「必須聲明表變量」錯誤與CTE

Question

我在SQL Server 2005中使用CTE內部的表變量時出現以下錯誤。當我使用物理表時，它工作正常。

必須聲明表變量「@Employee」。
'）'附近語法不正確。

代碼：

DECLARE @Emploee TABLE (EmpID INT, EmpName VARCHAR(50), Dept VARCHAR(5), Manager INT) 

INSERT INTO @Emploee VALUES (1, 'A', NULL,NULL) 
INSERT INTO @Emploee VALUES (2, 'B', 'D100',NULL) 

;WITH EmployeeManagers AS 
(
    SELECT e.EmpId, e.EmpName, 1 AS Level 
     , e.Manager, e.EmpID CurrLevelEmpID, Cast(Null as VarChar(5)) Dept 
    FROM @Employee AS e 
    WHERE e.Manager IS NOT NULL 

    UNION ALL 

    SELECT em.EmpId, em.EmpName, Level + 1 AS Level 
     , e.Manager, e.EmpID CurrLevelEmpID, e.Dept Dept 
    FROM EmployeeManagers em 
     INNER JOIN Employee e ON e.EmpId = em.Manager 
) 
SELECT * FROM EmployeeManagers 

我們怎樣才能解決這個錯誤？

DECLARE @Emploee TABLE (EmpID INT, EmpName VARCHAR(50), Dept VARCHAR(5), Manager INT) 

INSERT INTO @Emploee VALUES (1, 'A', NULL,NULL) 
INSERT INTO @Emploee VALUES (2, 'B', 'D100',NULL) 

;WITH EmployeeManagers AS 
(
    SELECT e.EmpId, e.EmpName, 1 AS Level 
     , e.Manager, e.EmpID CurrLevelEmpID, Cast(Null as VarChar(5)) Dept 
    FROM @Emploee AS e   --<-- Wrong Spellings here 
    WHERE e.Manager IS NOT NULL 

    UNION ALL 

    SELECT em.EmpId, em.EmpName, Level + 1 AS Level 
     , e.Manager, e.EmpID CurrLevelEmpID, e.Dept Dept 
    FROM EmployeeManagers em 
     INNER JOIN @Emploee e ON e.EmpId = em.Manager --<-- Mising @ sign here 
) 
SELECT * FROM EmployeeManagers

你有一個錯字：

DECLARE @Emploee TABLE (EmpID INT, EmpName VARCHAR(50), Dept VARCHAR(5), Manager INT) 

INSERT INTO @Emploee VALUES (1, 'A', NULL,NULL) 
INSERT INTO @Emploee VALUES (2, 'B', 'D100',NULL) 

應該@Employee
