連接兩個表要在一個GridView

Question

我越來越困惑於如何構建SQL查詢的時候纔來連接兩個表，這樣我以後可以到GridView綁定受其約束。

基本上我有兩個表，

tablename: family 
__________________________ 
|Status |lastName|firstName| 
|-------|--------|---------| 
|1  |11  |111  | 
|2  |22  |222  | 
|3  |33  |333  | 
'''''''''''''''''''''''''''' 
      + 

tablename: familyStatus 
_____________________ 
|id  | Notes | 
|----------|----------| 
|1   | 1111  | 
|2   | 2222  | 
|3   | 3333  | 
''''''''''''''''''''''' 

      = 

Joined-tables: family+familyStatus [this is what i want] 
____________________________ 
|firstName | lastName |Notes | 
|----------|----------|------| 
|111  | 11  |1111 | 
|222  | 22  |2222 | 
|333  | 33  |3333 | 
'''''''''''''''''''''''''''''' 

什麼你這裏看到的是，狀態從表家庭和ID從familyStatus是相同的密鑰，身份和id會隱藏在gridview上。

Lets just assume for now that this is how i get the family table. 

SELECT Status, firstName, lastName 
FROM family 
WHERE firstName= @fN 
AND lastName = @lN 

我需要在這裏添加什麼，以便來自family表的Notes也被加入？

Answer 1

聯接：

SELECT F.firstName, F.lastName, FS.Notes 
FROM family F 
INNER JOIN familyStatus FS 
    ON F.[Status] = FS.id 
WHERE F.firstName= @fN 
AND F.lastName = @lN 

Answer 2

添加狀態外鍵familyStatus表，請嘗試以下操作：

SELECT firstName, lastName, Notes 
FROM family JOIN familyStatus 
ON family.Status = familyStatus.Status 
WHERE firstName= @fN 
AND lastName = @lN
