Du vil ikke være i stand til at køre ALTER VIEW
erklæring som den i din lagrede procedure. Så for at løse dit problem skal du tage 2 handlinger:
1) For at rette den fejl, der vises i øjeblikket, skal du begynde CTE med et semikolon som dette:
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
(Eller endnu bedre begynde at afslutte alle dine SQL-sætninger med semikolon, da alternativet er forældet).
2) Konverter din alter view-sætning i en dynamisk SQL-streng og kør den ved hjælp af sp_executesql
som ALTER VIEW
sætningen skal være den første i batchen:
CREATE PROCEDURE createviewupdatepenaltypointsconsecutive
AS
BEGIN
DECLARE @STMT AS NVARCHAR(MAX) =
'
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
'
EXEC sp_executesql @STMT;
END
