastName Note 
John  Doe   likes bananas 
Steve  Weiss  likes tomatoes and also likes potatoes 
John  Weiss  likes apples 
Jeff  Marki  likes hotdogs and also likes hambugers 
Jenny  Boper  likes peaches

別の解決策：

DECLARE @TEMP_DATA TABLE 
    (
    ID INT IDENTITY(1,1), 
    FIRSTNAME NVARCHAR(50), 
    LASTNAME NVARCHAR(50), 
    NOTE NVARCHAR(50) 
    ) 

DECLARE @NO_NAME TABLE 
    (
    IDEMPTY INT, 
    EMPTYNAME NVARCHAR(50), 
    EMTPYNAME NVARCHAR(50), 
    NOTE2 NVARCHAR(50) 
    ) 

INSERT INTO @TEMP_DATA 
SELECT * 
FROM DATA 

INSERT INTO @NO_NAME 
SELECT * 
FROM @TEMP_DATA 
WHERE FIRSTNAME='' 

UPDATE @TEMP_DATA 
SET  NOTE=NOTE+' '+NOTE2 
FROM @NO_NAME N 
WHERE ID=IDEMPTY-1 

SELECT FIRSTNAME,LASTNAME,NOTE FROM @TEMP_DATA WHERE NOT FIRSTNAME LIKE ''
