Question

我有以下查询，该查询应显示过去3个月的结果：

SELECT COUNT(DISTINCT dbo.UserQuiz.QuizID) AS [Total Number of Quizzes],
   dbo.Divisions.DivisionName, 
   DATENAME(Month, dbo.UserQuiz.DateTimeComplete) AS Month 
FROM dbo.UserQuiz 
INNER JOIN dbo.Quiz 
  ON dbo.UserQuiz.QuizID = dbo.Quiz.QuizID 
INNER JOIN dbo.employee 
  ON dbo.UserQuiz.Username = dbo.employee.Username 
RIGHT OUTER JOIN dbo.Divisions 
  ON dbo.employee.DivisionCode = dbo.Divisions.SapCode 

GROUP BY dbo.Divisions.DivisionName, 
  DATENAME(Month, dbo.UserQuiz.DateTimeComplete) 
HAVING (DATENAME(Month, GETDATE()) - 
        DATENAME(Month, dbo.UserQuiz.DateTimeComplete) > 3

此查询现在出现的问题是当我尝试在SQLServer Management Studio 2008 R2中执行它时，出现以下错误，我不知道原因：

Msg 102，Level 15，State 1，Line 5'3'附近的语法不正确。

Answer 1

在3之后需要一个末端括号。

SELECT     
    COUNT(DISTINCT dbo.UserQuiz.QuizID) AS [Total Number of Quizzes],   
    dbo.Divisions.DivisionName, 
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete)  AS Month 

FROM dbo.UserQuiz 

INNER JOIN dbo.Quiz 
ON dbo.UserQuiz.QuizID = dbo.Quiz.QuizID 

INNER JOIN dbo.employee 
ON dbo.UserQuiz.Username = dbo.employee.Username 

RIGHT OUTER JOIN dbo.Divisions 
ON dbo.employee.DivisionCode = dbo.Divisions.SapCode 

GROUP BY dbo.Divisions.DivisionName, 
DATENAME(Month, dbo.UserQuiz.DateTimeComplete) 

HAVING (
    DATENAME(Month, GETDATE()) 
    - DATENAME(Month, dbo.UserQuiz.DateTimeComplete) > 3
) -- you were missing this parenthesis

Answer 2

我相信你在某个地方错过了一个'）'。

HAVING (DATENAME(Month, GETDATE()) - DATENAME(Month, dbo.UserQuiz.DateTimeComplete) > 3

为什么我的查询出错？
