SQL多帶計數

Question

我需要參加3個不同的MySQL表連接：

• 的問題表（代表questio）
• 的問題投票表格（表示喜歡的問題時，登錄= 1不同於當Sign = 0時）
• 答案表（表示具有對特定問題的答案的表）。

這三個表有這樣的結構：

Questions 
-------------------------------------------- 
| ID | UserID | Title | Body | Date 
-------------------------------------------- 
| 1 | 32 | Is it raining? | BodyQuestion | 01/01/2016 
| 2 | 45 | Who are we? | BodyQuestion | 02/02/2016 
-------------------------------------------- 


QuestionsVotes 
-------------------------------------------- 
| ID | QuestionID | Sign 
-------------------------------------------- 
| 1 | 1   | 1 
| 2 | 2   | 1 
| 3 | 1   | 0 
| 4 | 1   | 1 
| 5 | 2   | 0 

Answers 
-------------------------------------------- 
| ID | QuestionID | UserID | Body 
-------------------------------------------- 
| 1 | 1 | 45 | Yes, it is. 
| 2 | 2 | 10 | Tricky question... 
| 3 | 1 | 67 | In Barcelona it is not 

我需要的是返回一個SQL查詢，給出問題的ID，以儘可能多的行返回的答案的問題已收到數每一個都與Questions.ID，Questions.UserID，Questions.Title，Questions.Body，Questions.Date，與問題相關的喜歡，與問題相關的unlikes，Answers.ID，Answers.UserID。如您所見，行之間的唯一更改是Answers字段。

SQL Output (for Question with ID=1) 
-------------------------------------------- 
| ID | UserID | Title | Body | Date | Likes | Unlikes | AnswerID | AnswerUserID 
-------------------------------------------- 
| 1 | 32 | Is it raining? | BodyQuestion | 01/01/2016 | 2 | 1 | 1 | 45 
| 1 | 32 | Is it raining? | BodyQuestion | 01/01/2016 | 2 | 1 | 3 | 67 

EDIT 1：實施例給出。

Answer 1

嘗試這種情況：

SELECT `ID` , `UserID` , `Title`, `Body`, `Date`, `Likes`, `Unlikes`, `AnswerID`, `AnswerUserID` 
FROM QUESTIONS q 
INNER JOIN ANSWERS a ON q.`ID` = a.`QuestionID` 
INNER JOIN QuestionVotes v ON q.`ID` = v.`QuestionID`
