sql - SQL 查询中的语法错误

Question

DECLARE @startRowIndex int  
  set @startRowIndex=0
  Declare @maximumRows int 
  set @maximumRows=5

SET ROWCOUNT 5;

WITH OrderedEmployees As

SELECT *, ROW_NUMBER() OVER (Order By EmployeeID ASC) as RowNum FROM Employees 

 SELECT * FROM OrderedEmployees Where RowNum > @startRowIndex
 Order By EmployeeID ASC

我从一个网站上得到了这个查询，但是当我在 SQL Server Management Studio 中运行它时，它给了我以下错误，请帮帮我，我直觉这只是一个语法错误，让我很困惑，请帮帮我

关键字“SELECT”附近的语法不正确

我相信这就是你想要的：

DECLARE @startRowIndex int  
  set @startRowIndex=0
  Declare @maximumRows int 
  set @maximumRows=5

SET ROWCOUNT 5

;WITH OrderedEmployees As
(
    SELECT *, ROW_NUMBER() OVER (Order By EmployeeID ASC) as RowNum 
    FROM Employees 
)
SELECT * 
FROM OrderedEmployees 
Where RowNum > @startRowIndex
Order By EmployeeID ASC

不过，我真的不知道你为什么选择使用ROWCOUNT而不是仅仅过滤你的 CTE。我会使用：

DECLARE @startRowIndex int  
  set @startRowIndex=0
  Declare @maximumRows int 
  set @maximumRows=5

;WITH OrderedEmployees As
(
    SELECT *, ROW_NUMBER() OVER (Order By EmployeeID ASC) as RowNum 
    FROM Employees 
)
SELECT * 
FROM OrderedEmployees 
Where RowNum > @startRowIndex AND RowNum <= @maximumRows
Order By EmployeeID ASC
