存储过程中的CTE不工作

Question

我有一个存储过程，它正在构建稍后在查询中调用的表。我不得不添加使用CTE的新表，但现在当我使用；为了结束表达式，我得到了一个错误"；"附近的语法不正确当我删除它时，我得到了一个错误，我需要一个；具有CTE。查询本身在存储过程之外工作。任何帮助都将不胜感激。。。。

set @cdq = 'insert #REMOVAL_FLAG
(
    MYKEY,
    REMOVAL_FLAG
)
    WITH 
create_key AS(
        SELECT *,
        (CONVERT(varchar(25), a.NDC11, 101) + CONVERT(varchar(25), a.PharmacyID, 101) + CONVERT(varchar(50),ABS(a.TotalNetCost),101)) as REVERSAL_KEY
        FROM table1 a
),
find_rev AS (
        SELECT *,
            CASE
                WHEN MIN(TotalAmount) OVER (PARTITION BY REVERSAL_KEY) < 0 THEN 1 ELSE NULL
            END as Flag
        FROM create_key
),
primary_flag as (
        SELECT TOP 1500000 *,
            DENSE_RANK() OVER (ORDER BY REVERSAL_KEY) as [GROUP],
            ROW_NUMBER() OVER (PARTITION BY NDC11, PharmacyID, TotalNetCost ORDER BY REVERSAL_KEY) as PK
        FROM find_rev
        WHERE Flag = 1
        ORDER BY [GROUP], PK
),
flagged as (
        SELECT *,
            CASE
                WHEN COUNT (PK) OVER (PARTITION BY [GROUP], PK) > 1 THEN ''REMOVE''
            END as REMOVAL_FLAG
        FROM primary_flag
)
SELECT a1.MYKEY, f.REMOVAL_FLAG
FROM table1 a1
LEFT OUTER JOIN flagged f ON (f.MYKEY = a1.MYKEY)

insert语句可以使用CTE（with表达式）。在SQL Server中，它位于insert之前，而不是select:之前

WITH 
create_key AS(
        SELECT *,
        (CONVERT(varchar(25), a.NDC11, 101) + CONVERT(varchar(25), a.PharmacyID, 101) + CONVERT(varchar(50),ABS(a.TotalNetCost),101)) as REVERSAL_KEY
        FROM table1 a
),
find_rev AS (
        SELECT *,
            CASE
                WHEN MIN(TotalAmount) OVER (PARTITION BY REVERSAL_KEY) < 0 THEN 1 ELSE NULL
            END as Flag
        FROM create_key
),
primary_flag as (
        SELECT TOP 1500000 *,
            DENSE_RANK() OVER (ORDER BY REVERSAL_KEY) as [GROUP],
            ROW_NUMBER() OVER (PARTITION BY NDC11, PharmacyID, TotalNetCost ORDER BY REVERSAL_KEY) as PK
        FROM find_rev
        WHERE Flag = 1
        ORDER BY [GROUP], PK
),
flagged as (
        SELECT *,
            CASE
                WHEN COUNT (PK) OVER (PARTITION BY [GROUP], PK) > 1 THEN ''REMOVE''
            END as REMOVAL_FLAG
        FROM primary_flag
)
insert #REMOVAL_FLAG(MYKEY, REMOVAL_FLAG)
    SELECT a1.MYKEY, f.REMOVAL_FLAG
    FROM table1 a1
    LEFT OUTER JOIN flagged f ON (f.MYKEY = a1.MYKEY)
