我们如何在存储过程中更改视图？

create procedure createviewupdatepenaltypointsconsecutive
as
begin
alter VIEW consecutive
as


WITH cte as (
    SELECT *, 
           LAG([pointsRewarded], 1) OVER (PARTITION BY [EmployeeID] ORDER BY [WeekNumber]) as prev1_points,
           LAG([pointsRewarded], 2) OVER (PARTITION BY [EmployeeID] ORDER BY [WeekNumber]) as prev2_points,
           LAG([pointsRewarded], 3) OVER (PARTITION BY [EmployeeID] ORDER BY [WeekNumber]) as prev3_points
    FROM week1
)
SELECT *,
       CASE WHEN [pointsRewarded] = -10 AND prev1_points = -10  AND prev2_points = -10  AND prev3_points = -10 
            THEN -200
            WHEN [pointsRewarded] = -10 AND prev1_points = -10  AND prev2_points = -10 
            THEN -100
            WHEN [pointsRewarded] = -10 AND prev1_points = -10
            THEN -50
            ELSE 0
       END penalty       
FROM cte

end

M收到此错误： 消息156，级别15，状态1，过程createviewupdatepenaltypointsconsecutive，第4行关键字＆＃39; VIEW＆＃39;附近的语法不正确。消息319，级别15，状态1，过程createviewupdatepenaltypointsconsecutive，第8行关键字＆＃39;与＆＃39;附近的语法不正确。如果此语句是公用表表达式，xmlnamespaces子句或更改跟踪上下文子句，则必须以分号结束前一个语句。

您将无法在存储过程中运行http://uvw.mydomain.com:8091/myApp语句。因此，要解决您的问题，您必须采取以下两种措施：

1）要纠正当前出现的错误，您必须使用分号开始CTE：

ALTER VIEW

（或者甚至更好地开始用分号终止所有SQL语句，因为不推荐使用替代方法）。

2）在动态SQL字符串中转换alter view语句并使用WITH cte as ( SELECT *, LAG([pointsRewarded], 1) OVER (PARTITION BY [EmployeeID] ORDER BY [WeekNumber]) as prev1_points, LAG([pointsRewarded], 2) OVER (PARTITION BY [EmployeeID] ORDER BY [WeekNumber]) as prev2_points, LAG([pointsRewarded], 3) OVER (PARTITION BY [EmployeeID] ORDER BY [WeekNumber]) as prev3_points FROM week1) SELECT *, CASE WHEN [pointsRewarded] = -10 AND prev1_points = -10 AND prev2_points = -10 AND prev3_points = -10 THEN -200 WHEN [pointsRewarded] = -10 AND prev1_points = -10 AND prev2_points = -10 THEN -100 WHEN [pointsRewarded] = -10 AND prev1_points = -10 THEN -50 ELSE 0 END penalty FROM cte执行它，因为sp_executesql语句必须是批处理中的第一个：

ALTER VIEW
